Announcing the General Availability of the Azure Arc Gateway for Arc-enabled Servers!
We’re excited to announce the General Availability of Arc gateway for Arc‑enabled servers. 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 server, customers previously had to allow 19 distinct endpoints. With Arc gateway GA, you can do the same with just 7, a ~63% 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 servers 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 server): A component of the connected machine 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 agent → Arc Proxy → Enterprise Proxy → Arc gateway → Target Azure service. Scenario Coverage As part of this GA release, common Arc‑enabled Server scenarios are supported through the gateway, including: Windows Admin Center SSH Extended Security Updates (ESU) Azure Extension for SQL Server For other scenarios, some customer‑specific data plane destinations (e.g., your Log Analytics workspace or Key Vault URLs) may 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. Over time, the number of scenarios filly covered by Arc gateway will continue to grow. 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 servers to use your Arc gateway resource and start managing them with Azure Arc. For step‑by‑step guidance, see the Arc gateway documentation on Microsoft Learn. You can also watch a quick Arc gateway Jumpstart demo to see the experience end‑to‑end. FAQs Does Arc gateway require new software on my servers? No additional installation - Arc Proxy is part of the standard connected machine agent for Arc‑enabled servers. Will every Arc scenario route through the gateway today? Many high‑value server 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. When will Arc gateway for Azure Local be GA? Today! Please refer to the Arc gateway GA on Azure Local Announcement to learn more. When will Arc gateway for Arc-enabled Kubernetes be GA? We don't have an exact ETA to share quite yet for Arc gateway GA for Arc-enabled Kubernetes. The feature is currently still in Public Preview. Please refer to the Public Preview documentation for more information. Tell us what you think We’d love your feedback on Arc gateway GA for servers—what worked well, what could be improved, and which scenarios you want next.

Hello everyone, Now that the Azure Arc gateway is GA is announced, we are super happy to also announce the General Availability of the Arc Gateway for Azure Local! This launch represents a major leap forward in how organizations can securely and efficiently connect their on-premises and edge environments to Azure. Arc Gateway revolutionizes Azure Local connectivity to Azure If you’ve ever tried to connect on-premises resources to Azure, you know the challenges: dozens (sometimes hundreds!) of outbound firewall rules, complex configurations, and ongoing security concerns. It’s a lot to manage, and frankly, it’s not the experience we want for our customers or partners. Arc Gateway changes the game. With a single, centralized HTTPS egress point for all Azure-bound traffic from your Azure Local instances and workloads, you dramatically reduce complexity and risk. Instead of managing countless endpoints, you only need to allow a small, well-defined set—making your environment more secure and much easier to operate. What Makes Arc Gateway for Azure Local to Stand Out? Let me highlight what makes Arc Gateway stand out: Unified and secure Azure Traffic Management: All HTTPS traffic from your Azure Local instances flows through one front door—the Arc Gateway. No more sprawling firewall rules or wildcards. Significantly Fewer Endpoints: We’ve reduced the number of required endpoints from over 100 to fewer than 28. This means less guess work and a much simpler security posture. Comprehensive Integration for your workloads: Arc Gateway isn’t just for infrastructure endpoints. It also fully supports Azure Local VMs with Arc gateway, and AKS clusters in preview mode, streamlining connectivity across your entire hybrid estate. Seamless Enterprise Proxy Integration: Already using an enterprise proxy? Arc Gateway fits right in, routing outbound traffic through your existing proxy before heading to Azure. For a deeper technical dive, I encourage you to check out our detailed article: Azure Local – Arc gateway outbound connectivity deep dive FAQs: Is it possible to enable Arc gateway on my existing Azure local clusters? We are working hard to enable this feature in a future release of Azure Local. Can I enable Arc gateway on my existing Azure Local VMs if it was not enabled for the infrastructure during deployment? Using Arc gateway for your Azure Local VMs is possible regardless of the infrastructure. If you have a working Arc gateway resource you can deploy new Azure Local VMs or attach existing Azure Local VMs if guest management is enabled. Can I enable Arc gateway on my existing Azure Local AKS Clusters? If you enabled Arc gateway during deployment for the Azure Local infrastructure, AKS Clusters will implicitly leverage the Arc gateway running on the hosts. AKS Clusters running in Azure Local with Arc gateway will remain in Public Preview until GA is released in the future.

Today, we’re sharing more details about the end of support for Azure Local, with OS version 25398.xxxx (23H2) on October 31, 2025. After this date, monthly security and quality updates stop, and Microsoft Support remains available only for upgrade assistance. Your billing continues, and your systems keep working, including registration and repair. There are several options to upgrade to Azure Local, with OS version 26100.xxxx (24H2) depending on which scenario applies to you. Scenario #1: You are on Azure Local solution, with OS version 25398.xxxx If you're already running the Azure Local solution, with OS version 25398.xxxx, there is no action required. You will automatically receive the upgrade to OS version 26100.xxxx via a solution update to 2509. Azure Local, version 23H2 and 24H2 release information - Azure Local | Microsoft Learn for the latest version of the diagram. If you are interested in upgrading to OS version 26100.xxxx before the 2509 release, there will be an opt-in process available in the future with production support. Scenario #2: You are on Azure Stack HCI and haven’t performed the solution upgrade yet Scenario #2a: You are still on Azure Stack HCI, version 22H2 With the 2505 release, a direct upgrade path from version 22H2 OS (20349.xxxx) to 24H2 OS (26100.xxxx) has been made available.

Big news for Azure Local customers! Starting in Azure Local version 2506, we’re excited to announce the Public Preview of Software Defined Networking (SDN) on Azure Local using the Azure Arc resource bridge. This release introduces cloud-native networking capabilities for access control at the network layer, utilizing Network Security Groups (NSGs) on Azure Local. Key highlights in this release are: 1- Centralized network management: Manage Logical networks, network interfaces, and NSGs through the Azure control plane – whether your preference is the Azure Portal, Azure Command-Line Interface (CLI), or Azure Resource Manager templates. 2- Fine-grained traffic control: Safeguard your edge workloads with policy-driven access controls by applying inbound and outbound allow/deny rules on NSGs, just as you would in Azure. 3- Seamless hybrid consistency: Reduce operational friction and accelerate your IT staff’s ramp-up on advanced networking skills by using the same familiar tools and constructs across both Azure public cloud and Azure Local. Software Defined Networking (SDN) forms the backbone of delivering Azure-style networking on-premises. Whether you’re securing enterprise applications or extending cloud-scale agility to your on-premises infrastructure, Azure Local, combined with SDN enabled by Azure Arc, offers a unified and scalable solution. Try this feature today and let us know how it transforms your networking operations! What’s New in this Preview? Here’s what you can do today with SDN enabled by Azure Arc: ✅ Run SDN Network Controller as a Failover Cluster service — no VMs required! ✅ Deploy logical networks — use VLAN-backed networks in your datacenter that integrate with SDN enabled by Azure Arc. ✅ Attach VM Network Interfaces — assign static or DHCP IPs to VMs from logical networks. ✅ Apply NSGs - create, attach, and manage NSGs directly from Azure on your logical networks (VLANs in your datacenter) and/or on the VM network interface. This enables a generic rule set for VLANs, with a crisper rule set for individual Azure Local VM network interface using a complete 5-tuple control: source and destination IP, port, and protocol. ✅ Use Default Network Policies — apply baseline security policies during VM creation for your primary NIC. Select well-known inbound ports such as HTTP (while we block everything else for you), while still allowing outbound traffic. Or select an existing NSG you already have! SDN enabled by Azure Arc (Preview) vs. SDN managed by on-premises tools Choosing Your Path: Some SDN features like virtual networks (vNETs), Load Balancers (SLBs), and Gateways are not yet supported in the SDN enabled by Azure Arc (Preview). But good news: you’ve still got options. If your workloads need those features today, you can leverage SDN managed by on-premises tools: - SDN Express (PowerShell) - Windows Admin Center (WAC) The SDN managed by on-premises tools continues to provide full-stack SDN capabilities, including SLBs, Gateways, and VNET peering, while we actively work on bringing this additional value to complete SDN enabled by Azure Arc feature set. You must choose one of the modes of SDN management and cannot run in a hybrid management mode, mixing the two. Please read this important consideration section before getting started! Thank You to Our Community This milestone was only possible because of your input, your use cases, and your edge innovation. We're beyond excited to see what you build next with SDN enabled by Azure Arc. To try it out, head to the Azure Local documentation Let’s keep pushing the edge forward. Together!
EOL of Azure Linux 2.0 on Azure Kubernetes Service enabled by Azure Arc
