Azure Course Blueprints
Each Blueprint serves as a 1:1 visual representation of the official Microsoft instructor‑led course (ILT), ensuring full alignment with the learning path. This helps learners: see exactly how topics fit into the broader Azure landscape, map concepts interactively as they progress, and understand the “why” behind each module, not just the “what.” Formats Available: PDF · Visio · Excel · Video Every icon is clickable and links directly to the related Learn module. Layers and Cross‑Course Comparisons For expert‑level certifications like SC‑100 and AZ‑305, the Visio Template+ includes additional layers for each associate-level course. This allows trainers and students to compare certification paths at a glance: 🔐 Security Path SC‑100 side‑by‑side with SC‑200, SC‑300, SC‑500 🏗️ Infrastructure; Ai & Dev Path AZ‑305 alongside Ai-103, AZ‑104, Ai‑200, AZ‑700, AZ‑140 This helps learners clearly identify: prerequisites, skill gaps, overlapping modules, progression paths toward expert roles. Because associate certifications (e.g., SC‑300 → SC‑100 or AZ‑104 → AZ‑305) are often prerequisites or recommended foundations, this comparison layer makes it easy to understand what additional knowledge is required as learners advance. Benefits for Students 🎯 Defined Goals Learners clearly see the skills and services they are expected to master. 🔍 Focused Learning By spotlighting what truly matters, the Blueprint keeps learners oriented toward core learning objectives. 📈 Progress Tracking Students can easily identify what they’ve already mastered and where more study is needed. 📊 Slide Deck Topic Lists (Excel) A downloadable .xlsx file provides: a topic list for every module, links to Microsoft Learn, prerequisite dependencies. This file helps students build their own study plan while keeping all links organized.

Cloud Native Platforms: Run
Audience: SREs (Site Reliability Engineers), platform engineers, engineering managers running production systems Reading time: 8 minutes Series: Cloud Native Platforms. Build, Run, Evolve. This is Part 2 of 3. Most systems are designed thoughtfully. Most operations are inherited reactively. The systems that survive are not the ones built with the most care. They are the ones operated with the most discipline. Production has a way of revealing every shortcut taken during design and every assumption left unverified. This post is about what it takes to operate a platform once the build is done. How they are run, not how they are built Systems are not defined by how they are built. They are defined by how they are run. A well-designed system that is operated reactively will fail in production. A modestly designed system that is operated with discipline will outperform it. Five operational disciplines decide which side of that line a platform lives on. Each one is engineering work, not a checklist for someone else to handle. Figure 1. The incident lifecycle as a state machine. The states are not optional steps. They are the contract between the team and the system. 1. Observability is the backbone of reliability Without observability, every operation becomes a guess. As systems grow, the cost of guessing rises faster than the cost of seeing. Part 1 of this series argued that observability is a design property: instrumentation contracts, request id propagation, structured logging schemas. Production is where those design choices either pay off or do not. Strong observability in production is a contract that lets any engineer answer three questions in minutes: what failed, why it failed, and what the impact was. The shape of that contract matters more than the tool that implements it. (This three-question framing is community-popularised through the SRE community and writers such as Charity Majors. See Honeycomb's What is Observability for the canonical articulation of the three-pillars and question framing; the substance is older than the framing.) Dashboards organised around user journeys, not infrastructure components Service level indicators (SLIs: the specific measurements you care about, e.g., success rate, p99 latency) chosen from the user's perspective, not the database's Alerts that page only on burn-rate against an SLO (Service Level Objective: the target value of an SLI, e.g., 99.9% of requests complete in under 800ms over a rolling month) using a multi-window strategy. A short window catches fast burns; a long window catches slow drifts. This is what makes SLOs operational rather than decorative. Sampling and retention tuned for cost, but never for blind spots The distinction between MTTA (mean time to acknowledge: how fast someone notices) and MTTR (mean time to restore: how fast service returns) tracked separately. Conflating them hides whether the team's bottleneck is detection, response, or fix. In practice The pattern that works: rebuild the operational view around two or three user journeys (sign-in, place order, view history) rather than per-component charts. Tie alerts to error budget burn rather than raw threshold crossings. Track MTTA and MTTR separately so the team's actual bottleneck (detection, response, or fix) is visible. The investment is rethinking what to measure, not buying a new tool. The return is that incidents stop being discovered by customer complaints first. Teams that make this shift typically find their existing telemetry was sufficient; only the questions being asked of it were wrong. If a dashboard cannot answer "what is the user experiencing right now", it is not an observability dashboard. It is decoration. 2. Alerts are signals, not notifications More alerts do not mean better monitoring. In practice, the opposite is true. Once alerts outpace the team's ability to act, important signals start getting missed. Effective alerting works to a small set of rules: Severity that maps to action, not to technical category Ownership baked in, never inferred at runtime Thresholds tied to user impact, not raw metric values Noise treated as a defect, with a regular review cadence Suppression and grouping for known multi-alert patterns In practice The pattern that works: audit every alert against one test, "what action would I take in the next five minutes if this fires now?" Demote alerts with no answer to dashboards. Remove alerts where the answer is the same as another alert's. Group related alerts so one incident produces one page, not twelve. Most teams discover their alert volume drops by an order of magnitude after a thorough audit, and the alerts that remain start getting trusted again. Trust is the precondition for every other operational practice. Without it, on-call rotations decay into noise filtering and the real signals get missed. Figure 2. From raw events to pages, in approximate orders of magnitude. The numbers vary by team and workload; what does not vary is that each stage needs to remove one to two orders of magnitude of noise. Teams that page on raw events end up with on-call rotations nobody trusts. 3. Incident response is a practiced muscle Failures are inevitable. Unstructured response is not. The teams that recover quickly do not improvise during incidents. They follow a structure that has been practiced when nothing was on fire. The structure is intentionally simple, because incident time is the worst time to negotiate roles. Clear roles: incident lead, communications lead, scribe, subject matter expert (the RACI model, Responsible-Accountable-Consulted-Informed, adapted for incident response) Defined escalation paths with clear handoff criteria. Escalation means re-paging to a higher tier or specialist, not returning to detection. The lifecycle diagram in Figure 1 makes the distinction explicit. Runbooks for the top failure modes, kept short enough to actually be read Status communication on a fixed cadence, even when there is nothing new to say. Customer comms and internal comms are tracked separately. Blameless postmortems (focus on the system that allowed the failure, not the person who pushed the button) that produce action items the team actually completes Game days: scheduled exercises that simulate failure modes (region outage, dependency unavailability, traffic spike) under controlled conditions, so gaps in runbooks are found before incidents do In practice The pattern that works: name the incident lead and the comms lead before the first message goes out. Write runbooks short enough to be scannable at 3 AM. Run blameless postmortems with action items that actually get tracked to completion. Schedule game days quarterly so the runbooks are exercised before real incidents. Teams that operate with this structure do not have more engineers; they have engineers who are not single points of failure during recovery. The deepest experts stay the deepest experts, but the platform stops depending on whether they happen to be online. Implementation note A short, well-structured runbook outperforms a long, exhaustive one. The goal during an incident is not to think. It is to act on a procedure that has been thought through in calmer times. # Runbook header pattern (keep it scannable in incident time) title: High latency on order API slo_protected: # this runbook protects two SLOs - order-completion-success - order-completion-latency severity: # derived from burn rate, not declared fast_burn: P1 # 14.4x budget burn over 1 hour => page now slow_burn: P2 # 6x budget burn over 6 hours => investigate owner: payments-team indicators: # triggers for evaluation, not severity - p99 (99th-percentile) latency exceeds the SLO target for 5 min - error rate exceeds the SLO target for 3 min on order-completion first_actions: - Open the order-journey dashboard. Confirm impact in business terms. - Check Service Bus queue depth and dead-letter rate (the most common cause of API latency under load is downstream backpressure) - Verify Cosmos DB RU/s saturation and partition hotspots - Inspect the most recent deployment for behavioural changes escalate_if: - Latency does not recover in 15 min - Error rate exceeds 5% (fast burn against the SLO) - Customer reports arrive before our own signals do rollback_path: - Feature flag "new-order-pipeline" can be disabled per-tenant - Last known good deployment id is in the release tracker note_on_scaling: # CPU is rarely the cause of latency in this service. Scale only after # confirming the bottleneck is compute, not a downstream dependency or # queue depth. Adding capacity to a saturated downstream amplifies the # incident; it does not resolve it. The general principle behind that last note travels beyond this runbook: scale-out is the right remediation for compute saturation, not for downstream saturation. When latency rises because a database, queue, or external dependency is saturated, adding capacity in front of the bottleneck moves more requests into the bottleneck and makes the incident worse. This is one of the most common operational mistakes when the dashboard shows red and the on-call instinct says "add more". 4. Release confidence is engineered Releases get harder as systems grow. The platforms that ship confidently at scale have engineered the path, not learned to fear it. The patterns that change the math: Feature flags that allow change without deploy Canary deployments (releasing the new version to a small slice of traffic first, watching error budget burn before continuing) that surface problems on a small slice Gradual rollouts with automated rollback triggers Database migrations split from application releases Release coordination that scales with services, not with team size In practice The pattern that works: every change ships behind a feature flag, canary deployments take a small slice of traffic first, and rollback is a one-click step in the pipeline rather than a procedure to be invented during an incident. The cost is the discipline of building rollback paths and exercising them. The return is releases that stop being events. Issues that previously triggered full rollbacks get isolated to a slice and rolled back automatically before they reach most users. The willingness to ship smaller, more frequent changes follows directly from the confidence that bad changes can be undone fast. Big releases feel safe because they are rare. They are actually risky because every change rides together. 5. Reliability is continuous, not a milestone Reliability is not achieved through tools alone. It requires continuous refinement, feedback-driven improvement, and a budget that the team can spend on operational work without negotiating each time. The disciplines that keep systems reliable over years are codified well in the SRE-book framing of service level objectives and error budgets (the canonical reference is the Google SRE Book chapter on Service Level Objectives, with the operational follow-up in the SRE Workbook chapter on alerting on SLOs). The names matter less than the practice they enable. SLOs chosen from the user's perspective, with two or three per service rather than ten. More SLOs means none of them shape behaviour. Error budgets: the inverse of the SLO, expressing how much unreliability the team is willing to spend in a window. Used up early in the month means slow down on releases. Healthy means feature work keeps moving. Multi-window burn-rate alerting turns SLOs from dashboards into pages: short window catches catastrophic failures, long window catches slow drift. Without burn-rate alerting, SLOs are observation, not operation. (The pattern is documented in the SRE Workbook.) Reliability work has its own backlog, prioritised against features. Not a wishlist after every incident. Regular game days that exercise failure modes (region failover, dependency outage, traffic spike) before they happen for real Capacity planning informed by data, not by anxiety In practice The pattern that works: define two or three SLOs per service, expressed from the user's perspective. Compute the error budget weekly. When the budget is healthy, ship feature work. When the budget is burning fast, slow down and fix the cause. The conversation about which incidents matter and which can wait becomes possible because there is a shared number to point at. Reliability becomes a quantified property of the platform, not an opinion debated at every retrospective. Teams that adopt this discipline stop having the recurring "how reliable do we need to be?" argument and start having data-grounded trade-off discussions instead. A scenario that ties it together A platform was launching a new region. The build had gone well. Day 1 was clean. Two weeks in, latency started creeping up during peak hours. Alerts fired on raw thresholds, but no one could tell which ones to trust. Incident calls turned into long debugging sessions because three different teams owned overlapping pieces of the request path. The team did not start by buying a new tool. They started by treating operations as engineering work. The dashboard was redesigned around the user journey. Alerts were audited and most were demoted or removed. Roles for incident response were written down. A short runbook covered the top failure modes. Releases were broken into canary slices behind feature flags. None of this was new. It was discipline applied consistently to work that was previously assumed to be someone else's. The next region launch took half the effort, and the team's mean time to restore on the failures that did happen was measurably lower. What teams get wrong The common pattern is treating Day 2 as the cost of Day 1. Teams design beautifully, ship fast, then quietly absorb the operational debt. Dashboards proliferate. Alerts grow louder. Postmortems pile up. The fix is not more dashboards. It is treating operations as engineering work with the same rigour as feature delivery. Operability is a property the system either has or does not. It is not earned by adding monitoring. It is earned by designing for visibility and operating with discipline. Where to start The most concrete starter from this post: an alert audit. List every alert that fires in the next week and apply a single test to each one: "what action would I take in the next five minutes?" Demote the alerts that have no answer. Remove the alerts where the answer is the same as another alert's. The audit takes a morning. The result usually halves alert volume and lifts trust on what remains, which is the precondition for every other operational practice in this post. The shift The most important shift in maturity is not technical. It is in stance. The shift is from shipping software to operating systems: Operations is not a phase that follows engineering. It is engineering. Reliability is not a milestone reached. It is a discipline practiced. Incidents are not interruptions to the work. They are the work. The teams that internalise this shift run platforms that are smaller, calmer, and more trusted. They do not have fewer incidents because their systems are more advanced. They have fewer incidents because their operational discipline is more consistent. Part 3 of this series argues that the same discipline applies again, in a different domain: the practices that make platforms operable are the practices that make AI useful in delivery.

From Prompt to Production: Building Azure Architecture Diagrams with AI
Author: Arturo Quiroga, Senior Partner Solutions Architect — Microsoft Cloud architects spend significant time translating ideas into architecture diagrams. They toggle between Visio, draw.io, pricing calculators, and documentation. According to the 2024 Stack Overflow Developer Survey, 61% of developers spend more than 30 minutes a day searching for answers or solutions, time lost to context-switching rather than design. What if you could describe your architecture in plain English and get a diagram, cost estimate, and deployment guide in minutes? The Challenge: Fragmented Architecture Workflows Designing Azure architectures today typically involves multiple disconnected steps: Sketch the architecture in a diagramming tool Look up official Azure icons and drag them into place Research pricing across regions using the Azure Pricing Calculator Validate the design against the Well-Architected Framework (WAF) Write deployment documentation and Infrastructure as Code templates Compare alternative designs manually Each step lives in a different tool, and keeping them in sync as designs evolve is costly. The Azure Architecture Diagram Builder brings these workflows together in a single browser-based experience. How It Works Describe your architecture in natural language, for example "A HIPAA-compliant healthcare platform with FHIR APIs, event-driven processing, and multi-region disaster recovery", and the AI generates a diagram with grouped services, data flow connections, and logical organization. Figure 1. Enter a natural-language prompt describing your architecture. Curated example prompts help you get started, and you can optionally upload an existing diagram for the AI to analyze. The tool uses Azure OpenAI to power generation across multiple models, enabling you to choose the model that best fits your scenario — from fast iterations to deeper reasoning. Key Features AI-Powered Architecture Generation Describe what you need in plain English, and the AI creates an architecture diagram with: 714 official Azure service icons across 29 categories Smart grouping: services are logically organized (Frontend, Backend, Data, Security) Data flow connections: labeled edges showing how data moves through the system 13 curated example prompts: from simple web apps to complex enterprise scenarios like Zero Trust networks, Industrial IoT with 5,000+ sensors, and global multiplayer gaming backends Figure 2. A generated industrial IoT architecture. Top: the clean diagram view as initially produced. Bottom: the same diagram with per-service monthly cost overlays toggled on, plus a running subscription total in the toolbar. Architecture Image Import Already have an architecture on a whiteboard or in a screenshot? Upload the image and let the AI analyze it, mapping services to official Azure icons and recreating the architecture as an editable, interactive diagram. Figure 3. Upload a photo of a whiteboard sketch (top-right reference panel) and the AI recreates it as an editable diagram with official Azure service icons and labeled data flow connections. ARM Template Import Import existing ARM templates to visualize your current infrastructure. The AI parses resource definitions and dependencies, groups related resources into logical layers, and produces a meaningful diagram of what you actually have deployed — a fast way to document an inherited environment or sanity-check a template before deployment. Figure 4. ARM template import in action. Top: the parser status banner while resources and dependencies are being analyzed. Bottom: the resulting diagram, with resources auto-grouped into logical layers (Web Tier, Data Layer, Container Platform, Observability & Logging) and a Generated from: ARM Template badge linking the diagram back to its source file. Well-Architected Framework Validation Validate your architecture against all five WAF pillars — Security, Reliability, Performance Efficiency, Cost Optimization, and Operational Excellence. The validator provides: An overall WAF score with pillar-level breakdowns Specific findings with severity levels Actionable recommendations you can select and apply Select the recommendations you agree with, and the AI regenerates an improved architecture incorporating those changes. Figure 5. WAF validation results showing the overall score, per-pillar breakdowns, and individual findings with severity badges. Tick the recommendations you want and the AI rebuilds the diagram with those changes applied. Multi-Model Comparison Run the same architecture prompt through multiple AI models side-by-side and compare: Architecture Comparison: service counts, connection counts, groups, token usage, and latency Validation Comparison: WAF scores across models, severity breakdowns, and finding counts Apply Winner: pick the best result and apply it to the canvas with one click Present Critique: a talking avatar narrates the AI-generated ranking with live closed captions Figure 6. Multi-model comparison. Top: select the models and reasoning effort, then enter the prompt. Bottom: side-by-side results across all selected models with service counts, latency, token usage, and Fastest / Cheapest / Most Thorough badges. Multi-Region Cost Estimation Get cost estimates from the Azure Retail Prices API across 8 Azure regions: East US 2, Australia East, Canada Central, Brazil South, Mexico Central, West Europe, Sweden Central, and Southeast Asia. Features include: Color-coded cost legend (green / yellow / red thresholds) SKU and tier information for each service Export options: CSV, JSON, plain-text summary, and an analysis report with top cost drivers, Reserved Instance flags, and a ranked multi-region comparison table Figure 7. The cost legend overlay shows per-service pricing with color-coded thresholds. The region selector in the toolbar lets you re-price the entire architecture in any of eight Azure regions. Deployment Guide Generation with Bicep Generate step-by-step deployment documentation including: Prerequisites and Azure resource requirements Step-by-step deployment instructions Bicep templates for each service (Infrastructure as Code) Post-deployment verification steps Security configuration recommendations Figure 8. Each generated Deployment Guide opens with the architecture name, an estimated deployment time, and a prerequisites checklist covering subscription roles, CLI versions, Microsoft Entra ID permissions, and region requirements, followed by numbered, copy-ready deployment steps. Figure 9. The Infrastructure as Code section produces a main.bicep orchestrator plus a per-service module (Log Analytics, Key Vault, Cosmos DB, SQL Database, Event Hubs, Azure Functions, and more). The Download All Templates button packages everything into a ready-to-deploy folder. Workflow Animation & Avatar Presenter Visualize how data flows through your architecture with step-by-step animations that highlight services on the canvas as each step plays. When the Azure Speech Service is configured, a photorealistic talking avatar can narrate the workflow or present model comparison results, with live word-by-word closed captions in a draggable, resizable panel. Figure 10. A workflow step is highlighted on the canvas as the Avatar Presenter narrates that step.

Tags: artificial intelligence · application · apps & devops · well architected · infrastructureWAR, Azure Advisor, and Us (Azure Arch Diagram Builder): Three Ways to Score an Azure Architecture
Author: Arturo Quiroga, Azure AI services Engineer - Senior Partner Solutions Architect — Microsoft A few days ago I published From Prompt to Production: Building Azure Architecture Diagrams with AI, introducing the open-source Azure Architecture Diagram Builder. One feature got more follow-up questions than any other: the Well-Architected Framework (WAF) validation. Architects from partners and customers — many of whom already use Azure Advisor and the Well-Architected Review — wanted to know exactly what scoring algorithm we use, how it compares to Microsoft's official tools, and whether they should be using all three. This post is that answer. It's a deep dive into how design-time WAF validation works, how Microsoft's two official WAF assessment algorithms work, and where each fits in the architecture lifecycle. TL;DR. Microsoft ships two WAF assessment vehicles — the Well-Architected Review (questionnaire, scored from human answers) and the Azure Advisor score (healthy-resources-÷-applicable-resources weighted per subcategory, with Defender Secure Score for Security and cost-weighted math for Cost). Both require either a human filling in a form or live Azure telemetry. Our app runs at design time on a diagram, before anything is deployed, using a hybrid pipeline: a deterministic rule pre-scan followed by an LLM refinement pass. Same five WAF pillars, different lifecycle stage. Complementary, not competitive. Why design-time validation matters Every cost overrun, reliability gap, and security incident I've ever debugged was cheaper to fix on a whiteboard than in production. Yet most WAF tooling assumes the architecture already exists — either because there are deployed resources to scan (Advisor) or because someone has built enough of it to answer 60 specific questions about it (WAR). That leaves a gap. Between "rough sketch" and "deployed resource group" there is no algorithmic WAF feedback loop. That's the gap the Diagram Builder fills. Microsoft's two official WAF assessment algorithms Before describing our approach, it's worth being precise about what Microsoft already ships, because the term "WAF assessment algorithm" can mean either of two very different things. 1. Azure Well-Architected Review (WAR) — questionnaire-based The Well-Architected Review is a free self-assessment hosted on Microsoft Learn. Aspect Detail Input Human answers to ~60 questions mapped to the WAF pillar checklists Workload variants Core WAR, plus AI/ML, IoT, SAP on Azure, Azure Stack Hub, SaaS, Mission Critical Scoring Derived from the answers — each "no" or unanswered question subtracts from the pillar score Output Per-pillar maturity score + prioritized recommendations + optional Advisor integration Improvement tracking "Milestones" (point-in-time snapshots) When to use Periodic deep reviews; greenfield design baselining; brownfield audits WAR is human-driven. The algorithm is essentially "how many of the recommended practices have you confirmed you do?" — which is exactly the right algorithm when the assessor is the workload team itself. 2. Azure Advisor Score — telemetry-based The Advisor score is the closest thing Microsoft ships to a real, deterministic WAF algorithm. It runs continuously over your deployed Azure resources. The math: Pillar-specific overrides: Security uses Microsoft Defender for Cloud's Secure Score model. Cost weights by retail $ cost of healthy resources, plus age-of-recommendation weighting; postponed/dismissed items are removed from the denominator. Reliability / Performance / Operational Excellence use the healthy-resources ratio above. Key terms: Healthy resource — a deployed resource with no open Advisor recommendation against it for that pillar. Total applicable — resources Advisor was able to evaluate (excludes dismissed/snoozed). Advisor is the right tool once you're in production. It cannot help you before deployment, because there is nothing to count as "healthy" or "applicable." The missing stage: design time Here's the lifecycle, with each tool's domain shaded: Design / Diagram — Diagram Builder validation runs here. Operate / Observe — Azure Advisor runs here continuously. Periodic Review — WAR runs here, typically quarterly or at major milestones. These three stages are sequential and complementary. Our app does not replace Advisor or WAR — it adds a feedback loop earlier in the lifecycle, where corrections are cheapest. How design-time validation works in the Azure Architecture Diagram Builder The validator is a two-phase hybrid pipeline: deterministic local rules first, then LLM refinement. The full source lives in three files: src/services/architectureValidator.ts — orchestrator and prompt src/services/wafPatternDetector.ts — topology + service rule engine src/data/wafRules.ts — the rule knowledge base Phase 1 — Deterministic rule pre-scan (~1 ms, no LLM) When you click Validate Architecture, the validator runs a fully client-side rule engine against the diagram's services, connections, and groups. There are two kinds of rules: Architecture-pattern rules These fire when a topology anti-pattern is detected: Pattern Detection trigger single-region No global LB (Traffic Manager / Front Door) with ≥3 services single-database Exactly one database service, no replication signal no-cache Compute + database present, no Redis/CDN no-monitoring No Azure Monitor / App Insights / Log Analytics no-identity No Microsoft Entra ID no-waf Public web tier without WAF / Front Door / App Gateway direct-db-access An edge from a frontend service directly into a database no-key-vault 4+ services and no Key Vault no-backup Database present, no Azure Backup / Recovery Services no-api-gateway 2+ compute services and no APIM / App Gateway / Front Door Service-specific rules Every service in the in the generated Azure Architecture diagram is matched against SERVICE_SPECIFIC_RULES by normalized type — App Service, Functions, AKS, Cosmos DB, SQL Database, Storage, Key Vault, and 22 more. The knowledge base at a glance Metric Count Total rules 73 Architecture-pattern rules 10 Service-specific rules 63 Distinct Azure services covered 29 Rules tagged Reliability 18 Rules tagged Security 34 Rules tagged Cost Optimization 5 Rules tagged Operational Excellence 7 Rules tagged Performance Efficiency 9 The preliminary score Each finding has a severity, and severity drives a fixed point deduction from a starting score of 100: Severity Deduction critical −12 high −7 medium −3 low −1 Result is floored at 10 (so even a deliberately bad architecture scores at least 10) and ceilinged at 95 (no findings ≠ perfect — there's always something the model might still catch). This is the deterministic baseline before the LLM ever sees the architecture, and it's what makes the pipeline reproducible. Phase 2 — LLM contextual refinement The pre-scan output, the topology, and the optional natural-language description are folded into a focused prompt sent to one of seven Azure OpenAI models (GPT-5.1 through 5.4, GPT-5.x Codex variants, DeepSeek V3.2 Speciale, Grok 4.1 Fast). The system prompt gives the model explicit scoring guardrails: Score based on what IS present, not what COULD be added. A well-connected architecture with appropriate services should score 60–80. Score below 50 only for critical gaps (no auth, no monitoring, single points of failure). Findings are improvement suggestions, not reasons to penalize the score severely. The model returns strict JSON: { "overallScore": 0-100, "summary": "2–3 sentence assessment", "pillars": [ { "pillar": "Reliability | Security | Cost Optimization | Operational Excellence | Performance Efficiency", "score": 0-100, "findings": [ { "severity": "critical | high | medium | low", "category": "...", "issue": "...", "recommendation": "...", "resources": ["service-name-1", "service-name-2"], "source": "rule-based | ai-analysis" } ] } ], "quickWins": [ /* same shape as findings */ ] } Two things to call out: Every finding is tagged rule-based or ai-analysis . That tag is the credibility lever. You can always see what the deterministic engine produced versus what the model contributed on top. If you don't trust the AI layer, you can ignore it entirely — the rule layer still stands. The LLM is given pattern hints, not the entire rule catalog. The prompt stays small and focused, which is roughly 3–5× faster and cheaper than asking the LLM to do everything from scratch. What the user sees On every run the modal reports: Overall WAF score (0–100) Per-pillar score × 5 (0–100 each) Severity breakdown — counts of critical / high / medium / low across all findings Quick wins — high-impact, low-effort items the model surfaces separately Hybrid metadata — local findings count, patterns detected, KB rules used, preliminary score, local elapsed ms AI metrics — model used, reasoning effort, prompt/completion/total tokens, elapsed time App Insights telemetry — an Architecture_Validated event with model, overall score, finding count, elapsed time Worked example Take this prompt, which I've used in demos with partners: "A multi-region web application: Azure Front Door in front of two App Service instances in West US 2 and East US 2, both reading from an Azure SQL Database with geo-replication, with Application Insights for telemetry. No Entra ID, no Key Vault." After generation, Validate Architecture runs: Phase 1 — pre-scan (deterministic), ~1 ms Patterns detected: no-identity , no-key-vault Findings produced: 8 (1 critical, 1 high, 3 medium, 3 low) Preliminary score: 100 − 12 − 7 − (3×3) − (1×3) = 69 Phase 2 — LLM refinement, ~6–9 s depending on model The model accepts the two pattern hints, validates them in context, and adds three more findings of its own: Finding Source Pillar Severity No Microsoft Entra ID for authentication rule-based Security critical No Key Vault for secret management rule-based Security high App Service slots not used for safe deploys ai-analysis Operational Excellence medium SQL DB geo-replication present but RTO/RPO not documented ai-analysis Reliability medium No CDN for static assets behind Front Door ai-analysis Performance Efficiency low Final scores returned by the model: Pillar Score Reliability 78 Security 52 Cost Optimization 80 Operational Excellence 70 Performance Efficiency 75 Overall 71 The Security score is the lowest because two of the highest-severity findings landed there — exactly what a human reviewer would flag first. Multi-model comparison Because the deterministic floor is identical across runs, the Validation Comparison view becomes a fair shootout of what each LLM adds on top of the same baseline. The same diagram is scored by all seven models, and the UI surfaces: Overall score per model Per-pillar score per model Severity-count deltas Number of ai-analysis findings each model contributed Quick wins each model identified This is genuinely useful for two reasons. First, it shows that LLM scores vary — typically by ±5–10 points on the same architecture — which is exactly why we publish the rule-based vs ai-analysis tag. Second, it lets architects pick the model whose review style matches their own. How we align with Microsoft's algorithms Alignment point What it means Same five pillars Identical names and scope to the official WAF Same source material Rules derived from WAF docs and Azure Architecture Center service guides Severity-graded findings Map conceptually to Advisor's high/medium/low impact recommendations Per-pillar + overall scoring Mirrors WAR/Advisor output shape, so the results feel familiar Where we deliberately differ — and why Concern Microsoft Diagram Builder Why we differ Needs deployed resources Advisor: yes No — works on a diagram We're a design-time tool; the architecture doesn't exist yet Needs human Q&A WAR: yes No — derived from the diagram One-click validation inside the design flow Healthy/Applicable ratio Advisor: yes No No resource-health signal exists pre-deployment Subcategory fixed weights Advisor: yes No explicit weights Severity is the de-facto weight (12/7/3/1) Defender Secure Score for Security Advisor: yes No Defender requires deployed resources Cost-weighted scoring Advisor: yes No (separate Cost Estimation feature) Cost is a separate pipeline in our app AI/LLM refinement Neither Yes Catches context-specific issues a static catalog misses, and explains findings in natural language Multi-model comparison Neither Yes Lets architects see scoring variance across models Honest limitations I'd rather you hear these from me than discover them in production: LLM scores drift. ±5–10 points across models on the same diagram is normal. Treat the score as directional, the findings as actionable. The rule-based tag is your anchor. No live telemetry. We can't know if your App Service is actually using availability zones — only that you have App Service in the diagram. Advisor will tell you the truth post-deployment. Generic ruleset. No specialized workload branches yet (AI/ML, IoT, SAP, SaaS). WAR has those. No milestone tracking. Each validation run is independent. Compare runs manually using the Validation Comparison view. Rule coverage is finite. 29 services and 73 rules is a strong start but not exhaustive — the LLM layer exists in part to compensate for that gap. How to use all three together A lifecycle that actually works: Design — Use the Diagram Builder to sketch the architecture and validate at design time. Iterate until the per-pillar scores look reasonable and the critical/high findings are addressed. Deploy — Generate Bicep from the diagram, deploy, and let Azure Advisor start scoring real resources. Operate — Use Azure Advisor continuously. Use Defender Secure Score for security posture. Periodic review — Run a Core WAR every quarter or at major milestones to capture the things only humans know (business context, tradeoffs, planned debt). None of these three replace the others. They cover different stages of the same loop. What's next A few things on the roadmap I'd love feedback on: Milestone tracking so design-time scores can be compared over time the way WAR milestones work. Workload-specific rulesets mirroring WAR's branches — starting with AI/ML. Direct Advisor handoff — once a diagram is deployed, surface the corresponding Advisor recommendations in the same UI to close the loop.

Configure DNS forwarding for Azure NetApp Files
This post has been written with the collaboration of Rizul Khanna Applies to: Azure NetApp Files — SMB, dual-protocol, and NFSv4.1 Kerberos volumes deployed in hub-spoke or Azure Virtual WAN topologies using an external private DNS forwarder. Overview Azure NetApp Files (ANF) has a hard dependency on DNS for all volume types that integrate with Active Directory (AD): SMB, dual-protocol (SMB + NFS), and NFSv4.1 with Kerberos. Unlike most Azure PaaS services, ANF does not use Azure Private Link and has no privatelink.* zone. Its volumes attach directly to a delegated subnet, and their hostnames are registered into AD-integrated DNS via Secure Dynamic DNS (DDNS). This architecture means DNS design decisions for the ANF delegated subnet are fundamentally different from those that apply to storage accounts, SQL databases, or other services that use private endpoints. This article documents what DNS resolution ANF requires, how to correctly configure an external private DNS forwarder in hub-spoke and Virtual WAN deployments, and the specific undocumented requirements that cause volume creation failures and SMB permission errors in practice. Several requirements covered here are not present in the official Azure NetApp Files documentation and have been identified through field support cases. ANF does not inherit the VNET DNS server setting. It queries only the two DNS server IPs configured in the Active Directory connection on the NetApp account. This is not documented in the ANF networking or AD connection articles. The VNET DNS server setting is irrelevant to ANF volume creation and AD join behavior — only the AD connection DNS IPs matter. Architecture overview The following diagram shows the two separate DNS paths that must be configured when ANF is deployed in a hub-spoke or Virtual WAN topology with an external private DNS forwarder. The client resolution path (VNET DNS setting) and the ANF internal resolution path (AD connection DNS fields) are distinct and must not be conflated. Note: ANF AD connection DNS IPs must point to the external DC IPs directly — not to the private DNS forwarder. The forwarder handles client-side resolution only and must have both forward and reverse rulesets for the AD domain. Figure 1: DNS resolution paths for ANF with an external private DNS forwarder. Client VMs use the forwarder (VNET DNS setting). ANF uses the external AD DC IPs directly (AD connection DNS fields). Both forward and reverse lookup rulesets are required on the forwarder. What DNS must provide for Azure NetApp Files Outbound resolution — ANF querying DNS ANF must be able to resolve the following records from the DNS IPs specified in the AD connection: AD domain controller SRV records: _ldap._tcp.<site>._sites.dc._msdcs.<domain>, _kerberos._tcp.dc._msdcs.<domain>, and site-scoped equivalents Kerberos KDC records: _kerberos._tcp.<domain> and _kerberos-master._tcp/udp.<domain> DC A records: Forward lookup for each DC hostname to its IP PTR (reverse) records: IP-to-hostname for each DC — required for dual-protocol volume creation, NFSv4.1 Kerberos, LDAP-over-TLS certificate validation, and NTFS ACL operations on SMB shares. Note: _kerberos-master._tcp and _kerberos-master._udp SRV records are not created automatically by Active Directory DNS. They must be added manually in the DNS zone. Their absence causes Kerberos failures that do not clearly identify DNS as the root cause. This requirement is not documented in any ANF article. ANF performs Secure Dynamic DNS (DDNS) using GSS-TSIG to register SMB and dual-protocol volume hostnames in AD DNS. This requires that the DNS IPs in the AD connection belong to Microsoft AD-integrated DNS servers. External private DNS forwarders (Infoblox, BIND, Unbound, and similar appliances) do not support GSS-TSIG and will silently discard DDNS updates — volume hostnames will not appear in DNS and SMB mounts will fail. No error is surfaced in the ANF portal or activity log when DDNS is silently dropped. Inbound resolution — clients resolving ANF hostnames SMB and dual-protocol volumes are accessed via a hostname of the form <smb-prefix>-XXXX.<ad-dns-domain>, where the four-character suffix is assigned by ANF and cannot be overridden. Clients must resolve this hostname to the volume IP via the VNET DNS server setting, which in enterprise environments points to the external private DNS forwarder. The forwarder must have a forward lookup ruleset for the AD domain pointing to the external DC IPs. NFSv3 mounts use the volume IP directly and do not require hostname resolution. Note: NFSv3 volume creation success does not indicate SMB readiness. NFSv3 mounts use the volume IP directly and require no AD join, Kerberos exchange, or reverse DNS. SMB and dual-protocol volumes require all three. Using NFSv3 as a connectivity proxy during SMB troubleshooting produces false confidence. This distinction is not documented in ANF troubleshooting guidance. Configuring the external private DNS forwarder The two DNS paths — client resolution vs ANF internal In environments using an external private DNS forwarder (Infoblox, BIND, Windows DNS VM, or similar appliance), two distinct DNS paths must be kept separate. The VNET DNS server setting governs client resolution of ANF SMB hostnames and should point to the external forwarder. The ANF AD connection DNS fields govern ANF's own resolution of DCs and DDNS registration and must point directly to writable Microsoft AD-integrated DC IPs. DNS Path Used By Correct Target Client resolution (VNET DNS setting) VMs, Citrix, application servers resolving ANF SMB hostnames. External private DNS forwarder, which forwards AD zone queries to external DC IPs ANF internal resolution (AD connection DNS fields) ANF service — DDNS, Kerberos, LDAP, SRV lookup Writable AD-integrated external DC IPs directly — not the forwarder Required rulesets on the external private DNS forwarder The external private DNS forwarder must have both of the following rulesets configured. Missing either one produces failures that are difficult to diagnose because forward DNS tests pass while the actual failure occurs in a different path. References: Understanding Private DNS resolver endpoints & rulesets How to create Private Reverse DNS records Forward lookup ruleset Forward all queries for the AD domain to the external DC IPs: Zone: ad.contoso.com Targets: <DC-IP-1>:53, <DC-IP-2>:53 (writable external DC IPs) Reverse lookup ruleset (most commonly missing) Forward reverse lookup queries for the DC IP range to the external DC IPs: Zone: <reverse-octets>.in-addr.arpa. Targets: <DC-IP-1>:53, <DC-IP-2>:53 (same external DC IPs) Critical: The reverse lookup ruleset is the most commonly missing configuration item and causes a failure that forward DNS tests do not detect. Without it, Windows clients cannot resolve DC IPs to hostnames. This produces the following error when provisioning NTFS permissions on an ANF SMB share: 'The program cannot open the required dialog box because it cannot determine whether the computer named is joined to a domain.' All connectivity tests pass. Forward DNS passes. The volume was created successfully. Only the reverse lookup fails — and only when NTFS ACL operations are attempted. This failure mode and its root cause are not documented in any ANF article. GSS-TSIG constraint — why the forwarder cannot be in the ANF AD connection External private DNS forwarders (including Infoblox, BIND, Unbound, and third-party appliances) do not support GSS-TSIG, the protocol ANF uses to securely register SMB volume hostnames into AD DNS. If a forwarder IP is placed in the ANF AD connection DNS fields, ANF sends DDNS update packets to the forwarder, which discards them silently. The volume hostname never appears in DNS. Clients cannot mount by name. No error is returned in the ANF portal. The correct design: external DC IPs in the ANF AD connection, external private DNS forwarder as the VNET DNS server for clients only. Role of 168.63.129.16 168.63.129.16 is the Azure-provided internal resolver. It should be configured as the upstream forwarder target on the external private DNS forwarder for all queries not covered by AD or other conditional forwarders. This allows Azure-hosted DNS zones (such as any privatelink.* zones linked to your VNET) to resolve correctly through the forwarder. IMPORTANT: 168.63.129.16 must never be placed in the ANF AD connection DNS fields. It is not AD-aware, cannot answer SRV queries for your domain, cannot accept DDNS updates, and is unreachable from on-premises over ExpressRoute or VPN. Its correct position is as an upstream target on the external private DNS forwarder — not in ANF's AD connection. This is not stated anywhere in the ANF documentation set. DNS forwarder pattern comparison Pattern DDNS Support Reverse DNS Ops overhead Best Fit AD DNS on DCs + upstream 168.63.129.16 Yes, Native Yes, if reverse zones on DC's Medium Default; simplest topology External private DNS forwarder (VMs only) + external DC IPs in ANF AD connection Yes (ANF bypasses forwarder) Yes, if reverse ruleset on forwarder. Medium Enterprise with existing DNS infrastructure External DNS forwarder in ANF AD connection (incorrect) No — DDNS silently dropped N/A — config is wrong High Not supported Azure DNS Private Resolver in ANF AD connection (incorrect) No — DDNS not accepted N/A — config is wrong High Not supported Azure Virtual WAN considerations When ANF is deployed in a spoke VNET connected to an Azure Virtual WAN hub, a routing requirement applies that directly causes Kerberos and LDAP failures — which appear to be DNS or AD failures — when not addressed. This is one of the most common misdiagnoses in ANF deployments using Virtual WAN with NVA inspection. ANF subnet prefix must be in Routing Intent additional prefixes Azure Virtual WAN with Routing Intent routes private traffic through an NVA or Azure Firewall in the hub. For return traffic from external AD domain controllers to reach the ANF data plane IP, the hub must have an explicit routing entry for the ANF delegated subnet prefix. If the ANF delegated subnet is a /26 inside a larger VNET (/21 or /16), the broader VNET prefix alone is not sufficient — the specific /26 must be added explicitly. Action Required: In Azure Virtual WAN: Hub -> Routing -> Routing Intent -> Private Traffic -> Additional Prefixes. Add the ANF delegated subnet prefix (for example, 10.x.x.0/26) explicitly. Without this, Kerberos and LDAP reply traffic from external domain controllers is dropped before reaching the ANF data plane. The symptom is TCP port 88 connects succeeding followed by KRB5_KDC_UNREACH — which looks like a Kerberos or DNS problem but is a routing problem. Use availability zone switching to surface detailed error messages When ANF volume creation fails with the generic 'context deadline exceeded' error from the XMLrequest_filer endpoint, the error does not identify root cause. Redeploying the volume to a different availability zone (AZ1 to AZ2, or AZ2 to AZ3) forces a different backend assignment and consistently produces a more descriptive error that distinguishes routing failures (KRB5_KDC_UNREACH) from Kerberos authentication failures, DNS lookup failures, and LDAP errors. TIP: If the detailed error shows 'Successfully connected to ip <DC-IP>, port 88 using TCP' followed by 'Cannot contact any KDC for requested realm', the outbound path works but reply packets are dropped — this is a routing problem, not a DNS or Kerberos problem. Check vWAN Routing Intent, NVA firewall rules, and UDRs for the ANF subnet prefix. This diagnostic technique is not documented in ANF troubleshooting guidance. Required DNS records The following records must exist in the AD DNS zone served by the external DC DNS servers and must be resolvable from the ANF delegated subnet. Records marked * are not created automatically by AD DNS and must be added manually. Forward lookup zone Record Type Notes _ldap._tcp.dc._msdcs.<domain> SRV Domain-wide DC discovery _kerberos._tcp.dc._msdcs.<domain> SRV Domain-wide KDC discovery _ldap._tcp.<site>._sites.dc._msdcs.<domain> SRV Site-scoped — preferred when AD site is specified in ANF _kerberos._tcp.<site>._sites.dc._msdcs.<domain> SRV Site-scoped Kerberos _kerberos-master._tcp.<domain> * SRV NOT auto-created by AD DNS — must be added manually _kerberos-master._udp.<domain> * SRV NOT auto-created by AD DNS — must be added manually <dc-hostname> A Forward A record for each external DC in the AD site <anf-smb-hostname> A Registered by ANF via DDNS — must not be scavenged or blocked Reverse lookup zone (<reverse-octets>.in-addr.arpa) Record Type Notes PTR for each external DC IP PTR Required for dual-protocol, NFSv4.1 Kerberos, LDAP-over-TLS, and NTFS ACL operations PTR for each ANF volume IP * PTR Required for NFSv4.1 Kerberos reverse-lookup clients — create manually or via DDNS if supported How ANF internally fails when reverse DNS is missing When the reverse DNS ruleset is absent from the external private DNS forwarder, the failure does not surface as a DNS error in the ANF portal. Instead, it propagates through ANF's internal security daemon (secd) and presents as a generic InternalServerError or a Kerberos authentication failure. Understanding the internal failure chain explains why reverse DNS is non-negotiable and why the symptom is so misleading. The secd service list mechanism ANF uses an internal process called secd (Security Daemon) to manage all Active Directory communication — Kerberos ticket exchange, LDAP binds, and DC discovery. secd maintains a service list of discovered DCs. When a DC communication attempt fails for any reason, secd marks that DC as UNUSABLE and records a forgive time after which it will retry. If all DCs in the service list are simultaneously marked UNUSABLE, secd returns RESULT_ERROR_SECD_NO_SERVER_AVAILABLE, which propagates to the portal as InternalServerError. The reverse PTR lookup inside secd A critical and undocumented behavior: before secd completes a SASL/GSSAPI bind to an LDAP server, it performs a reverse PTR lookup of the DC's IP address. This lookup is used to validate the DC identity as part of Kerberos mutual authentication. If the PTR lookup fails — because the external private DNS forwarder has no reverse ruleset for the DC IP range — secd logs the failure and marks that DC UNUSABLE immediately, even though TCP connectivity on ports 88 and 389 succeeded. The following is the exact failure sequence from ANF backend logs when reverse DNS is absent: Stage 1 — TCP connects succeed, PTR lookup fails Successfully connected to ip 10.x.x.60, port 389 using TCP Entry for host-address: 10.x.x.60 not found in the current source: FILES Source: DNS unavailable. Entry for host-address: 10.x.x.60 not found in any of the available sources secd successfully opens the TCP connection to the DC on port 389 (LDAP), then immediately attempts a reverse lookup of that IP. The forwarder has no reverse ruleset, so DNS returns NXDOMAIN. secd logs 'DNS unavailable' and proceeds to mark the DC UNUSABLE. Stage 2 — GSSAPI bind fails as a consequence Unable to SASL bind to LDAP server using GSSAPI: Local error Unable to connect to LDAP (Active Directory) service on dc01.ad.contoso.com (Error: Local error) Because the PTR lookup failed, secd cannot complete the GSSAPI mutual authentication context. The 'Local error' is not a Kerberos configuration problem — it is the direct result of the identity validation step failing due to missing reverse DNS. Stage 3 — All DCs marked UNUSABLE 10.x.x.27 UNUSABLE Wed Apr 8 00:19:24 2026 10.x.x.28 UNUSABLE Wed Apr 8 00:19:24 2026 10.x.x.29 UNUSABLE Wed Apr 8 00:19:25 2026 10.x.x.30 UNUSABLE Wed Apr 8 00:19:25 2026 ... (all DCs in the service list) secd cycles through every DC in the discovered service list. Each DC fails the same PTR lookup. Each is marked UNUSABLE. Once the list is exhausted: Stage 4 — Service list exhausted, error propagates No servers in the service list which aren't marked bad Unable to select any server in the current serviceList RESULT_ERROR_SECD_NO_SERVER_AVAILABLE:6940 No servers available for MS_LDAP_AD, domain: ad.contoso.com This internal error code propagates up through the ANF volume creation stack and is presented to the operator as the generic 'context deadline exceeded (Client.Timeout exceeded while awaiting headers)' error in the portal. The actual cause — missing PTR records — is completely obscured. Stage 5 — Kerberos pre-auth error (secondary, misleading) Received error from KDC: -1765328359 / Additional pre-authentication required This Kerberos error code (KRB5KDC_ERR_PREAUTH_REQUIRED) appears in logs and can mislead investigation toward Kerberos configuration, encryption type mismatches, or clock skew. It is a downstream consequence of the failed PTR-based GSSAPI context — not a root cause. Chasing this error without first verifying reverse DNS is a common and time-consuming dead end. KEY INSIGHT: The complete failure chain is: missing reverse PTR ruleset on DNS forwarder → secd PTR lookup returns DNS unavailable → GSSAPI mutual auth cannot complete → DC marked UNUSABLE → all DCs exhausted → InternalServerError at portal. TCP connectivity on ports 88 and 389 succeeds at every stage. Only the PTR lookup fails. This is why all standard connectivity tests pass and the issue remains invisible until reverse DNS is specifically tested. Why this failure is invisible to standard troubleshooting ? Standard ANF DNS troubleshooting checks forward SRV records, forward A record resolution, and TCP port connectivity to DCs. All of these pass when only the reverse ruleset is missing. The secd PTR lookup is an internal step that occurs after TCP connectivity is confirmed and is not tested by any of the standard nslookup or Test-NetConnection commands used during initial validation. The only reliable way to surface this failure without access to backend logs is to explicitly test reverse PTR resolution from the ANF VNET — as documented in the verification section below. Verify DNS configuration Run the following commands from a test VM in the same VNET as the ANF delegated subnet. Use the external private DNS forwarder IP for client-side tests and an external DC IP for ANF-side tests. Forward SRV lookup — site-scoped nslookup -type=SRV _ldap._tcp.<SITE>._sites.dc._msdcs.<domain> <forwarder-IP> nslookup -type=SRV _kerberos._tcp.<SITE>._sites.dc._msdcs.<domain> <forwarder-IP> Forward SRV lookup — domain-wide nslookup -type=SRV _ldap._tcp.dc._msdcs.<domain> <forwarder-IP> nslookup -type=SRV _kerberos._tcp.dc._msdcs.<domain> <forwarder-IP> Reverse PTR lookup — use the external forwarder IP nslookup <external-DC-IP> <forwarder-IP> Expected output: Server: <forwarder-IP> <reverse-arpa> name = dc01.ad.contoso.com. If reverse lookup returns NXDOMAIN or times out while forward lookup succeeds, add the reverse DNS ruleset to the external private DNS forwarder. This is the most common cause of NTFS permission failures after a volume is successfully created. Port connectivity from ANF VNET Test-NetConnection -ComputerName <external-DC-IP> -Port 88 # Kerberos Test-NetConnection -ComputerName <external-DC-IP> -Port 389 # LDAP Test-NetConnection -ComputerName <forwarder-IP> -Port 53 # DNS Common issues and resolutions Symptom Likely cause Resolution InternalServerError: context deadline exceeded (XMLrequest_filer) Generic ANF backend timeout — routing or Kerberos root cause not visible at this level Switch deployment availability zone for a detailed error. Check vWAN Routing Intent for ANF /26 prefix. KRB5_KDC_UNREACH — TCP port 88 connects succeed but auth fails Return traffic from external DCs dropped before reaching ANF NIC — routing issue, not DNS Add ANF subnet /26 to vWAN Hub Routing Intent > Additional Prefixes > Private Traffic 'Cannot determine whether the computer is joined to a domain' — NTFS permissions Reverse DNS (PTR) lookup failing on external forwarder for DC IPs Add reverse lookup ruleset to external private DNS forwarder: <reverse-zone>.in-addr.arpa. > external DC IPs DDNS fails — SMB hostname not in DNS after volume creation ANF AD connection DNS IPs point to external forwarder — GSS-TSIG not supported by forwarder Set AD connection DNS IPs to writable Microsoft AD-integrated external DC IPs directly 'Failed to validate LDAP configuration' during dual-protocol creation Missing PTR records for external DCs, or reverse zone unreachable Add PTR records for all external DCs. Verify reverse ruleset is present on the forwarder. NFSv4.1 Kerberos: 'Cannot determine realm for numeric host address' Missing PTR for ANF volume IP or external DC IPs Add PTR records for ANF volume IPs and all external DC IPs in the reverse zone. SMB hostname resolves on-premises but not from Azure VMs External private DNS forwarder missing forward ruleset for AD zone, or targeting wrong DC IPs Verify forward ruleset is present and targeting reachable writable external DC IPs. Volume creation fails after external DC IP change External DNS forwarder (especially BIND) caching stale DC IPs — default TTL up to 7 days Flush forwarder cache. Set short TTLs on DC A records. Consider Microsoft AD-integrated DNS for AD zones. Summary of key requirements: ANF AD connection DNS IPs must point to writable Microsoft AD-integrated DNS servers (external DC IPs) — not the external private DNS forwarder, not Azure DNS Private Resolver, not 168.63.129.16. The external private DNS forwarder must have both a forward ruleset (AD domain > external DC IPs) and a reverse ruleset (in-addr.arpa. zone for DC IP ranges > external DC IPs). The reverse ruleset is required for NTFS ACL operations on SMB shares and is not mentioned in ANF documentation. 168.63.129.16 is the upstream forwarder target on the external DNS forwarder — not a target in the ANF AD connection. It is unreachable from on-premises and is not AD-aware. External private DNS forwarders (Infoblox, BIND, Unbound) do not support GSS-TSIG. Placing a forwarder IP in the ANF AD connection causes silent DDNS failure with no portal error. In Virtual WAN deployments, add the ANF delegated subnet /26 to the hub Routing Intent under Additional Prefixes for Private Traffic. The broader VNET prefix alone is not sufficient. NFSv3 volume creation success does not indicate SMB readiness — NFSv3 uses the IP directly and bypasses AD, Kerberos, and reverse DNS. _kerberos-master SRV records are not created automatically by AD DNS and must be added manually. DNS scavenging should be disabled on zones containing ANF records, or records pre-created as static entries, as ANF does not aggressively refresh DDNS registrations. When volume creation fails with a generic 'context deadline exceeded' error, switch the deployment availability zone before deep troubleshooting to surface a more descriptive error.

The “Why” Do you manage data in a complex multi-cloud environment? Are you struggling with data silos, evolving regulations, and the pressure to maintain control and compliance across on-prem and multiple clouds? Do you ever wish an intelligent assistant could help shoulder the load of data governance? If so, I can relate. Let me tell you a story that might sound familiar. Meet Mark (pictured above). He is a data governance officer at Contoso (a fictional but very representative enterprise). Mark’s day job is ensuring data governance and compliance across his company’s vast hybrid cloud estate – think around ~2 million data assets sprawled across 12+ datacenters on-premises and in different public clouds. Regulatory requirements are constantly shifting. Customer data is increasingly sensitive. Each department and region has its own way of doing things. Mark is fighting an uphill battle with data silos and disconnected cloud operations. He bounces between a patchwork of tools – spreadsheets, cloud consoles, governance portals – trying to answer basic questions: Where is our data? Who’s using it? Are we in compliance? Armed with an old desk calculator and a pile of paper-based reports (a perfect 1990s backdrop), he is dealing with the data around him that has exploded in volume and complexity. What if Mark had a single pane of glass. The glass that reflects and acts. It reflects your governance state and enforces compliance – a self-hydrating pane of glass accompanied by a conversational AI. And he’s not alone. We’re all living in a data overload era. Every day, organizations generate and ingest more information than ever before. Transistors and mainframes gave way to the internet boom of the ’90s, then an explosion of mobile devices in the 2000s, social media in the 2010s, and now widespread cloud computing – all funneling data into our systems at an exponential rate. On top of that, a new wave of AI and conversational interfaces has arrived here in the mid-2020s, making data more accessible but also increasing expectations for real-time insight. It’s no wonder modern IT leaders feel overwhelmed. But these challenges are also opportunities. The way I see it, the incredible growth of data and cloud capabilities means we have a chance to reimagine data governance. The fact that I’m writing about this right now is no coincidence. My customers are looking to resolve problems in this space. In my conversations with them, I hear the same needs: We want better governance, more visibility, streamlined oversight… and cherry on top, we want it in an “agentic” fashion. In other words, they want to delegate the grunt work to the platform toolset augmented by AI, so they can focus on higher-value tasks. The “What” That vision – agentic data governance with hybrid cloud flexibility – became the driver for this work. This is a modular solution, and you have these building block style components (cloud services, governance tools, AI agents), which you can snap them together into an intended solution. Think of it as a jumpstart kit for continuous data governance across multiple clouds, with autonomous (“agentic”) assistance baked in that you can leverage and build upon. It’s not the final, productized solution – more a vision of what’s possible. Contoso’s Requirements These are the high-level requirements from Contoso: Data governance across clouds under one roof A single pane of glass dashboard consolidating reporting on the 5 governance domains: o Visibility on data residency and lineage o PII (Personally Identifiable Information) must run on a CC (Confidential Compute) o Security software (Defender) compliance o Resource tagging compliance (foundational for a good governance posture) o OS updates compliance Ability to enforce compliance in an agentic manner with a human in the loop Agentic enforcement of compliance pertaining to residency and confidential compute Solution – The breakdown The solution is comprised of 8 modules addressing these requirements. These solution modules are: Foundational (Landing zones, Data Sources, Operational setup, Policies, etc.) Dashboard Hydration + Agentic Reporting – Residency Compliance Dashboard Hydration + Agentic Reporting – Confidential Compute for PII Compliance Dashboard Hydration + Agentic Reporting – MS Defender Compliance Dashboard Hydration + Agentic Reporting – Resource Tag Compliance Dashboard Hydration + Agentic Reporting – OS Updates/Patch Compliance Enforce Compliance via Copilot Agent - Residency Compliance Enforce Compliance via Copilot Agent – CC PII Compliance Solution – The architecture view These are the main technical components that make up the solution architecture: Data sources of all shapes and sizes on the left, governed by the native Azure or the Arc plane. Additional Azure services across the bottom layer for the foundational governance posture Microsoft Purview, in the top middle, as the unified data governance platform Microsoft Fabric, in the bottom middle, as the end-to-end ingestion and analytics platform Microsoft Power Platform, on the right, as the low code/no code business flow and the copilot agent experience Solution – The end user view So how does Mark see this solution as a data governance officer? He doesn’t see all the intricacies of the solution integration and the logic execution. He sees two things: A Power BI dashboard running on Microsoft Fabric with A compliance dashboard with an overall score in each of the five compliance domains alongside scores for each of the data products across these domains Additional reporting views for more granular reporting Fabric-based pipeline that hydrates the underlying semantic models from various sources to keep the reports fresh and current A Copilot agent (in Teams) for both: Reporting on all compliance domains Enforcing in-scope compliance across selected domains The agent takes care of it - queries Fabric’s semantic model, calls Azure Function endpoints, updates Purview glossary terms, applies Azure tags, and sends Teams notifications. The “How” – Residency Compliance Let’s pick a few modules to walk through how these solution modules work together to give a cohesive agentic governance experience to Mark. It’s Monday morning, and Mark logs into the Contoso governance portal with a cup of coffee in hand. Instead of a dozen browser tabs, he has two main tools opened: the Data Governance Dashboard and the Contoso Governance Copilot agent. To address some inquiries that came as an assigned action to him, he interacted with the agent. During this interaction, not only did he validate if there were any residency missing in the unified data governance platform (Purview), but he was also able to address a mismatch between Purview and Azure resource, based on the designed principles. Here is the snippet of the chat: Now, under the hood, several components have worked on behalf of the agent in performing this governance checking and applying the necessary course of action: Even before Mark's conversation with the agent, an ongoing hydration process keeps the Fabric Power BI dashboard up to date. Dashboard Hydration + Agentic Reporting – Residency Compliance A Fabric notebook runs the residency scorecard code block through a pipeline. It reads two Lakehouse tables containing latest residency information from Purview and the approved region list Then, the notebook gets a Microsoft Entra bearer token Once acquired, the notebook then calls an Azure Function endpoint This endpoint, then searches for the Azure resources associated with the data products in Purview using an Azure resource tag. The notebook then compares the declared Purview residency with the approved region list and the associated resource’s region The notebook then calculates the final 0 / 25 / 50 / 75 / 100 residency compliance score and a reason. For example: A data product without an associated Azure resource gets a 0, while a data product whose residency in Purview is an approved region by Contoso, and also matches with the associated Azure resource, gets a 100. It then writes the results to the relevant residency compliance Lakehouse tables The dedicated compliance table then feeds to the semantic model for reporting The compliance Power BI dashboard is hydrated Enforce Compliance via Copilot Agent - Residency Compliance With the dashboard data regularly updated, the agent follows this logic, the updated reporting data, and the actions at its disposal, during the earlier conversation with Mark : Mark initiates the conversation with the agent The agent calls a Power Automate flow This flow retrieves Purview’s residency information stored in the Fabric semantic model 5, 6, 7 and 8. When Mark asks to investigate further on a data product, the agent carries the conversation using a topic, which then leverages a flow, which uses a Power Automate custom connector to access an Azure Function endpoint. This endpoint then retrieves latest glossary (residency) information about the data product in question, from Purview, and provides a preview back to the user 10, 11, 12, and 13. If the update criteria are met, and if there is no conflict, and with Mark’s blessings, the topic then calls another flow to access the Functions Purview Update endpoint, and make the glossary (residency) update in Purview for that data product The “How” – Confidential Compute for PII Compliance Dashboard Hydration + Agentic Reporting – Confidential Compute for PII Compliance The following snippet shows how Mark addresses the compliance risk with a critical data product (application), S/4 HANA, and performed the necessary compliance actions, such as tagging the associated resources and notifying the data product owners via Teams channel. The following diagram shows the under-the-hood hydration flow for confidential compute compliance: Enforce Compliance via Copilot Agent – CC PII Compliance Finally, the diagram below shows how Mark’s conversation flows through the main solution components: Outcome Stepping back, what did we accomplish for Mark and Contoso? We turned an onslaught of governance challenges into an opportunity to modernize how data is managed. This gave Mark: Centralized Visibility into data assets across the landscape through Purview and a unified dashboard Proactive compliance enabled with automated checks - controlled with Purview exports and Fabric pipeline schedules And compliance enforcement using an agent Hybrid Cloud Consistency. By using Azure Arc and a foundational data plane management setup Reduced Operational overhead with agentic reporting and compliance Though the solution is comprised of wide variety of components/services, it is built from standard building blocks and is relatively simple to implement. In total, the solution combined around a dozen Azure services and over 40 distinct components (from Purview catalogs to data pipelines, to custom functions and flows). You can choose to implement some or all the compliance domains. Or, better yet, build upon and create new domains and pave new paths. Wrap-up I believe many enterprises could take a similar journey. If you’re facing these issues, consider this an invitation to think differently about data governance. Start with the pieces you already have – your own building blocks of cloud services and data – and imagine what you could build. Chances are that a lot of the heavy lifting can be orchestrated with today’s technology. And with the rise of AI copilots, the dream of agentic data governance – where your policies are continuously enforced by smart agents – is no longer science fiction. It’s here, right now, waiting for you to take it for a spin.

Many organizations are balancing near-term continuity for VMware-based workloads with longer-term cloud modernization goals – all while managing cost, security, and resiliency. Azure VMware Solution (AVS) is built for this moment: a Microsoft-managed service verified by VMware that enables running VMware Cloud Foundation (VCF) workloads (vSphere, NSX-T, vSAN, HCX) on dedicated Azure infrastructure. It gives organizations a practical way to move or extend VMware environments into Azure while maintaining operational consistency and leveraging the skills of existing VMware teams. To help leaders quantify the potential value of this approach, Microsoft commissioned Forrester Consulting to conduct The Total Economic Impact™ (TEI) of Microsoft Azure VMware Solution (March 2026). The study models the financial impact over three years and risk-adjusts results. Access the full study here: aka.ms/AVS-TEI Here’s what the study found and how IT leaders can use it as a framework for decision-making: Topline results from the study Forrester’s risk-adjusted financial analysis for a composite organization 1 found: 341% ROI over three years 2 $5.6M net present value (NPV) 3 <6 months payback 4 These metrics are meaningful on their own, but the bigger story for leadership is where the value comes from: improved operational stability, reduced infrastructure costs driven by data center exit and hardware refresh avoidance, and the ability to redeploy skilled IT resources from maintenance to modernization. The customer journey: why organizations turn to AVS AVS offers a bridge: Lift and shift VMware workloads into Azure without forcing immediate re-platforming then, modernize at a pace aligned to business priorities. In the study, Forrester interviewed decision-makers with experience using AVS. Interviewees described common challenges that led them to invest in AVS, including: Fragmented systems that complicated and slowed operations: Inherited stacks, duplicated tools, and unclear ownership of orphan machines made operations and governance harder. Rising cost and complexity of on-premises operation: Colocation fees, energy and cooling costs, server refresh cycles, and tooling renewals were difficult to justify against cloud economics. Limited capacity and skills to refactor at scale: Teams wanted the cost and agility benefits of the cloud but didn’t have the time or skills to rewrite hundreds (or thousands) of VMs on aggressive timelines. Security and audit pressure: Disparate environments and legacy access models elevated risk and created audit friction. Operational variability and end-user experience: VPN dependencies, inconsistent remote tooling, and endpoint logistics led to slow first-call resolution and downtime risks. Three quantified benefits that drive the business case 1) Reduction in downtime and associated costs by 80% In the study, interviewees reported that moving VMware workloads to AVS improved day-to-day reliability by eliminating fragile on-premises workflows and leveraging Azure’s managed infrastructure. Examples included fewer VPN-related failures, faster issue resolution through centralized tooling, and stronger service-level performance. For leadership teams, this benefit is about more than avoided cost. Better up time protects customer experience, employee productivity, and reduces the operational noise that can slow modernization programs. 2) Reduced infrastructure costs through data center exit, refresh avoidance, and cleanup A second driver is the ability to avoid or eliminate significant portions of data center cost and refresh spend. In the study, interviewees described using AVS to close data centers, avoid upcoming hardware refresh cycles, and reduce ongoing capital and operating costs. Importantly, interviewees also reported that migration waves prompted additional savings through portfolio hygiene by validating each VM, decommissioning redundant systems, and rightsizing oversized workloads. Those actions helped organizations reduce their ongoing compute, storage, and licensing footprint after migration. 3) Redeployment of 50% of IT team members from maintenance to modernization The TEI study quantifies a practical advantage of a managed VMware environment in Azure: fewer hours spent on hardware lifecycle, cluster patching, upgrades, and other routine data center tasks. In practice, many leaders treat this as capacity created rather than budget eliminated: the opportunity to shift experienced engineers toward modernization, automation, cloud governance, proactive incident prevention, and higher-value business initiatives. Unquantified benefits organizations should weigh Beyond the quantified categories, the study also highlights benefits that are strategically important, but not fully quantified in the model: Acceleration of future modernization: With workloads running in Azure via AVS, organizations can integrate platform services across security, identity, data, and analytics and build a runway for new capabilities, including AI-driven scenarios in Azure. Fast, cost-effective migration of legacy workloads: Interviewees described avoiding major consulting or hiring costs that would have been required to refactor complex workloads into cloud-native designs. Improved audit readiness and security posture: Consolidating fragmented environments into governed Azure landing zones can simplify audit preparation and strengthen governance and monitoring. For many leadership teams, these benefits strengthen the business case because they support broader transformation outcomes that extend beyond infrastructure cost alone. Things to consider in your own decision process If you’re building a business case to move workloads to Azure, whether it be lifting and shifting to AVS or replatforming and refactoring to Azure IaaS and managed services, consider mapping your environment across these areas: Data center timelines: Refresh cycles, colocation exit deadlines, and contract constraints. Operating model readiness: How quickly teams can adopt cloud-native services versus preserving VMware operations during transition. Modernization roadmap: Determine which applications are candidates for investment in replatforming, refactoring, replacement, or retirement once in Azure.

ROI is calculated by dividing net benefits (benefits less costs) by costs. 3 Net present value (NPV): The present or current value of (discounted) future net cash flows given an interest rate (the discount rate). A positive project NPV normally indicates that the investment should be made unless other projects have higher NPVs. 4 Payback: The breakeven point for an investment. This is the point in time at which net benefits (benefits minus costs) equal initial investment or cost.Join us at Microsoft Azure Infra Summit 2026 for deep technical Azure infrastructure content
Microsoft Azure Infra Summit 2026 is a free, engineering-led virtual event created for IT professionals, platform engineers, SREs, and infrastructure teams who want to go deeper on how Azure really works in production. It will take place May 19-21, 2026. This event is built for the people responsible for keeping systems running, making sound architecture decisions, and dealing with the operational realities that show up long after deployment day. Over the past year, one message has come through clearly from the community: infrastructure and operations audiences want more in-depth technical content. They want fewer surface-level overviews and more practical guidance from the engineers and experts who build, run, and support these systems every day. That is exactly what Azure Infra Summit aims to deliver. All content is created AND delivered by engineering, targeting folks working with Azure infrastructure and operating production environments. Who is this for: IT professionals, platform engineers, SREs, and infrastructure teams When: May 19-21, 2026 - 8:00 AM–1:00 PM Pacific Time, all 3 days Where: Online Virtual Cost: Free Level: Most sessions are advanced (L300-400). Register here: https://aka.ms/MAIS-Reg Built for the people who run workloads on Azure Azure Infra Summit is for the people who do more than deploy to Azure. It is for the people who run it. If your day involves uptime, patching, governance, monitoring, reliability, networking, identity, storage, or hybrid infrastructure, this event is for you. Whether you are an IT professional managing enterprise environments, a platform engineer designing landing zones, an Azure administrator, an architect, or an SRE responsible for resilience and operational excellence, you will find content built with your needs in mind. We are intentionally shaping this event around peer-to-peer technical learning. That means engineering-led sessions, practical examples, and candid discussion about architecture, failure modes, operational tradeoffs, and what breaks in production. The promise here is straightforward: less fluff, more infrastructure. What to expect Azure Infra Summit will feature deep technical content in the 300 to 400 level range, with sessions designed by engineering to help you build, operate, and optimize Azure infrastructure more effectively. The event will include a mix of live and pre-recorded sessions and live Q&A. Throughout the three days, we will dig into topics such as: Hybrid operations and management Networking at scale Storage, backup, and disaster recovery Observability, SLOs, and day-2 operations Confidential compute Architecture, automation, governance, and optimization in Azure Core environments And more… The goal is simple: to give you practical guidance you can take back to your environment and apply right away. We want attendees to leave with stronger mental models, a better understanding of how Azure behaves in the real world, and clearer patterns for designing and operating infrastructure with confidence. Why this event matters Infrastructure decisions have a long tail. The choices we make around architecture, operations, governance, and resilience show up later in the form of performance issues, outages, cost, complexity, and recovery challenges. That is why deep technical learning matters, and why events like this matter. Join us I hope you will join us for Microsoft Azure Infra Summit 2026, happening May 19-21, 2026. If you care about how Azure infrastructure behaves in the real world, and you want practical, engineering-led guidance on how to build, operate, and optimize it, this event was built for you.
