We’re excited to announce the General Availability of Arc gateway for Arc‑enabled Kubernetes. Arc gateway dramatically simplifies the network configuration required to use Azure Arc by consolidating outbound connectivity through a small, predictable set of endpoints. For customers operating behind enterprise proxies or firewalls, this means faster onboarding, fewer change requests, and a smoother path to value with Azure Arc. What’s new: To Arc‑enable a Kubernetes Cluster, customers previously had to allow 18 distinct endpoints. With Arc gateway GA, you can do the same with just 9, a 50% reduction that removes friction for security and networking teams. Why This Matters Organizations with strict outbound controls often spend days, or weeks, coordinating approvals for multiple URLs before they can onboard resources to Azure Arc. By consolidating traffic to a smaller set of destinations, Arc gateway: Accelerates onboarding for Arc‑enabled Kubernetes by cutting down the proxy/firewall approvals needed to get started. Simplifies operations with a consistent, repeatable pattern for routing Arc agent and extension traffic to Azure. How Arc gateway works Arc gateway introduces two components that work together to streamline connectivity: Arc gateway (Azure resource): A single, unique endpoint in your Azure tenant that receives incoming traffic from on‑premises Arc workloads and forwards it to the right Azure services. You configure your enterprise environment to allow this endpoint. Azure Arc Proxy (on every Arc‑enabled Kubernetes Cluster): A component of the Arc K8s agent that routes agent and extension traffic to Azure via the Arc gateway endpoint. It’s part of the core Arc agent; no separate install is required. At a high level, traffic flows: Arc-enabled Kubernetes agent → Arc Proxy → Enterprise Proxy → Arc gateway → Target Azure service. Scenario Coverage As part of this GA release, Arc-enabled Kubernetes Onboarding and other common Arc‑enabled Kubernetes scenarios are supported through Arc gateway, including: Arc-enabled Kubernetes Cluster Connect Arc-enabled Kubernetes Resource View Custom Location Azure Policy's Extension for Azure Arc For other scenarios, including Microsoft Defender for Containers, Azure Key Vault, Container Insights in Azure Monitor, etc., some customer‑specific data plane destinations (e.g., your Log Analytics workspaces, Storage Accounts, or Key Vault URLs) still need to be allow‑listed per your environment. Please consult the Arc gateway documentation for the current scenario‑by‑scenario coverage and any remaining per‑service URLs. Get started Create an Arc gateway resource using the Azure portal, Azure CLI, or PowerShell. Allow the Arc gateway endpoint (and the small set of core endpoints) in your enterprise proxy/firewall. Onboard or update clusters to use your Arc gateway resource. For step‑by‑step guidance, see the Arc gateway documentation on Microsoft Learn. FAQs Does Arc gateway require new software on my clusters? No additional installation - Arc Proxy is part of the standard Arc-enabled Kubernetes Agent. Will every Arc scenario route through the gateway today? Arc-enablement, and other scenarios are covered at GA; some customer‑specific data plane endpoints (for example, Log Analytics workspace FQDNs) may still need to be allowed. Check the docs for the latest coverage details. What is the status of Arc gateway for other infrastructure types? Arc gateway is already GA for Arc-enabled Servers, and Azure Local. Tell us what you think We’d love your feedback on Arc gateway GA for Kubernetes - what worked well, what could be improved, and which scenarios you want next. Use the Arc gateway feedback form to share your input with the product team.AKS enabled by Azure Arc: Powering AI Applications from Cloud to Edge [Ignite 2025]

We look forward to continuing to support customers as they build the next generation of hybrid and edge AI applications.Workload Identity support for Azure Arc-enabled Kubernetes clusters now Generally Available!
We’re excited to announce that Workload Identity support for Azure Arc-enabled Kubernetes is now Generally Available (GA)! This milestone brings a secure way for applications running on Arc-connected clusters running outside of Azure to authenticate to Azure services without managing secrets. Traditionally, workloads outside Azure relied on static credentials or certificates to access Azure resources like Event Hubs, Azure Key Vault, and Azure Storage. Managing these secrets introduces operational overhead and security risks. With Microsoft Entra Workload ID federation, your Kubernetes workloads can now: Authenticate securely using OpenID Connect (OIDC) without storing secrets. Exchange trusted tokens for Azure access tokens to interact with services securely. This means no more manual secret rotation and reduced attack surface, all while maintaining compliance and governance. How It Works The integration uses Service Account Token Volume Projection and aligns with Kubernetes best practices for identity federation. The process involves a few concise steps: Enable OIDC issuer and workload identity on your Arc-enabled cluster using Azure CLI. az connectedk8s connect --name "${CLUSTER_NAME}" --resource-group "${RESOURCE_GROUP}" --enable-oidc-issuer –-enable-workload-identity Configure a user-assigned managed identity in Azure to trust tokens from your Azure Arc enabled Kubernetes cluster's OIDC issuer URL. This involves creating a federated identity credential that links the Azure identity with the Kubernetes service account. Applications running in pods, using the annotated Kubernetes service account, can then request Azure tokens via Microsoft Entra ID and access resources they’re authorized for (e.g., Azure Storage, Azure Key Vault). This integration uses Kubernetes-native construct of Service Account Token Volume Projection and aligns with Kubernetes best practices for identity federation. Supported platforms We support a broad ecosystem of distributions, including: Red Hat OpenShift Rancher K3s AKS-Arc (In preview) VMware Tanzu Kubernetes Grid (TKGm) So, whether you’re running clusters in retail stores, manufacturing plants, or remote edge sites, you can connect them to Azure Arc and enable secure identity federation for your workloads to access Azure services. Ready to get started?

Together, we pilot compliance assistant agentic workflow with OCR & LLM integration. Villa Park: A Blueprint for Smart Cities The City of Villa Park, California, faced challenges common to many municipalities: complex zoning regulations that slowed approvals, lengthy CEQA compliance processes requiring deep environmental analysis, backlogs in accessory dwelling unit (ADU) permit reviews. Working with DataON, a Microsoft partner, and Microsoft, Villa Park deployed Edge RAG on Azure Local, creating a resilient, intelligent planning system that operates seamlessly; even offline. Environmental assessments that once required days are now completed in minutes. The partnership between the City of Villa Park and DataON is a standout example of how municipalities and technology providers can co-innovate to solve real-world challenges. Ray Pascua, Villa Park’s Planning Manager, has led this transformation: “Having the opportunity to utilize AI to perform research and retrieve large datasets specifically from the California Environmental Quality Act (CEQA) Guidelines (Statutory/Categorical Exemptions), and State law relative to Accessory Dwelling Units (ADUs), has been an overall positive experience. AI algorithm is a revolutionary medium that can streamline and improve workflow efficiencies by automating routine and repetitive planning-related tasks and analysis, and would be of particular value and benefit to local government agencies that have limited personnel and resources. While this cutting-edge technological tool is still evolving and has room to improve accuracy and speed, it certainly has a place in the realm of City Planning, as well as other land use development fields and disciplines.” Howard Lo, VP of Sales & Marketing at DataON, shares: “Our collaboration with Microsoft and the City of Villa Park showcases Azure Local's transformative potential for municipal government AI. As a leading Azure Local partner, DataON has optimized our infrastructure to run Microsoft's Edge RAG solution, enabling Villa Park to address real planning challenges while maintaining data control and security. Working directly with Microsoft's engineering team and a forward-thinking city partner, we've proven that Azure Local delivers practical AI value for government operations.

DataON provides robust hardware and delivers deployment, integration, and training services, ensuring a seamless Azure Local experience. Their close support helps organizations quickly adopt and confidently manage edge solutions, resulting in secure, high-performance, and scalable deployments for multi-site environments. Let’s take a closer look at the features we’re announcing today: Deep Search for Complex Reasoning with LazyGarph RAG With the Ignite release, Edge RAG introduces Deep Search powered by LazyGraph RAG; a dynamic graph-based retrieval method that enables advanced, multi-document reasoning. This means Villa Park planners can now ask complex, multi-part questions that span zoning, CEQA, and ADU regulations, and Edge RAG will synthesize answers by connecting information from multiple sources in real time. Image 1: Deep Search capabilities on Edge RAG The system incrementally explores only the most relevant document chunks, reducing compute cost and latency while delivering comprehensive, cited responses. For Villa Park, this translates to resolving intricate regulatory scenarios, such as “What are the environmental constraints for ADUs in zones X, Y, and Z?”. With answers that reference and link multiple regulatory documents and historical decisions, all in a single query. Advanced Document Parsing for Structured Data Edge RAG’s advanced document parsing, introduced in this release, transforms how Villa Park’s planning documents are utilized. During data ingestion, the system now extracts not only free-form text but also tables, images, headings, and rich metadata. This includes full indexing of multi-page tables, column headers, and section context, with each chunk annotated by page number, section heading, and table index. As a result, planners can search for specific permit statistics, environmental impact scores, or compliance tables and retrieve results directly from structured data within city documents; enabling precise, source-attributed answers that were previously difficult or impossible to obtain. Image 2: Advanced document parsing on Edge RAG Enhanced Chat Experience The new model-only chat mode allows staff to interact directly with the language model, bypassing contextual data for general queries or troubleshooting. This flexibility enables Villa Park staff to quickly switch between knowledge-based chat-grounded in city data, and model-only chat for training, testing, or handling ambiguous queries, streamlining both day-to-day operations and onboarding of new team members. Additional Edge RAG Preview Refresh Updates We also improved Edge RAG based on customer feedback, adding these features: Agentic RAG for autonomous workflows: Systems can reason and act at the edge with less manual work. Full offline support: Operates and accesses data even without a network. SharePoint integration (private preview): users will also be able to query Edge RAG directly over SharePoint, enabling enhanced information retrieval and analysis within their workflows. Image 3: Sharepoint as a data source on Edge RAG Performance optimizations: Query responses for every search type, excluding Deep Search, are now delivered in under 15 seconds on legacy A2 and A16 GPUs; a fivefold speed boost. Additionally, streaming image processing has increased one hundred times, allowing 600 images to be handled continuously in just 36 seconds. Since late May, Edge RAG has supported “bring your own model” (BYOM), allowing organizations to deploy their preferred language models such as OpenAI GPT-4o or other advanced models, directly on their own infrastructure. This capability enables advanced features like deep search and hybrid multimodal search, while ensuring that sensitive data remains on-premises. BYOM empowers organizations to tailor Edge RAG’s AI capabilities to their unique compliance, performance, or customization requirements, maintaining full control over both data and model selection. Security, Compliance, and Sustainability Edge RAG is built for trust: data sovereignty ensures sensitive data remains on-premises, zero-trust architecture integrates with Microsoft security stack, and compliance-ready design supports municipal, state, and industry regulations. Sustainability is also a priority, with energy-efficient edge hardware reducing carbon footprint. Looking Ahead: The Future of Edge Intelligence Edge RAG enables flexible edge intelligence deployment in various environments.

Announcing General Availability of the Azure Key Vault Secret Store Extension
We are thrilled to announce Azure Key Vault Secret Store Extension (SSE) is now generally available for Arc-enabled on-premises Kubernetes, including clusters that you connect yourself and AKS Arc managed clusters. SSE automatically fetches secrets from an Azure Key Vault to the on-premises cluster for offline access. This means you can use Azure Key Vault to store, maintain, and rotate your secrets, even when running your Kubernetes cluster in a semi-disconnected state. Key Benefits Offline Access: It’s important that workloads continue even when there are temporary disruptions to connectivity. This includes regular operation as well as the ability to restart pods while there’s a connectivity interruption. With SSE, workloads can access secrets from the local Kubernetes secrets store regardless of connectivity interruptions. Standard K8s Secret Access: Secrets can be accessed via volume mounting, environment variables, or via the Kubernetes API. Workloads and ingress controllers do not need to be customized to access Azure Key Vault and developers have options on how to access secrets. Security: SSE has limited permissions and leverages the latest Kubernetes security features so that cluster admins do not need to configure and limit permissions themselves. Secrets are critical business assets, so the Secret Store helps to secure them through isolated namespaces, role-based access control (RBAC) policies, federated identities for accessing AKV, and limited permissions for the secrets synchronizer. Scalability: SSE helps very large distributed deployments with hundreds or thousands of clusters to work with Azure Key Vault by spreading demand over time. By effectively caching secrets in the Kubernetes secrets store, SSE can also help to lower overall demand on Azure Key Vault instances. Low maintenance: Auto-updates can keep your SSE up to date with security and performance improvements as they are released. Additionally, changes to configured secrets are even easier now with the new simplified configuration experience (in preview). With the simplified configuration style, a single custom resource is all that’s needed, reducing the effort and surface area for misconfigurations. How to Use the Secret Store Extension Install the Secret Store Extension to an Arc-enabled cluster or AKS managed on-premises cluster with configuration parameters such as sync intervals. Configure an Azure managed identity that has permission to read secrets from AKV and federate it with a Kubernetes service account. Configure a secret provider class custom resource (CR) in the cluster with connection details to the Key Vault. Configure a secret sync custom resource (CR) in the cluster for each secret to be synchronized. (Steps 3 and 4 are now even easier with the new simplified configuration!) Apply the CRs in the cluster and secrets will automatically begin syncing to the cluster. Relax knowing that your configured secrets will be kept up to date on the cluster, as frequently as you want.
