Authorization and Governance for AI Agents: Runtime Authorization Beyond Identity at Scale
Designing Authorization‑Aware AI Agents at Scale Enforcing Runtime RBAC + ABAC with Approval Injection (JIT) Microsoft Entra Agent Identity enables organizations to govern and manage AI agent identities in Copilot Studio, improving visibility and identity-level control. However, as enterprises deploy multiple autonomous AI agents, identity and OAuth permissions alone cannot answer a more critical question: “Should this action be executed now, by this agent, for this user, under the current business and regulatory context?” This post introduces a reusable Authorization Fabric—combining a Policy Enforcement Point (PEP) and Policy Decision Point (PDP)—implemented as a Microsoft Entra‑protected endpoint using Azure Functions/App Service authentication. Every AI agent (Copilot Studio or AI Foundry/Semantic Kernel) calls this fabric before tool execution, receiving a deterministic runtime decision: ALLOW / DENY / REQUIRE_APPROVAL / MASK Who this is for Anyone building AI agents (Copilot Studio, AI Foundry/Semantic Kernel) that call tools, workflows, or APIs Organizations scaling to multiple agents and needing consistent runtime controls Teams operating in regulated or security‑sensitive environments, where decisions must be deterministic and auditable Why a V2? Identity is necessary—runtime authorization is missing Entra Agent Identity (preview) integrates Copilot Studio agents with Microsoft Entra so that newly created agents automatically get an Entra agent identity, manageable in the Entra admin center, and identity activity is logged in Entra. That solves who the agent is and improves identity governance visibility. But multi-agent deployments introduce a new risk class: Autonomous execution sprawl — many agents, operating with delegated privileges, invoking the same backends independently. OAuth and API permissions answer “can the agent call this API?” They do not answer “should the agent execute this action under business policy, compliance constraints, data boundaries, and approval thresholds?” This is where a runtime authorization decision plane becomes essential. The pattern: Microsoft Entra‑Protected Authorization Fabric (PEP + PDP) Instead of embedding RBAC logic independently inside every agent, use a shared fabric: PEP (Policy Enforcement Point): Gatekeeper invoked before any tool/action PDP (Policy Decision Point): Evaluates RBAC + ABAC + approval policies Decision output: ALLOW / DENY / REQUIRE_APPROVAL / MASK This Authorization Fabric functions as a shared enterprise control plane, decoupling authorization logic from individual agents and enforcing policies consistently across all autonomous execution paths. Architecture (POC reference architecture) Use a single runtime decision plane that sits between agents and tools. What’s important here Every agent (Copilot Studio or AI Foundry/SK) calls the Authorization Fabric API first The fabric is a protected endpoint (Microsoft Entra‑protected endpoint required) Tools (Graph/ERP/CRM/custom APIs) are invoked only after an ALLOW decision (or approval) Trust boundaries enforced by this architecture Agents never call business tools directly without a prior authorization decision The Authorization Fabric validates caller identity via Microsoft Entra Authorization decisions are centralized, consistent, and auditable Approval workflows act as a runtime “break-glass” control for high-impact actions This ensures identity, intent, and execution are independently enforced, rather than implicitly trusted. Runtime flow (Decision → Approval → Execution) Here is the runtime sequence as a simple flow (you can keep your Mermaid diagram too). ```mermaid flowchart TD START(["START"]) --> S1["[1] User Request"] S1 --> S2["[2] Agent Extracts Intent\n(action, resource, attributes)"] S2 --> S3["[3] Call /authorize\n(Entra protected)"] S3 --> S4 subgraph S4["[4] PDP Evaluation"] ABAC["ABAC: Tenant · Region · Data Sensitivity"] RBAC["RBAC: Entitlement Check"] Threshold["Approval Threshold"] ABAC --> RBAC --> Threshold end S4 --> Decision{"[5] Decision?"} Decision -->|"ALLOW"| Exec["Execute Tool / API"] Decision -->|"MASK"| Masked["Execute with Masked Data"] Decision -->|"DENY"| Block["Block Request"] Decision -->|"REQUIRE_APPROVAL"| Approve{"[6] Approval Flow"} Approve -->|"Approved"| Exec Approve -->|"Rejected"| Block Exec --> Audit["[7] Audit & Telemetry"] Masked --> Audit Block --> Audit Audit --> ENDNODE(["END"]) style START fill:#4A90D9,stroke:#333,color:#fff style ENDNODE fill:#4A90D9,stroke:#333,color:#fff style S1 fill:#5B5FC7,stroke:#333,color:#fff style S2 fill:#5B5FC7,stroke:#333,color:#fff style S3 fill:#E8A838,stroke:#333,color:#fff style S4 fill:#FFF3E0,stroke:#E8A838,stroke-width:2px style ABAC fill:#FCE4B2,stroke:#999 style RBAC fill:#FCE4B2,stroke:#999 style Threshold fill:#FCE4B2,stroke:#999 style Decision fill:#fff,stroke:#333 style Exec fill:#2ECC71,stroke:#333,color:#fff style Masked fill:#27AE60,stroke:#333,color:#fff style Block fill:#C0392B,stroke:#333,color:#fff style Approve fill:#F39C12,stroke:#333,color:#fff style Audit fill:#3498DB,stroke:#333,color:#fff ``` Design principle: No tool execution occurs until the Authorization Fabric returns ALLOW or REQUIRE_APPROVAL is satisfied via an approval workflow. Where Power Automate fits (important for readers) In most Copilot Studio implementations, Agents calls Power Automate (agent flows), is the practical integration layer that calls enterprise services and APIs. Copilot Studio supports “agent flows” as a way to extend agent capabilities with low-code workflows. For this pattern, Power Automate typically: acquires/uses the right identity context for the call (depending on your tenant setup), and calls the /authorize endpoint of the Authorization Fabric, returns the decision payload to the agent for branching. Copilot Studio also supports calling REST endpoints directly using the HTTP Request node, including passing headers such as Authorization: Bearer <token>. Protected endpoint only: Securing the Authorization Fabric with Microsoft Entra For this V2 pattern, the Authorization Fabric must be protected using Microsoft Entra‑protected endpoint on Azure Functions/App Service (built‑in auth). Microsoft Learn provides the configuration guidance for enabling Microsoft Entra as the authentication provider for Azure App Service / Azure Functions. Step 1 — Create the Authorization Fabric API (Azure Function) Expose an authorization endpoint: HTTP Step 2 — Enable Microsoft Entra‑protected endpoint on the Function App In Azure Portal: Function App → Authentication Add identity provider → Microsoft Choose Workforce configuration (enterprise tenant) Set Require authentication for all requests This ensures the Authorization Fabric is not callable without a valid Entra token. Step 3 — Optional hardening (recommended) Depending on enterprise posture, layer: IP restrictions / Private endpoints APIM in front of the Function for rate limiting, request normalization, centralized logging (For a POC, keep it minimal—add hardening incrementally.) Externalizing policy (so governance scales) To make this pattern reusable across multiple agents, policies should not be hardcoded inside each agent. Instead, store policy definitions in a central policy store such as Cosmos DB (or equivalent configuration store), and have the PDP load/evaluate policies at runtime. Why this matters: Policy changes apply across all agents instantly (no agent republish) Central governance + versioning + rollback becomes possible Audit and reporting become consistent across environments (For the POC, a single JSON document per policy pack in Cosmos DB is sufficient. For production, add versioning and staged rollout.) Store one PolicyPack JSON document per environment (dev/test/prod). Include version, effectiveFrom, priority for safe rollout/rollback. Minimal decision contract (standard request / response) To keep the fabric reusable across agents, standardize the request payload. Request payload (example) Decision response (deterministic) Example scenario (1 minute to understand) Scenario: A user asks a Finance agent to create a Purchase Order for 70,000. Even if the user has API permission and the agent can technically call the ERP API, runtime policy should return: REQUIRE_APPROVAL (threshold exceeded) trigger an approval workflow execute only after approval is granted This is the difference between API access and authorized business execution. Sample Policy Model (RBAC + ABAC + Approval) This POC policy model intentionally stays simple while demonstrating both coarse and fine-grained governance. 1) Coarse‑grained RBAC (roles → actions) FinanceAnalyst CreatePO up to 50,000 ViewVendor FinanceManager CreatePO up to 100,000 and/or approve higher spend 2) Fine‑grained ABAC (conditions at runtime) ABAC evaluates context such as region, classification, tenant boundary, and risk: 3) Approval injection (Agent‑level JIT execution) For higher-risk/high-impact actions, the fabric returns REQUIRE_APPROVAL rather than hard deny (when appropriate): How policies should be evaluated (deterministic order) To ensure predictable and auditable behavior, evaluate in a deterministic order: Tenant isolation & residency (ABAC hard deny first) Classification rules (deny or mask) RBAC entitlement validation Threshold/risk evaluation Approval injection (JIT step-up) This prevents approval workflows from bypassing foundational security boundaries such as tenant isolation or data sovereignty. Copilot Studio integration (enforcing runtime authorization) Copilot Studio can call external REST APIs using the HTTP Request node, including passing headers such as Authorization: Bearer <token> and binding response schema for branching logic. Copilot Studio also supports using flows with agents (“agent flows”) to extend capabilities and orchestrate actions. Option A (Recommended): Copilot Studio → Agent Flow (Power Automate) → Authorization Fabric Why: Flows are a practical place to handle token acquisition patterns, approval orchestration, and standardized logging. Topic flow: Extract user intent + parameters Call an agent flow that: calls /authorize returns decision payload Branch in the topic: If ALLOW → proceed to tool call If REQUIRE_APPROVAL → trigger approval flow; proceed only if approved If DENY → stop and explain policy reason Important: Tool execution must never be reachable through an alternate topic path that bypasses the authorization check. Option B: Direct HTTP Request node to Authorization Fabric Use the Send HTTP request node to call the authorization endpoint and branch using the response schema. This approach is clean, but token acquisition and secure secretless authentication are often simpler when handled via a managed integration layer (flow + connector). AI Foundry / Semantic Kernel integration (tool invocation gate) For Foundry/SK agents, the integration point is before tool execution. Semantic Kernel supports Azure AI agent patterns and tool integration, making it a natural place to enforce a pre-tool authorization check. Pseudo-pattern: Agent extracts intent + context Calls Authorization Fabric Enforces decision Executes tool only when allowed (or after approval) Telemetry & audit (what Security Architects will ask for) Even the best policy engine is incomplete without audit trails. At minimum, log: agentId, userUPN, action, resource decision + reason + policyIds approval outcome (if any) correlationId for downstream tool execution Why it matters: you now have a defensible answer to: “Why did an autonomous agent execute this action?” Security signal bonus: Denials, unusual approval rates, and repeated policy mismatches can also indicate prompt injection attempts, mis-scoped agents, or governance drift. What this enables (and why it scales) With a shared Authorization Fabric: Avoid duplicating authorization logic across agents Standardize decisions across Copilot Studio + Foundry agents Update governance once (policy change) and apply everywhere Make autonomy safer without blocking productivity Closing: Identity gets you who. Runtime authorization gets you whether/when/how. Copilot Studio can automatically create Entra agent identities (preview), improving identity governance and visibility for agents. But safe autonomy requires a runtime decision plane. Securing that plane as an Entra-protected endpoint is foundational for enterprise deployments. In enterprise environments, autonomous execution without runtime authorization is equivalent to privileged access without PIM—powerful, fast, and operationally risky.Unanswered Questions on GitHub Copilot Harness in Copilot Studio
We're piloting the GitHub Copilot harness in Copilot Studio (GA August 2026) and several operational and architectural details remain undocumented in the GA FAQ, Microsoft Learn, or licensing guides. Looking for official answers or PM contacts on: Architecture & Execution – When the harness breaks tasks into subtasks, does it use internal sub-agents or only skills/connected agents, what are the exact timeout/retry/max-execution-duration limits for long-running workflows, and are planning/context-retrieval/orchestration internals documented anywhere or is the orchestrator a black box? Model Selection – Can individual skills within one agent use different models or is selection strictly agent-level, how are models chosen internally when multiple skills execute, are any internal models developer-configurable, and what's the roadmap for models being added/retired/deprecated plus the lag between public release and Copilot Studio availability? Cost & Token Optimization – How exactly is the ~45% token reduction achieved, how much control do makers have over context/caching/retrieval/tool calls, what are per-model credit consumption characteristics, which models are most cost-effective for specific workloads, and what's the minimum credit cost for trivial interactions? Memory Management – What are retention periods for session/working/agent memory beyond the documented 28-day user-memory expiry, is true long-term memory supported, and what changed versus earlier implementations? Knowledge Retrieval – Can skills or system instructions influence retrieval strategy/document selection/prioritization/filtering, can planning stages perform conflict/duplicate/version detection before retrieval, and how does the harness decide which sources to search? Apps Feature – What is the "Apps (preview)" capability for, when does it GA, and how does it differ from workflows/skills/adaptive cards/agents? Billing & Credit Sizing – Is there a framework to classify users/agents by expected consumption and size credit allocation per group (citizen vs pro developers), and what's the minimum/typical consumption for simple/medium/heavy interactions? Governance & Admin – Can usage limits be set at user level (not just environment/agent), is there an API/IaC path for large-scale credit assignment, can non-admins view their own consumption/remaining allocation, and is there a self-service request-more-credits dashboard? ALM & Environments – What's the recommended path to move harness agents across Dev/Test/UAT/Prod (Solutions/ALM "setup differs" per parity chart—how?), does GitHub integration replace or complement solution-based deployment, are there recommended AgentOps practices for source control/releases/versioning, and what baseline credits and onboarding model are suggested for citizen developers under usage billing—any enterprise reference implementations?MCP safety & evaluation with the Agent 365 CLI & Agent Governance Toolkit
Co Author: JiteshThakur AI agents are useful because they can act. They call tools, query databases, send messages, and hand work to other agents. That same freedom creates a problem: access control can tell you which service an agent may reach, but it does not always tell you whether a particular action is sensible, safe, or permitted. MCP is how most agents now act. Two Control Points: This post examines two control points that address different parts of the MCP lifecycle. Agent 365 CLI evaluates the MCP server before an agent uses it. Agent Governance Toolkit (AGT) governs sensitive tool calls while the agent runs. One improves what the agent sees. The other governs what the agent does. The Agent 365 CLI is a cross-platform command-line tool for Agent 365 applications on Azure. Its evaluation command examines MCP tool definitions and scores their quality. AGT evaluates actions against policy and records each decision. Together, these tools support a practical model: evaluate the server first, then provide proper scaffolding for the developer to test this in a dry run. Agent 365 CLI: Score an MCP server from the command line: The Agent 365 CLI can evaluate an MCP server against research-based practices for production readiness. The result is more useful than a simple pass or fail. The evaluation gives you: A score for each tool name, description, and parameter schema; A prioritized list of improvements; An overall maturity score for the server; and Local output that you can use early in development. This report turns a vague question, "Is this MCP server ready?", into a concrete list of work. The evaluate command a365 develop-mcp evaluate --server-url <server-url> [--auth-token <auth-token>] [options] The command reads the tool schemas from the server. It then produces guidance for names, descriptions, parameters, and schema structure. A local coding-agent CLI scores the semantic checks. You can use GitHub Copilot CLI or Claude Code under your account and AI subscription. The command does not send tool-schema data to Microsoft. Prerequisites: Install the following software: Agent 365 CLI; Node.js 18 or later for GitHub Copilot CLI; and A supported coding-agent CLI for semantic scoring. For example, install GitHub Copilot CLI with this command: powershell npm install -g @github/copilot This bring-your-own-LLM model keeps the scoring step in your local development environment. It is useful when model calls must remain inside an approved deployment. How the evaluation works The command runs a five-step pipeline and logs progress as it goes. Fig 1: MCP Evaluation using Agent 365 Cli Connect to the MCP server and collect its tool schemas. Generate an evaluation checklist in the output directory. Score the semantic checks with the selected coding agent. Calculate the maturity level and action priorities. Write the JSON and HTML reports. The evaluation contains two types of checks: Deterministic checks use exact rules in the CLI. For example, a tool name cannot be empty. Semantic checks use a coding agent to score clarity and meaning. Each result includes a reason for the score. Examples Set the authentication token in an environment variable. Then evaluate an authenticated server and write the artifacts to a subfolder. powershell $env:A365_MCP_AUTH_TOKEN = "<bearer-token>" a365 develop-mcp evaluate --server-url "https://my-mcp-server.contoso.com/mcp" --output-dir "./eval" Use a specific scoring engine with the `--eval-engine` option: powershell a365 develop-mcp evaluate --server-url "http://localhost:5000/mcp" --eval-engine claude-code Scenario: Evaluate a malicious MCP server For this demonstration, we hosted a deliberately malicious MCP server at `http://127.0.0.1:8124/`. It exposes tools that demonstrate tool poisoning, credential leakage, prompt injection, schema mismatch, sandbox escape, and other attacks. The server is intentionally unsafe and is for demonstration only. Fig 2: Setting up a test MCP server for evaluation We ran the evaluation in two steps. First, we generated the checklist without automatic semantic scoring: a365 develop-mcp evaluate --server-url "http://127.0.0.1:8124/" --eval-engine none Fig 3: Agent365CLI MCP Evaluation The command wrote the checklist and a semantic-evaluation prompt to the output directory. It also displayed the next steps. Second, we gave the prompt and checklist to a coding agent. The agent completed each unscored semantic check with a Boolean score and a short reason. After we saved the completed checklist, we ran the command again to generate the report: a365 develop-mcp evaluate --server-url "http://127.0.0.1:8124/" --output-dir "C:\temp\MaliciousMCP" Fig 4: Creating the report with Agent365 CLI MCP Evaluate command Understanding the evaluation report Open `<server-name>_eval_report.html` from the output directory. The report contains: The overall score from 0 to 100; The maturity level from 0 to 4; Scores for each tool and quality category; and A prioritized action list for the next maturity level. Fig 5: MCP Evaluation Report In our demonstration, the server scored 86.0 and reached Level 3: Optimized for AI. That strong overall score did not mean that every tool was safe or clear. The report found 58 action items, including one critical item and 33 high-priority items. That contrast matters. A server can have valid schemas and consistent names while still exposing misleading or dangerous tools. Fig 6: MCP Evaluation Report - Tool-By-Tool Detail What to look for Read the per-tool results before the overall score. A single weak tool can create more risk than the server average suggests. Focus on these report sections: Tool names: Can an agent select the correct tool from its name? Tool descriptions: Does each description explain the purpose and correct use? Parameter names: Do the names identify the data that the tool requires? Parameter descriptions: Do they explain the format, type, and constraints? Schema structure: Are the schemas valid and processable? Action items: Which changes have the highest effect on tool selection and use? The command processes static tool schemas from `tools/list`. It does not process runtime payloads, end-user data, or personal data. The command keeps the `--auth-token` value in memory. It sends the value only in the HTTP `Authorization` header. It does not write the token to disk or give it to the coding agent. AGT: Put governance in the execution path: Microsoft's open-source Agent Governance Toolkit (AGT) evaluates an action before execution. It adds identity and policy context, records the decision, and can send risky work for approval. This can be used by developers during the build time for dynamic evaluation of the MCP server. AGT lets developers put part of that intent into the execution path. Remote tools still need secure implementations, sandboxes need hard boundaries, and audit records need appropriate storage and access controls. You do not need to replace your agent framework to use it. What sits in the decision path? AGT wraps the tools that an agent already uses. You can start to govern a tool with two lines of Python: python from agentmesh.governance import govern safe_tool = govern(my_tool, policy="policy.yaml") On each call, `safe_tool` evaluates the configured policy. An allowed action reaches the original tool. A denied action raises `GovernanceDenied` and creates a decision record. This wrapper model reduces the cost of adoption. Teams can add governance to an existing agent stack without rebuilding it. AGT supports Python, TypeScript, .NET, Rust, and Go. Its documented integrations include popular agent frameworks, MCP, and A2A. Teams can also adopt AGT in stages. A team can begin with policy checks and audit records. It can add identity, approvals, sandboxing, and operational controls as risk increases. Each control answers a different question: Policy: Is this action allowed? Identity and trust: Which agent made the request? Runtime controls: What limits apply to execution? Audit evidence: Why did AGT allow or deny the action? A low-risk assistant can need only a deny rule and basic logging. An agent that moves money or changes production systems needs stronger controls. Fig 7: AGT Architecture Scenario: Govern the same malicious MCP server For this scenario demonstration, we used AGT Python packages as an MCP gateway. The gateway sat between an agent and the same malicious server from the earlier evaluation. This setup let us examine both control points against one target. The Agent 365 CLI examined the server's static tool definitions. The AGT gateway examined real requests and responses for the developer during its testing. Fig 8: AGT findings at runtime In the policy interface, a developer can edit runtime limits and detection rules. The developer can also validate the policy against sample tool metadata, save a revision, and activate it with a recorded reason. Fig 9: AGT control coverage The control-coverage view shows which AGT capabilities are active in the gateway. It also links each capability to package checks and end-to-end evidence. In our demonstration, we included the following controls: Tool metadata poisoning detection; Tool change and rug-pull detection; Dangerous argument blocking; Tool-response content scanning; Per-client tool-call budgets; and A redacted decision audit trail. You can build your detection & input security by reading more about it here. The gateway detected malicious content. For one blocked `tools/list` request, it recorded the findings. The important result was not only that AGT blocked the request. It also preserved the matched evidence, affected tool locations, policy modes, and request context. Fig 10: Example detection via AGT The dashboard then summarized block-mode findings, leading risk drivers, and tools that required review. This evidence can help a team prioritize policy changes and investigate repeated attacks. Fig 11: Sample AGT metrics AGT does not require this UI, gateway, or architecture. Its structured decisions can feed an admin console, SIEM, incident workflow, or approval queue. AGT also includes an Agent Compliance package with mappings for OWASP and other controls. These mappings give developers and governance teams a common record of applied controls. Teams do not need to reconstruct the agent's behavior after an incident. Check Compliance - Agent Governance Toolkit for more information. Conclusion: MCP safety needs controls before and during execution. The Agent 365 CLI improves the MCP interface before deployment. It exposes unclear tool definitions, scores server maturity, and turns quality gaps into prioritized work. While AGT is implemented at the build phase, it provides developers the ability to test policy, identity, execution context & preserve evidence for allowed or denied decisions. Neither tool replaces secure server code, strong sandbox boundaries, or protected audit storage. Instead, they make those controls easier to evaluate and explain. Start with one MCP server and one consequential tool call. Evaluate the server with the Agent 365 CLI. Then put an AGT policy around the action that carries the most risk. While these controls help secure the build phase of an agent, once agents move into production, runtime controls become essential. Agent365 provides those controls at runtime.

Why is this needed? Sensitivity labels are generally relevant within an organisation only. If a file is labelled within one environment and then moved to another environment, sensitivity label content markings may be visible, but by default, the applied sensitivity label will not be understood. This can lead to scenarios where information that has been generated externally is not adequately protected. My favourite analogy for these scenarios is to consider the parallels between receiving sensitive information and unpacking groceries. When unpacking groceries, you might sit your grocery bag on a counter or on the floor next to the pantry. You’ll likely then unpack each item, take a look at it and then decide where to place it. Without looking at an item to determine its correct location, you might place it in the wrong location. Porridge might be safe from the kids on the bottom shelf. If you place items that need to be protected, such as chocolate, on the bottom shelf, it’s not likely to last very long. So, I affectionately refer to information that hasn’t been evaluated as ‘porridge’, as until it has been checked, it will end up on the bottom shelf of the pantry where it is quite accessible. Label-based security controls, such as Data Loss Prevention (DLP) policies using conditions of ‘content contains sensitivity label’ will not apply to these items. To ensure the security of any contained sensitive information, we should look for potential clues to its sensitivity and then utilize these clues to ensure that the contained information is adequately protected - We take a closer look at the ‘porridge’, determine whether it’s an item that needs protection and if so, move it to a higher shelf in the pantry so that it’s out of reach for the kids. Effective use of Purview revolves around the use of ‘know your data’ strategies. We should be using as many methods as possible to try to determine the sensitivity of items. This can include the use of Sensitive Information Types (SITs) containing keyword or pattern-based classifiers, trainable classifiers, Exact Data Match, Document fingerprinting, etc. Matching items via SITs present in the items content can be problematic due to false positives. Keywords like ‘Sensitive’ or ‘Protected’ may be mentioned out of context, such as when referring to a classification or an environment. When classifications have been stamped via a property, it allows us to match via context rather than content. We don’t need to guess at an item’s sensitivity if another system has already established what the item’s classification is. These methods are much less prone to false positives. Why isn’t everyone doing this? Document properties are often not considered in Purview deployments. SharePoint metadata management seems to be a dying artform and most compliance or security resources completing Purview configurations don’t have this skill set. There’s also a lack of understanding of the relevance of checking for item properties. Microsoft haven’t helped as the documentation in this space is somewhat lacking and needs to be unpicked via some aligning DLP guidance (Create a DLP policy to protect documents with FCI or other properties). Many of these configurations will also be tied to regional requirements. Document properties being used by systems where I’m from, in Australia, will likely be very different to those used in other parts of the world. In the following sections, we’ll take a look at applicable use cases and walk through how to enable these configurations. Scenarios for use Labelling via document property isn’t for everyone. If your organisation is new to classification or you don’t have external partners that you collaborate with at higher sensitivity levels, then this likely isn’t for you. For those that collaborate heavily and have a shared classification framework, as is often seen across government, this is a must! This approach will also be highly relevant to multi-tenant organisations or conglomerates where information is regularly shared between environments. The following scenarios are examples of where this configuration will be relevant: 1. Migrating from 3 rd party classification tools If an item has been previously stamped by a 3 rd party classification tool, then evaluating its applied document properties will provide a clear picture of its security classification. These properties can then be used in service-based auto-labelling policies to effectively transition items from 3 rd party tools to Microsoft Purview sensitivity labels. As labels are applied to items, they will be brought into scope of label-based controls. 2. Detecting data spill Data spill is a term that is used to define situations where information that is of a higher than permitted security classification land in an environment. Consider a Microsoft 365 tenant that is approved for the storage of Official information but Top Secret files are uploaded to it. Document properties that align with higher than permitted classifications provide us with an almost guaranteed method of identifying spilled items. Pairing this document property with an auto-labelling policy allows for the application of encryption to lock unauthorized users out of the items. Tools like Content Explorer and eDiscovery can then be used to easily perform cleanup activities. If using document properties and auto-labelling for this purpose, keep in mind that you’ll need to create sensitivity labels for higher than permitted classifications in order to catch spilled items. These labels won’t impact usability as you won’t publish them to users. You will, however, need to publish them to a single user or break glass account so that they’re not ignored by auto-labelling. 3. Blocking access by AI tools If your organization was concerned about items with certain properties applied being accessed by generative AI tools, such as Copilot, you could use Auto-labelling to apply a sensitivity label that restricts EXTRACT permissions. You can find some information on this at Microsoft 365 Copilot data protection architecture | Microsoft Learn. This should be relevant for spilled data, but might also be useful in situations where there are certain records that have been marked via properties and which should not be Copilot accessible. 4. External Microsoft Purview Configurations Sensitivity labels are relevant internally only. A label, in its raw form, is essentially a piece of metadata with an ID (or GUID) that we stamp on pieces of information. These GUIDs are understood by your tenant only. If an item marked with a GUID shows up in another Microsoft 365 tenant, the GUID won’t correspond with any of that tenant’s labels or label-based controls. The art in Microsoft Purview lies in interpreting the sensitivity of items based on content markings and other identifiers, so that data security can be maintained. Document properties applied by Purview, such as ClassificationContentMarkingHeaderText are not relevant to a specific tenant, which makes them portable. We can use these properties to help maintain classifications as items move between environments. 5. Utilizing metadata applied by Records Management solutions Some EDRMS, Records or Content Management solutions will apply properties to items. If an item has been previously managed and then stamped with properties, potentially including a security classification, via one of these systems, we could use this information to inform sensitivity label application. 6. 3 rd party classification tools used externally Even if your organisation hasn’t been using 3rd party classification tools, you should consider that partner organisations, such as other Government departments, might be. Evaluating the properties applied by external organisations to items that you receive will allow you to extend protections to these items. If classification tools like Janus or Titus are used in your geography/industry, then you may want to consider checking for their properties. Regarding the use of auto-classification tools Some organisations, particularly those in Government, will have organisational policies that prevent the use of automatic classification capabilities. These policies are intended to ensure that each item is assessed by an actual person for risk of disclosure rather than via an automated service that could be prone to error. However, when auto-labelling is used to interpret and honour existing classifications, we are lowering rather than raising the risk profile. If the item’s existing classification (applied via property) is ignored, the item will be treated as porridge and is likely to be at risk. If auto-labelling is able to identify a high-risk item and apply the relevant label, it will then be within scope of Purview’s data security controls, including label-based DLP, groups and sites data out of place alerting, and potentially even item encryption. The outcome is that, through the use of auto-labelling, we are able to significantly reduce risk of inappropriate or unintended disclosure. Configuration Process Setting up document property-based auto-labelling is fairly straightforward. We need to setup a managed property and then utilize it an auto-labelling policy. Below, I've split this process into 6 steps: Step 1 – Prepare your files In order to make use of document properties, an item with the properties applied will first need to be indexed by SharePoint. SharePoint will record the properties as ‘crawled properties’, which we’ll then need to convert into ‘managed properties’ to make them useful. If you already have items with the relevant properties stored in SharePoint, then they are likely already indexed. If not, you’ll need to upload or create an item or items with the properties applied. For testing, you’ll want to create a file with each property/value combination so that you can confirm that your auto-labelling policies are all working correctly. This could require quite a few files depending on the number of properties you’re looking for. To kick off your crawled property generation though, you could create or upload a single file with the correct properties applied. For example: In the above, I’ve created properties for ClassificationContentMarkingHeaderText and ClassificationContentMarkingFooterText, which you’ll often see applied by Purview when an item has a sensitivity label content marking applied to it. I’ve also included properties to help identify items classified via JanusSeal, Titus and Objective. Step 2 – Index the files After creating or uploading your file, we then need SharePoint to index it. This should happen fairly quickly depending on the size of your environment. I'd expect to wait sometime between 10 minutes and 24 hrs. If you're not in a hurry, then I'd recommend just checking back the next day. You'll know when this has been completed when you head into SharePoint Admin > Search > Managed Search Schema > Crawled Properties and can find your newly indexed properties: Step 3 – Configure managed properties Next, the properties need to be configured as managed properties. To do this, go to SharePoint Admin > More features > Search > Managed Search Schema > Managed Properties. Create a new managed property and give it a name. Note that there are some character restrictions in naming, but you should be able to get it close to your document property name. Set the property’s type to text, select queryable and retrievable. Under ‘mappings to crawled properties’, choose add mapping, search for and select the property indexed from the file property. Note that the crawled property will have the same name as your document property, so there’s no need to browse through all of them: Repeat this so that you have a managed property for each document property that you want to look for. Step 4 – Configure Auto-labelling policies Next up, create some auto-labelling policies. You’ll need one for each label that you want to apply, not one per property as you can check multiple properties within the one auto-labelling policy. - From within Purview, head to Information Protection > Policies > Auto-labelling policies. - Create a new policy using the custom policy template. - Give your policy an appropriate name (e.g. Label PROTECTED via property). - Select the label that you want to apply (e.g. PROTECTED). - Select SharePoint based services (SharePoint and OneDrive). - Name your auto-labelling rules appropriately (e.g. SPO – Contains PROTECTED property) - Enter your conditions as a long string with property and value separated via a colon and multiple entries separated with a comma. For example: ClassificationContentMarkingHeaderText:PROTECTED,ClassificationContentMarkingFooterText:PROTECTED,Objective-Classification:PROTECTED,PMDisplay:PROTECTED,TitusSEC:PROTECTED Note that the properties that you are referencing are the Managed Property rather than the document property. This will be relevant if your managed property ended up having a different name due to character restrictions. After pasting in your string into the UI, the resultant rule should look something like this: When done, you can either leave your policy in simulation mode or save it and then turn it on from the auto-labelling policies screen. Just be aware of any potential impacts, such as accidently locking users out by automatically deploying a label with encryption configuration. You can reduce any potential impact by targeting your auto-labelling policy at a site or set of sites initially and then expanding its scope after testing. Step 5 - Test Testing your configuration will be as easy as uploading or creating a set of files with the relevant document properties in place. Once uploaded, you’ll need to give SharePoint some time to index the items and then the auto-labelling policy some time to apply sensitivity labels to them. To confirm label application, you can head to the document library where your test files are located and enable the sensitivity column. Files that have been auto-labelled will have their label listed: You could also check for auto-labelling activity in Purview via Activity explorer: Step 6 – Expand into DLP If you’ve spent the time setting up managed properties, then you really should consider capitalizing on them in your DLP configurations. DLP policy conditions can be configured in the same manner that we configured Auto-labelling in Step 3 above. The document property also gives us an anchor for DLP conditions that is independent of an item’s sensitivity label. You may wish to consider the following: DLP policies blocking external sharing of items with certain properties applied. This might be handy for situations where auto-labelling hasn’t yet labelled an item. DLP policies blocking the external sharing of items where the applied sensitivity label doesn’t match the applied document property. This could provide an indication of risky label downgrade. You could extend such policies into Insider Risk Management (IRM) by creating IRM policies that are aligned with the above DLP policies. This will allow for document properties to be considered in user risk calculation, which can inform controls like Adaptive Protection. Here's an example of a policy from the DLP rule summary screen that shows conditions of item contains a label or one of our configured document properties: Thanks for reading and I hope this article has been of use.

Proactive Reliability Series — Article 2: Regional Distribution Patterns for Azure Workloads
Introduction Public cloud platforms — including Microsoft Azure — are built on three foundational principles that distinguish them from traditional on-premises infrastructure: Elasticity: The platform can automatically expand and contract resource capacity in response to demand. Capacity is not statically provisioned; it is drawn from a shared pool and released when no longer needed. Scaling: Workloads can scale horizontally (adding more instances) or vertically (increasing instance size) on demand, without pre-procurement of physical hardware. Consumption-based billing: Customers pay for what they use, when they use it. Cost is proportional to resource consumption, not to physical capacity reserved in advance. These principles are properties of the platform, not of any single location. Microsoft Azure Cloud is not a single region — it is a globally distributed platform comprising dozens of regions across every major geography, interconnected by a private backbone network. When an organisation deploys to Azure, it is deploying into this global system; the choice of which region or regions to use is based on an organizational strategy and architectural decision. Using a single Azure region is a valid choice in many scenarios, but it has to be a deliberate architecture decision, not an omission. Why multi-region? Microsoft Azure CTO Mark Russinovich summarises the case for multi-region in Achieve agility and scale in a dynamic cloud world: organisations that span multiple regions gain scalability and flexibility (choosing from the full Azure region portfolio, including differentiated pricing, AI capabilities, and deployment options), resilience and availability (reducing the impact of regional disruptions through multiple backup and recovery options), and performance and reduced latency (serving users from infrastructure that is geographically closer to them). The post's closing recommendation — "leverage Azure as a cloud platform, not a datacenter region" — makes explicit what the multi-region decision ultimately is: a choice to treat the platform's global footprint as an asset, not a constraint. Mark Russinovich — Achieve agility and scale in a dynamic cloud world (Microsoft Azure, September 2024) This article also does not argue whether to adopt a multi-region strategy — that is a business and risk decision. It describes what the options are: the available regional distribution patterns, the forces each resolves, and the trade-offs each accepts. Regional workload distribution is not simply an application-level decision — it is an organisational one. It shapes how a company scales its cloud presence, manages cost and operational complexity across a growing portfolio, meets data residency and regulatory obligations, and positions itself to respond to changing conditions. Multi-region is often a necessity, not a free choice: growth ambitions, compliance requirements, or risk obligations may demand it. But necessity does not determine form. These patterns define the decision space: whether operating across multiple regions is warranted at all, and if so, which structural arrangement fits the organisation's scale, objectives, and operational capability. Several patterns are adapted from Gregor Hohpe's multi-cloud strategy patterns, originally described in Multi Cloud Architecture: Decisions and Options and further elaborated in Multi-cloud: From Buzzword to Decision Model. Note: This is an unofficial guide to regional distribution patterns for Azure workloads. It is not an official Microsoft publication and is not officially supported, endorsed, or maintained by Microsoft. All descriptions and recommendations are based on publicly available Azure documentation and general distributed systems principles. Always refer to official Azure documentation and the Azure Well-Architected Framework for authoritative guidance. The risks and opportunities Pattern selection is a direct response to specific risks or solution quality requirements. Before evaluating patterns (options), it is necessary to understand what risks are actually relevant — infrastructure faults, capacity constraints, service coverage gaps, and compliance or business obligations — and what their scope of impact is. Azure infrastructure is complex and distributed. While Microsoft invests heavily in reliability, faults can and do occur across a wide range of blast radii — from a single compute instance at the narrowest end, through Availability Zone and regional failures, to global service disruptions at the widest. The appropriate pattern is the one that reduces unacceptable risks to a tolerable level. The Azure Well-Architected Framework — Reliability pillar recommends Failure Mode Analysis (FMA) as the structured technique for enumerating failure modes, assessing their impact, and identifying mitigations before they are needed in production. The fault types below are the infrastructure-layer inputs to that analysis. For a detailed breakdown of each fault type — including likelihood analysis, real-world incident examples, and detection guidance — see Proactive Reliability Series — Article 1: Fault Types in Azure. Risk catalog (sample) The following is a representative sample of risks relevant to regional workload distribution decisions, not an exhaustive catalogue. Not all entries are infrastructure faults — some represent business and compliance obligations. The Category column identifies the type of each risk. Likelihood values are relative planning heuristics to help prioritise resilience investments — they are not statistical probabilities and do not represent Azure SLA commitments. Risk Category Blast Radius Likelihood Primary Mitigation Service Fault (Region) Infrastructure Fault Single service within a region Medium Region redundancy Region Fault Infrastructure Fault Regional degradation or full regional loss (partial-to-full region impact) Low Region redundancy; cross-region failover Network POP Location Fault Infrastructure Fault Network colocation site (affects connectivity, not compute) Low ExpressRoute Metro (dual peering locations); network path redundancy Service Fault (Global) Infrastructure Fault Worldwide or multiple regions simultaneously Very Low Accept risk; use alternative service if downtime is intolerable Regional Service Capacity Constraint Infrastructure Capacity Single region (required capacity unavailable — whole service or specific SKU — at failover time or sustained shortage) Low Region redundancy; Capacity Reservations; Hot Standby; alternative region Service Regional Unavailability Infrastructure Fault Single region (desired service not offered in that region) Low Deploy to a region where the service is available Geopolitical Risk Compliance One or more regions (regulatory or political mandate to relocate) Low Portable pattern; pre-validated alternative region Sustainability Constraint Compliance One or more regions (sustainability targets unachievable in current region) Low Portable pattern; relocate to region with required sustainability profile The patterns While there could be many ways to distribute workloads across Azure regions, the following patterns represent the most common and widely applicable approaches. Each pattern is a structural topology that defines how workloads are deployed and how they respond to Risks and Quality Requirements. The patterns are not mutually exclusive — they can be combined or layered to meet specific requirements. The following patterns describe the principal ways workloads can be distributed across Azure regions. Patterns 1-3 are described and found very often, while patterns 4-5 are less common but still important to consider. The table below summarises the patterns, their intent, and the primary driver for their adoption. # Pattern Intent Primary Driver 1 Single All resources in one Azure region; AZ redundancy optional Simplicity; cost; data residency constraints 2 Failover Primary region serves traffic; secondary region is a cold or hot standby for DR Business continuity 3 Parallel Same workload deployed to multiple regions simultaneously; all active Continuous availability; zero-downtime failover 4 Segmented Services or service portfolio distributed across regions by BU, LOB, tenant, or data residency Isolation; sovereignty; independent release cadence 5 Portable Full portability; workloads can be relocated between regions without application changes Operational flexibility; on-demand relocation 1. Single region pattern Pattern Name: Single Region Workload Distribution Classification: Regional workload distribution Scope: Workload — applies to a single application or service deployment, Workload (Application) Portfolio Intent: Deploy all workload resources in one Azure region. Context: A workload is being deployed to Azure and must decide how many regions to use. The business impact of a regional outage has been assessed — either as tolerable within the workload’s criticality tier, or as not applicable because data sovereignty constraints prohibit cross-region replication. The team needs to treat Single Region as an explicitly chosen architecture, not an omission. Problem: Every additional Azure region adds infrastructure cost and workload integration complexity due to the network latency it introduces. Not all workloads justify this overhead. The question is not “should I always use multiple regions?” but “when is a single region the correct and explicitly chosen answer, and when does adding a second region produce risk-reduction that justifies the cost?” Forces: The workload’s risk profile does not justify cross-region redundancy: the business impact of a regional outage is tolerable, data sovereignty rules prohibit cross-region replication, or reliability requirements are fully met within a single region with Availability Zone redundancy. The cost of multi-region infrastructure produces no corresponding risk-reduction return for this workload. Solution Place all compute, data, and networking resources in a single Azure region. Apply Availability Zone redundancy within that region for protection against datacenter-level failures. Formally accept region-level risk as within tolerance for this workload’s criticality tier — this is a deliberate architecture decision, not an omission. Implementation: Enable Availability Zones for all production resources where supported. Use Azure Infrastructure Resiliency Manager (AIRM) to validate zone-redundancy posture across the workload. Document the risk-acceptance decision explicitly at the application level. Consequences Benefits: Lowest cost and operational footprint of all patterns. No cross-region routing, replication lag, or failover coordination complexity. Simplest deployment pipeline, observability surface, and incident response. Liabilities: No mitigation for any region-level fault — full workload loss on regional failure. Data concentrated in one geography; no cross-region durability without explicit configuration. No pre-deployed capacity in an alternative region. Risk posture: Risk Assessment Region Fault ❌ Primary unaddressed risk — partial degradation or full regional failure has no cross-region recovery path; accept or upgrade pattern Service Fault (Region) ❌ Regional service failures have no cross-region alternative Regional Service Capacity Constraint ❌ No alternative region available; both on-demand failover provisioning and sustained SKU shortages have no mitigation path Network POP Location Fault ✅ Addressable within this pattern via ExpressRoute Metro (dual peering locations in the same metro); does not require a multi-region distribution change Known uses Development and test environments; Bronze- or Non-Critical-tier workloads; workloads with strict data residency constraints that prohibit cross-region replication; proof-of-concept and time-limited deployments. See Azure Services - Sample Multi-Region Capabilities Pattern Mapping for how individual Azure services implement this pattern.

Failover pattern (primary + standby region) Pattern Name: Failover Workload Distribution Also Known As: Active-Passive, Disaster Recovery (DR), Business Continuity and Disaster Recovery (BCDR) Classification: Regional workload distribution, Application Design, Platform/Infrastructure Design, Disaster Recovery Scope: Workload — an application and infrastructure design pattern that requires both layers to work in tandem; Workload (Application) Portfolio Intent: Recover from a regional disaster or other longer duration region outage by designating a primary region to carry all production traffic and a standby region to absorb that traffic upon primary region failure. The typical quality attribute metrics that govern its design are RTO (Recovery Time Objective — maximum tolerable downtime), RPO (Recovery Point Objective — maximum tolerable data loss), and MTTR (Mean Time To Recovery — the observed average recovery time, measured through drills and real incidents, that validates whether the RTO target is achievable in practice). Context: A workload must survive region-level failures, but the architectural complexity of running two fully active deployments simultaneously — with multi-region write-conflict resolution — is not justified. The business can tolerate a bounded recovery time and, depending on the sub-variant chosen, a bounded data loss window. Problem: A fully active multi-region deployment (Parallel pattern) introduces multi-region write-conflict complexity that the application cannot or need not absorb. The Failover pattern trades continuous availability for single-writer simplicity: one region is active, one is standby, and recovery is bounded by RTO/RPO targets. The sub-variant choice (Cold / Warm / Hot) then determines how much cost is invested in standby readiness — from minimal (~1.1×) to near-full duplication (~2×) — based on how fast recovery must be. Forces: A single active write region is required — multi-region write-conflict resolution adds unacceptable consistency risk or development complexity. RTO and RPO targets must be met, but budget constrains how pre-warmed the standby region can be, driving the Cold / Warm / Hot sub-variant selection. Regional Service Capacity Constraint in the standby region is a residual risk for Cold and Warm sub-variants — the standby may fail to scale at failover time unless capacity is pre-reserved. Solution Designate one region as primary (all production traffic under normal conditions) and a second as standby (no production traffic until failover). The standby’s readiness level — the sub-variant choice — is determined by the RTO/RPO requirements and cost envelope. Replication from primary to standby is continuous; failover is triggered manually or automatically when the primary becomes unavailable. Note on "Active-Passive": This pattern is often called Active-Passive in Microsoft documentation. That framing is accurate at the traffic level (one region active, one passive), but it can obscure the architectural intent. The Failover label here emphasises the capability being purchased: the ability to redirect the entire workload to a pre-designated region when the primary is unavailable. Implementation: The key design decision is how ready the standby is at the moment it is needed. Three sub-variants define this readiness spectrum: Sub-variant Secondary state Cost multiplier Cold Standby No running compute; data either in scheduled backups or continuously replicated ~1.1–1.5× Warm Standby Reduced-scale compute running; data continuously replicated ~1.5–1.8× Hot Standby Full-scale compute running; data continuously replicated ~2× Cold Standby — No compute is running in the standby region under normal conditions. Cold Standby covers two positions within this state, differing in how the data layer is protected: Backup/Restore: Data is backed up or geo-replicated on a scheduled basis. On failover, infrastructure must be deployed from scratch and data restored before traffic can be redirected. RTO is measured in hours; RPO equals the interval between the last backup cycle and the failure event. Data-layer live, compute stopped: Core infrastructure (networking, identity, data tier) is kept running with continuous replication to the standby region; compute is stopped or scaled to zero. On failover, compute is started and scaled up to meet full load. RTO is typically 15–60 minutes; RPO is bounded by async replication lag rather than backup interval. Both positions share the defining characteristic of Cold Standby: no production-equivalent compute running in the secondary region under normal conditions. The difference is the investment in keeping the data layer live, which reduces both RTO and the data loss window at a modestly higher steady-state cost. Warm Standby — The standby region runs a scaled-down but functionally complete version of the workload. Traffic is not routed there under normal conditions. On failover, the secondary scales up and traffic is redirected. A brief scale-out lag occurs before the secondary absorbs full traffic; the running environment eliminates cold-start delay. Hot Standby — The standby region runs a full, production-equivalent deployment — same compute capacity, same configuration — but receives no traffic under normal conditions. Data is continuously and near-synchronously replicated. Failover is fast and often automated because no scale-up is required. Consequences Benefits: Enables recovery from region-level faults at a fraction of Parallel pattern cost. Flexible cost-vs-RTO trade-off across Cold / Warm / Hot sub-variants. No multi-region write-conflict complexity; single active write region throughout normal and recovery operation. Liabilities: Cold and Warm standby introduce meaningful RTO (minutes to hours). Replication lag creates a data loss window (RPO > 0) at the moment of failover. The failover path is the least-exercised code path — untested recovery inflates actual RTO. Failover is often neglected and not properly and regularly tested — this leads to a fear of executing failover when needed (and not only a full-region disaster demands it). Risk posture: Risk Assessment Region Fault ⚠️ Primary driver; standby region absorbs traffic on full regional loss, but partial regional degradation may not trigger automated failover. RTO depends on sub-variant Regional Service Capacity Constraint ⚠️ Cold/Warm Standby are exposed to both on-demand provisioning failure and sustained SKU shortages — mitigated by Capacity Reservations or Hot Standby Service Fault (Region) ✅ Standby region provides an alternative deployment for regional service failures Service Regional Unavailability ⚠️ Secondary region must be verified for full service parity at design time — absent services block failover regardless of compute readiness Known uses Business-critical workloads with defined RTO/RPO targets that cannot accept region-level risk but do not require continuous multi-region availability; workloads with single-writer data models where multi-region write-conflict resolution is unacceptable; regulatory environments where a designated recovery region must be pre-approved.

Parallel workload distribution (simultaneous active deployment) Pattern Name: Parallel Workload Distribution (Simultaneous Active Deployment) Also Known As: Active-Active Classification: Regional workload distribution, Application Design Scope: Workload — an application-level design pattern; requires the application and its data layer to be explicitly designed for concurrent multi-region operation, Workload (Application) Portfolio Intent: Deploy the same workload simultaneously to two or more Azure regions, all serving production traffic. Context: Two independent drivers lead to this pattern, often simultaneously: the workload serves geographically distributed users who require regional proximity to meet latency targets, and the availability tier demands zero-downtime through region-level failures. A single deployment point cannot satisfy both. Manual failover timelines, standby region promotion, and RPO windows are incompatible with the required availability tier. This pattern is the mandated baseline for Mission-Critical workloads in the Azure Well-Architected Framework. Problem: Passive standby and failover mechanisms introduce recovery time and data loss windows that are incompatible with high-availability targets (e.g. 99.99%+). Meeting both demands requires all regions to be equal active participants — not a primary and a standby. But this demands that the data layer either supports concurrent writes across regions, relies on continuous cross-region replication with a defined consistency model, or is predominantly read-heavy — and that pre-provisioned capacity is maintained in every active region at all times. Forces: Regional failure must produce zero downtime — manual failover timelines cannot satisfy the availability target. Traffic originates from geographically distributed users who require regional proximity to meet latency SLAs. Availability targets (e.g. 99.99%+) eliminate passive standby as a viable option. The application can tolerate eventual consistency or is read-heavy enough that multi-region write complexity is manageable. Once multi-region data access is solved, every region's compute actively serves production traffic — the capacity that Failover Hot Standby holds idle is fully utilised; the cost multiplier buys active production capacity, not idle insurance. Solution Deploy the workload identically to two or more Azure regions. Route production traffic to all active deployments simultaneously via a global load balancer — under normal conditions, each user is directed to the nearest active region, minimising latency. On regional failure, the load balancer automatically rebalances traffic to the remaining healthy regions — no manual promotion, no scale-up delay. All regions are equal peers; there is no concept of primary and secondary. Implementation: Deployment Stamps are commonly used to implement Parallel at scale — multiple active regional instances behind global routing. See Deployment Stamps pattern — Azure Architecture Center. Stamps are not exclusive to Parallel: the same approach can also support Segmented and, in some designs, Failover. Regions active: 2+ (all serving production traffic simultaneously). Typical cost multiplier: ~2–3×. Microsoft guidance — Mission-Critical workloads: The Azure Well-Architected Framework’s Mission-Critical design methodology explicitly advises active-active multi-region deployment as the baseline for workloads targeting 99.99% availability or higher. The application design guidance states: “The application must be able to withstand regional and zone failures. It must be deployed in an active/active model so that the load is distributed among all regions.” The regions and availability zones guide reinforces this: “Mission-critical workloads should use both multiple availability zones and multiple regions.” The WAF Reliability pillar describes active-active as the mechanism to achieve zero downtime, noting it is “ideal for mission-critical workloads that require uninterrupted availability.” Consequences Benefits: Regional failure triggers automatic traffic rebalancing — no manual failover, no service interruption. Lowest RTO of all patterns; zero-downtime regional failure recovery. On regional failure, remaining regions absorb redirected traffic immediately — if at capacity, the workload degrades under load rather than failing completely; degraded performance is a fundamentally better failure mode than an unavailability window. Serves geographically distributed users within latency bounds simultaneously from the nearest active region. Compute deployed per region actively generates production value under normal conditions — the nominal cost multiplier buys utilised capacity, not idle standby insurance. Liabilities: Highest nominal cost (~2–3×) — though compared to Failover Hot Standby (~2×), the effective cost of resiliency is lower: every unit of deployed capacity actively serves production traffic rather than sitting idle as insurance. Requires the application to support multi-region writes or be predominantly read-heavy; write-conflict resolution is an application responsibility. Multi-region CI/CD, distributed observability, and write-conflict handling add steady-state operational overhead — but eliminate the failure-event burden: no failover procedure, no drill schedule, no risk of untested recovery paths inflating actual RTO. Risk posture: Risk Assessment Region Fault ✅ Primary driver; automatic traffic rebalancing handles both partial regional degradation and full regional loss — no promotion or manual steps required Service Fault (Global) ⚠️ No regional workload distribution pattern mitigates a truly global service disruption — but the impact is often partial: only specific SKUs, tiers, or versions of a service may be affected, leaving workloads on unaffected variants operational. Where the risk is intolerable, the mitigation is service substitution: switching to an alternative Azure service with equivalent functionality, or a third-party / self-hosted equivalent Service Fault (Region) ✅ Automatic rebalancing redirects traffic away from the affected region without manual failover Regional Service Capacity Constraint ✅ All regions are pre-deployed and running; no on-demand capacity provisioning required at failover time — if a region fails and remaining regions reach capacity limits, the result is degraded performance under load, not complete unavailability Known uses Mission-Critical workloads targeting 99.99%+ availability per WAF guidance; globally distributed consumer applications where regional proximity is a primary SLA requirement; financial trading and payment platforms where any recovery window is commercially unacceptable; real-time communication and streaming services where failover lag degrades the user experience.

Segmented workload distribution (regional distribution by boundary) Pattern Name: Segmented Workload Distribution Also Known As: Deployment Boundaries, Regional Portfolio Allocation Classification: Regional workload distribution (portfolio scope) Scope: Portfolio / Organisation — a structural pattern for distributing a portfolio of workloads, tenants, or business units across regions; individual workloads within a segment may independently apply any other pattern Intent: Assign each Azure region a distinct, non-overlapping responsibility boundary so that regions are differentiated by ownership and isolation rather than by redundancy. Context: A portfolio of workloads, a multi-tenant application, or a multi-LOB organisation must distribute services or data across regions. The drivers include regulatory boundaries, tenant isolation, blast-radius containment, or operational independence — not simply increasing redundancy. Individual boundaries within the portfolio have materially different criticality tiers, release cadences, and recovery requirements. Problem: Running a second Azure region purely as a Failover standby generates ongoing cost without delivering business value under normal conditions. How can an organisation operate multiple regions so that every region carries real production workload, the cost is justified by utilisation rather than insurance alone, and each region's scope is independent enough that faults and changes in one area do not propagate to others? Forces: Regulatory, sovereignty, or compliance obligations drive geographic boundary placement — but strict data residency that prohibits cross-boundary replication also prevents the cross-region recovery that makes Segmented cost-efficient; a boundary whose data cannot leave its region can only recover within that region (Single Region posture), regardless of what neighbouring segments deploy. Independent release cadences, lifecycle autonomy, and scaling requirements across services, tenants, or business units conflict with coupled shared-infrastructure deployments. Blast-radius containment requirements prevent a single fault or bad deployment from affecting the entire portfolio. This pattern does not answer how each boundary recovers; that choice is made independently per boundary using Single, Failover, or Parallel. Solution Define non-overlapping responsibility boundaries and assign each boundary to a region. Each region owns its boundary exclusively — no region is a replica of another. Each boundary independently selects its own recovery posture (Single, Failover, or Parallel) based on its own criticality and requirements. The key structural advantage is region reuse: because multiple regions are already deployed and carrying real production load, each region can simultaneously serve as the Failover standby or Parallel peer for a neighbouring boundary — the same infrastructure investment delivers both production utilisation and recovery capability. This dual-purpose reuse is only available where cross-boundary data replication is permitted; where strict data residency prohibits it, each boundary must treat itself as isolated and plan recovery within its own region. Implementation: The boundary can be defined at different scopes: Within one application: tenants, markets, release rings, or data partitions assigned to different regions. Across a service portfolio: different applications, domains, or business capabilities intentionally placed in different regions. Segmentation axis Example Geography / data residency EU services and data in West Europe, US services and data in East US Business unit / LOB Finance portfolio in Region A, HR portfolio in Region B Customer tier Premium customer workloads in dedicated region(s), standard in shared region(s) Release ring Ring 0 workloads in Region A, Ring 1 workloads in Region B Scale tier High-volume service groups in larger regions, low-volume groups in smaller regions Segmented is orthogonal to the Single / Failover / Parallel dimension. It answers what is each region responsible for, not how does each responsibility recover? A global organisation might run some boundaries as Single, some as Failover (warm standby), and selected mission-critical boundaries as Parallel — all within one Segmented topology. Consequences Benefits: A fault in one boundary is contained to that region and does not propagate to adjacent boundaries. Each boundary independently selects its own recovery posture, cost level, and compliance configuration. Supports independent release cadences, scaling policies, and lifecycle management per boundary. Region reuse: already-deployed regions carrying production load can simultaneously serve as Failover standby or Parallel peer for neighbouring boundaries — the infrastructure investment delivers both production utilisation and recovery capability without paying for idle standby capacity. Liabilities: Cross-boundary dependencies — shared identity, shared data stores — undermine isolation guarantees and must be minimised by design. Governance overhead scales with the number of active boundaries; requires a formal boundary ownership model to remain manageable. Risk posture: Risk Assessment Service Fault (Region) ⚠️ Fault is contained to the affected boundary; adjacent boundaries continue operating — within-boundary recovery depends on that boundary’s posture Region Fault ⚠️ Only the boundary hosted in the affected region is impacted — RTO/RPO is determined by that boundary's individual recovery posture Regional Service Capacity Constraint ⚠️ Only the boundary in the capacity-constrained region is affected; other boundaries continue operating — mitigation depends on the boundary's own topology (Failover or Parallel provides alternatives; Single does not) Geopolitical Risk ✅ Boundaries can be relocated independently; the rest of the estate continues operating while the affected boundary is relocated Service Regional Unavailability ✅ Each boundary can be independently placed in a region where all required services are available Known uses Geo-distributed enterprise application portfolios; organisations with a federated business model where autonomous business units operate independently with their own release cadence, cost accountability, and compliance obligations; SaaS platforms with tenant-per-region isolation; regulated financial and healthcare services with strict data residency by jurisdiction. See Azure Services - Sample Multi-Region Capabilities Pattern Mapping. 5. Portable workload distribution (full abstraction) Name: Portable Workload Distribution (Full Abstraction) Also Known As: Region-Agnostic Deployment, Cloud-Neutral Deployment Classification: Operational property (applicable to any structural pattern) Scope: Workload — a design property of an individual workload; composable with any structural pattern at either workload or portfolio scope Intent: Fully abstract the workload from the underlying Azure environment so it can be relocated to any Azure region at any time without modifying application code or configuration. Context: A workload is subject to compliance obligations — regulatory, geopolitical, or sustainability — that may require region relocation on short notice. Or the workload's operational requirements include the ability to optimise cost, respond to capacity constraints, or avoid service unavailability across regions. Portability is not the default outcome — it requires an explicit design decision and sustained engineering investment. Without that intent, the default is a workload that is structurally bound to its current region. Problem: Without a portability investment at design time, a relocation trigger forces significant rearchitecting under pressure rather than as a controlled migration. Forces: Compliance obligations — regulatory, geopolitical, or sustainability — may require relocation on short notice; deferring the portability decision converts a design choice into a forced rearchitecting event at the worst possible time. Data portability is the hardest dimension: scheduled backup/restore, continuous replication, and live migration each introduce cost, complexity, and consistency trade-offs that must be accepted at design time. Relocation may be temporary or permanent; the architecture must support both without distinguishing between them at deploy time. A port may be partial (subset of workloads) or full (entire estate); partial porting creates transient cross-region dependencies that must be explicitly designed for and eliminated as the migration progresses. Solution Select and implement a data portability mechanism — continuous replication, backup/restore, or live migration — whose cost, RPO, and operational model are explicitly accepted at design time. The target region is not fixed at design time — it is chosen when a trigger event occurs, and can be any eligible region. The workload stays in its current region under normal conditions and relocates only when a trigger event warrants it. Implementation: Portable is a layered property, not a separate structural topology. The underlying structural topology (Single, Failover, Parallel, or Segmented) determines traffic routing and redundancy; Portable governs whether that topology can be instantiated in a different region without application changes. The cost multiplier adds toolchain and abstraction overhead on top of the chosen structural topology. Data portability — the critical path: Compute portability is straightforward — container images and environment-agnostic configuration are standard practice. Data portability is the harder problem. Two mechanisms make it achievable: Continuous replication: The data layer replicates to the target region at all times, so the data is already present when a relocation is triggered. Azure Cosmos DB with multi-region writes, Azure SQL Database geo-replication, and Azure Storage geo-redundancy (RA-GRS/RA-GZRS) are common implementations. Continuous replication minimises RPO but adds steady-state cost. Automated data migration: A codified and continuously tested migration pipeline moves data to the target region at relocation time. Appropriate when continuous replication cost is not justified, or when the data tier does not support native geo-replication. The migration must be automatable, testable in isolation, and fast enough to satisfy the workload’s RTO for the trigger event. Port modes: Partial vs. Full A port — the act of relocating a workload using the Portable pattern — can be scoped in two ways: Partial port: A subset of workloads is relocated to the target region while others remain in the source region. This creates transient cross-region dependencies — service calls, data access, shared identity — between moved and not-yet-moved workloads. These dependencies must be explicitly designed for, monitored for latency and failure, and eliminated progressively as the migration advances. Partial porting is the natural execution mode for large estates where simultaneous full relocation is operationally infeasible. Full port: All workloads are relocated to the target region, either simultaneously or in a planned sequence that keeps cross-region dependencies only for the duration of each step. A full port is a long-term, intentional change of primary region. It is fundamentally different from a Failover event: Dimension Failover Full Port (Portable) Intent Quick recovery and return to primary region when resolved Permanent change of the region Duration Temporary — primary is restored after the event Long-term or permanent — target becomes the new primary Return Expected — traffic and workloads revert to original region Not expected — no return is planned Driver Region fault, outage, or transient unavailability Compliance, cost, sustainability, or strategic decision Transition Time Aiming for RTO Transition can take weeks or months (but it can be designed to serve the Failover purpose and meet RTO and RPO requirements) Transition disruption Minimal — automated or semi-automated failover Managed — gradual migration with a cross-region dependency period The Portable pattern must support both modes and both scopes. A workload that can only be relocated as an atomic all-or-nothing operation has limited practical utility; a workload designed for incremental partial porting is far more executable at scale. Consequences Benefits: Workload can relocate to any Azure region without application changes — eliminates region lock-in. Target region is determined at the time of the trigger, not at design time — unlike Failover's fixed designated standby, the destination can be any eligible region and can change between port events as requirements evolve. Primary architectural mitigation for compliance-driven relocation risks (Geopolitical Risk, Sustainability Constraint). Relocation can be temporary (workload returns after trigger resolves) or permanent — the architecture supports both without distinguishing between them. Liabilities: Portability is costly to establish and maintain; data portability and the abstraction layer add ongoing engineering and toolchain overhead. Data portability is the hardest and most underestimated engineering challenge — relocating compute is straightforward; relocating live data at acceptable cost, latency, and consistency is not. Introduces dependency on the abstraction toolchain — portability conventions must be actively enforced as engineering standards; without governance, individual implementation decisions erode them over time. Risk posture: Risk Assessment Geopolitical Risk ✅ Primary driver — region-agnostic workload relocates to a compliant region; unportable workloads face forced migration under time pressure Sustainability Constraint ✅ Workload moves to a region with the required sustainability profile without application-level changes Regional Service Capacity Constraint ✅ Workload can be relocated to an alternative region with available capacity — addresses both on-demand provisioning failure and sustained shortages Region Fault ✅ Workload can be relocated to an alternative region; recovery speed depends on data portability readiness Service Regional Unavailability ✅ Workload can be redirected to any region where required services are available — portability removes the fixed-region constraint Known uses Workloads subject to data sovereignty or geopolitical obligations that may require region relocation on regulatory notice; sustainability-committed workloads that may need to move to regions with a lower carbon intensity; workloads in rapidly expanding organisations that need to follow business growth into new geographies without rearchitecting. Several patterns are adapted from Gregor Hohpe's cloud strategy patterns: Multi Cloud Architecture: Decisions and Options — Architect Elevator. See Azure Services - Sample Multi-Region Capabilities Pattern Mapping. Related patterns Portable vs. Failover — Both result in a workload running in a different region, and a full port and a Hot Standby activation look nearly identical at execution time. The distinctions are fundamental: Failover is a topology (one region is permanently designated as standby); Portable is a property that can be layered on top of any topology. Failover requires a fixed secondary region to be designated at design time — the target is known, pre-provisioned, and not interchangeable. Portable has no fixed target: the destination region is chosen at the time of the trigger, can be any eligible region, and can differ between port events as compliance, cost, or operational requirements change. Failover is triggered by an unplanned disruption and is temporary — the expectation is to return to the original primary when the event resolves. A Portable port is triggered by a deliberate decision and is permanent — the destination becomes the new primary with no planned return. A Failover workload can also be Portable, applying both patterns simultaneously: Failover handles unplanned disruptions; Portable handles deliberate relocation decisions. They are orthogonal — not alternatives. Azure service pattern mapping - sample services Each pattern places specific demands on the services that compose the workload. Some services provide native capabilities — zone redundancy, built-in replication, independent deployment per region, parameterised failover targets — that simplify implementation of specific patterns. Others provide fewer native capabilities, requiring the pattern to be constructed at the deployment and application level. The service examples below illustrate how native capabilities map to pattern implementation for four representative services across IaaS and PaaS. Azure Virtual Machines Azure VMs are IaaS compute — the platform provides the virtualisation layer and the building blocks (Availability Zones, proximity placement, VM scale sets) but leaves resilience orchestration to the operator. This makes VMs fully flexible: every pattern is implementable, but none is provided out of the box — the operator constructs the desired topology. Attribute Value Cross-Region Replication Azure Site Recovery (ASR) — continuous replication to any target region; orchestrated failover supported Deployment model Independent — each VM or scale set is deployed per region with no shared control plane; fully independent instances per region are the norm Provisioning guarantee Capacity Reservations: pre-purchase VM SKU and quantity in any region; eliminates capacity risk at failover or scale-up Pattern implications Single: One region plus Availability Zone redundancy is the default deployment model; AIRM can audit zone distribution across VM resources. Failover: ASR makes Cold, Warm, or Hot standby feasible depending on how much compute is pre-provisioned. Parallel: Independent VM deployments per region behind a global load balancer are feasible; write-conflict handling remains an application responsibility. Segmented: VMs can be partitioned by boundary, region, or workload ownership with independent recovery postures. Portable: VMs are redeployed to the target region using ASR (continuous replication already in place) or fresh IaC deployment with capacity reservations pre-secured; the original region's instances are decommissioned once the target is operational. Azure App Service Azure App Service is a fully managed PaaS application platform. An App Service Plan runs in a single region and provides zone redundancy within that region, but no built-in replication or failover beyond it. Any topology beyond Single Region is constructed at the deployment level using independent plans and external traffic routing. Attribute Value Cross-Region Replication No live replication — the platform does not continuously replicate app content or state between regions; cross-region failover is constructed via independent plans and global traffic routing. Custom backup/restore (Basic tier and above) provides scheduled backup of app files and configuration to a storage account, restorable to any region — this supports Cold Standby and Portable scenarios. Deployment model Independent — each App Service Plan is a standalone regional resource; no shared control plane between plans in different regions Provisioning guarantee Not supported — no mechanism to pre-reserve compute in a target region; a Hot Standby (always-running plan) is the only way to guarantee capacity availability Pattern implications Single: A single App Service Plan in one region with zone redundancy is the normal starting point. Failover: Use independent App Service Plans per region with Front Door or Traffic Manager; the application state must live elsewhere. Parallel: Independent plans per region fit active-active traffic routing, but the data tier must support the write/read pattern. Segmented: Separate plans per boundary or tenant group provide clean ownership and isolation. Portable: A new App Service Plan is deployed in the target region and traffic is routed to it; the original plan is decommissioned once the target is serving production. Connected stateful services (databases, storage) must be independently relocated or already replicated to the target. Azure SQL Database (Business Critical) Azure SQL Database Business Critical is a fully managed relational database with extensive built-in resilience at every level: local high availability within a region (Always On replicas), zone redundancy, and native replication to other regions (active geo-replication, auto-failover groups). This breadth of built-in capability means more patterns are natively supported without additional construction. Attribute Value Cross-Region Replication Active geo-replication: continuously synchronised readable secondary in any region (up to 4 secondaries); auto-failover groups: stable read-write and read-only listener endpoints that survive failover without connection string changes Deployment model Managed instance per region — each database or elastic pool is a regional resource; geo-replication creates linked but independently addressable secondaries Provisioning guarantee No explicit provisioning at current tier — the platform manages the underlying infrastructure. Scaling up or changing service tier is subject to regional capacity availability and subscription quota, as with any Azure service. Geo-replicated secondaries are pre-provisioned and running before any failover, so failover itself does not require on-demand capacity provisioning Pattern implications Single: A single database in one region with zone-redundant replicas provides high availability without additional topology. Failover: Geo-replication and auto-failover groups are the built-in path; the service is natively designed for this pattern. Parallel: Readable secondaries can serve read traffic, but fully symmetric writes across regions are not natively supported. Segmented: Each boundary can own its own database instance and replication policy. Portable: A geo-replica is added on demand in the target region; once seeded, it is promoted to primary via planned failover (no data loss); the original region's replica is then removed. This is natively supported as a database relocation scenario. Azure API Management Azure API Management (APIM) is a fully managed API gateway platform. Within a single region it provides zone redundancy for the gateway. Beyond that, APIM offers a native multi-region deployment capability (Premium tier) that places gateway nodes into additional regions while sharing a single management plane. This makes it representative of services with a shared-control-plane architecture where the data plane scales independently per region. Attribute Value Cross-Region Replication Configuration replicated automatically to all regional gateway units; no stateful data plane — backend data replication is the responsibility of connected services Deployment model Shared control plane — a single APIM instance owns the management plane; additional regional gateway units are extensions of the same instance, not independent deployments Provisioning guarantee Not supported — capacity is allocated per gateway unit (scale units); provisioning additional units in a region before a failover event is the closest equivalent to a reservation Pattern implications Single: One APIM instance in one region with zone-redundant gateway units is viable for region-bound APIs. Failover: Secondary APIM capacity or a second instance can be provisioned, but the management plane must stay consistent. Parallel: The multi-region add-on is a strong native fit; gateway units run in multiple regions behind global routing with shared configuration. Segmented: Separate APIM instances per boundary, or boundary-specific gateway units where shared management-plane control is acceptable. Portable: Gateway units are added on demand in the target region while the original continues serving traffic; once the target is operational, the original region's gateway units are removed — completing the relocation without recreating the instance. Note: the APIM control plane (instance state) remains in the original region where the instance was created; unless a fault renders that region wholly inoperable, this is not an implication for the pattern — the control plane does not carry data-plane cost and does not affect request routing once gateway units are active in the target region. From patterns to a cloud growth strategy The patterns in this article show that regional distribution is not a single decision — it is a spectrum of options, each with a different cost, complexity, and risk mitigation profile. The patterns are not mutually exclusive: a portfolio — or even a single workload — may combine multiple patterns to achieve its reliability, compliance, and operational goals. Having the full range of patterns available does not answer the harder question: which patterns are right for your organisation, which applications need them, and what will it take to get there? That is a strategy question — and it requires a deliberate answer. Most organisations today operate their workloads in the Single Region or Failover pattern. Transitioning from that baseline to Parallel, Segmented, or Portable distribution is not an infrastructure change — it is a programme of work that requires investment justification, architectural readiness, and a governed execution plan. A Cloud Growth Strategy based on regional workload distribution starts by defining the organisation's objectives: what reliability targets must be met, which compliance or sovereignty constraints apply, what operational scale is planned, and where the current estate falls short. From those objectives it derives what the regional footprint should look like for this organisation — not as a generic best practice, but as a concrete commitment about which patterns apply to which parts of the portfolio, at what pace, and at what cost. Conclusion Azure's global footprint makes regional workload distribution a choice for every workload — but not a requirement for all of them. The decision starts with risk: the Risk Catalog identifies which fault types and capacity or compliance constraints are actually relevant to the workload, and what blast radius each carries. From that foundation, five patterns emerge — Single Region, Failover, Parallel, Segmented, and Portable — each resolving a distinct set of forces at a different cost and complexity point. Real Azure services rarely fit one pattern cleanly; the service examples in this article illustrate how capability gaps, consistency models, and replication architectures constrain which patterns are structurally achievable. Translating this into organisational practice requires a deliberate Cloud Growth Strategy: classify applications by criticality, assess their suitability for each pattern against their current state, and produce a governed distribution map that is maintained as the portfolio and platform evolve.

Thank you in advance for your advice and insights!Turning Azure Policy Signals into Actionable Governance Insights
Most Azure Policy reporting stops at compliance status. Useful, yes — but not enough. When a control fails, teams need to know what failed, why it matters, and who should act. That gap becomes obvious at enterprise scale. A failed policy evaluation is only a signal. By itself, it does not tell you whether the issue affects recovery, auditability, telemetry, or another control leaders care about. That is why joining PolicyStates with PolicyAssignments matters. One tells you the outcome. The other tells you which control was applied, where, and in what governance context. Together, they turn Azure Policy from a compliance feed into a control intelligence layer. The problem: PolicyStates alone tells you what is non-compliant, but not always why it matters Microsoft’s sample ARG queries quickly show which resources are non-compliant. Helpful, but still incomplete. They show the result, not the business meaning. At enterprise scale, that distinction matters. A storage account without blob soft delete is a recovery risk. Missing Azure Activity logs creates an audit gap. A virtual machine without Azure Monitor Agent creates a telemetry blind spot. Azure Policy shows the state. The join to PolicyAssignments explains why it matters. There is also a technical reason to care about assignments. The same PolicyDefinitionId can appear in multiple assignments across different scopes. That makes PolicyAssignmentId the operational key. How Azure Policy compliance data flows Azure Policy evaluates resources against JSON-based rules. Those rules are packaged as policy definitions and can be grouped into initiatives. Once assigned to a scope, the policy engine evaluates matching resources during creation, updates, assignment changes, and regular compliance cycles. The results are exposed through PolicyStates and PolicyEvents, and can also be queried through Azure Resource Graph. This is the architecture flow for turning the ARG query into a scheduled governance report through Logic App: The key shift is operational. A Logic App can run the ARG query on a schedule, format the results, and email them to stakeholders. That turns a manual check into a repeatable governance report. The analytical pattern: enrich compliance with assignment context The analytical flow is straightforward: Configure a Recurrence trigger in Logic App so the report runs on the schedule you need. Use an HTTP action with managed identity to run the ARG query against PolicyStates and join it to PolicyAssignments. Filter on the control assignments that matter to your organisation and shape the response into a compact HTML table or CSV. Send the output by email to governance, engineering, or audit stakeholders so the insight reaches people without requiring them to open the portal. In practice, the query starts with non-compliant resources and enriches them with assignment details such as the assignment name and optional metadata like owner. That is the shift from raw signal to governance insight. A simple implementation pattern is: schedule the Logic App, run the ARG query with managed identity, format the output, and send the report. HTML works well for leadership emails; CSV is better for downstream analysis. ARM template for the Logic App If you want to deploy this pattern instead of building it step by step, I have also published an ARM template for the Logic App in my GitHub repository. The template is intended to help you stand up the scheduled policy compliance workflow faster and then customise the query, email recipients, and formatting for your own environment. This makes the architecture in this post directly reusable: schedule the Logic App, run the ARG query, shape the output, and send a control-focused report without having to assemble the workflow from scratch. See the repository for the template and related Microsoft Sentinel automation content. Reference ARG query policyResources | where type =~ 'microsoft.policyinsights/policystates' | where properties.complianceState == 'NonCompliant' | extend ResourceId = tostring(properties.resourceId), PolicyAssignmentId = tolower(trim(@" ", tostring(properties.policyAssignmentId))), SubscriptionId = tostring(subscriptionId), LastEvaluated = todatetime(properties.timestamp) | extend ResourceName = tostring(extract(@"[^/]+$", 0, ResourceId)) | extend ResourceProvider = tostring(extract(@"providers/([^/]+)/", 1, ResourceId)) | extend ResourceCategory = case( ResourceId has "Microsoft.Compute/virtualMachines", "VM", ResourceId has "Microsoft.Storage/storageAccounts", "Storage", ResourceId has "Microsoft.Network/virtualNetworks", "Network", ResourceId has "Microsoft.Sql/servers", "SQL", ResourceId has "Microsoft.KeyVault/vaults", "Key Vault", ResourceProvider =~ "Microsoft.Compute", "Compute", ResourceProvider =~ "Microsoft.Storage", "Storage", ResourceProvider =~ "Microsoft.Network", "Network", ResourceProvider =~ "Microsoft.KeyVault", "Key Vault", "Other" ) | project ResourceId, ResourceName, ResourceCategory, SubscriptionId, PolicyAssignmentId, LastEvaluated | join kind=inner ( policyResources | where type =~ 'microsoft.authorization/policyassignments' | extend AssignmentName = tostring(properties.displayName), AssignmentId = tolower(trim(@" ", tostring(id))), Scope = tostring(properties.scope), PolicyOwner = tostring(properties.metadata.owner) | where AssignmentName has "CSTM--Configure blob soft delete on a storage account" or AssignmentName has "Configure Azure Activity logs to stream to specified Log Analytics workspace" or AssignmentName has "Audit diagnostic setting for selected resource types" | project AssignmentId, AssignmentName, Scope, PolicyOwner ) on $left.PolicyAssignmentId == $right.AssignmentId | project SubscriptionId, ResourceId, ResourceName, ResourceCategory, AssignmentName, AssignmentId, Scope, ['LastEvaluated[UTC]'] = LastEvaluated What this query is doing — in plain English This query finds Azure resources that are currently NonCompliant with Azure Policies by reading data from the PolicyStates table in Azure Resource Graph. It extracts useful details such as Resource ID, Resource Name, Resource Type/Category, Subscription ID, Policy Assignment ID, and the last evaluation timestamp. Resources are categorized into groups like VM, Storage, Network, SQL, and Key Vault based on their resource type/provider. It then joins the non-compliant resources with specific policy assignments (three named policies) to show which policy caused the non-compliance, along with the policy scope, and evaluation time. Why CISOs and governance leaders should care For a CISO, this is not about counting failed evaluations. It is about knowing whether critical controls are drifting, where the risk sits, and who owns the response. Three use cases stand out: Audit readiness: show control-focused evidence instead of a flat list of resource IDs. Ownership: enrich assignments with metadata so findings can be routed to the right team faster. Prioritization: focus on the controls that matter now, not every non-compliant resource in the estate. Operational benefits: scalable, repeatable, and security-friendly From an engineering perspective, this pattern is attractive because it is repeatable, scalable, and aligned to the native Azure Policy data model. It also fits naturally into operational tooling. The enriched output can feed workbooks, dashboards, Sentinel content, and alerting workflows. Closing thought At small scale, Azure Policy can be reviewed in the portal. At enterprise scale, that quickly becomes noise. The better question is not Which resources are non-compliant? It is Which important controls are failing, where, and who should act? That is what makes this pattern powerful: it turns Azure Policy from a compliance dashboard into a control intelligence layer that works for both engineers and executives.Securing data and access in the era of AI with Microsoft Entra and Microsoft Purview
