Patches are available for 2016, 2019, and SE, but not for 2010 or 2013. Organizations should immediately apply updates, restrict access to unsupported versions, and implement custom Azure Web Application Firewall (WAF) rules to detect and block attack patterns targeting vulnerable SharePoint endpoints, as detailed in Microsoft’s official guidance. Azure CNI Overlay for Application Gateway for Containers and Application Gateway Ingress Controller Team Blog: Azure Networking Author: jonw Published: 08/29/2025 Summary: Microsoft has announced the general availability of Azure CNI Overlay for Application Gateway for Containers and AGIC. This integration enhances IP scalability and performance for AKS clusters by enabling direct pod-to-pod routing without encapsulation overhead. It addresses key challenges like IP exhaustion and load balancing for containerized applications. The solution supports over 1 million IPs across clusters in the same VNet and ensures feature parity with kubenet, which is being retired. Customers can now upgrade AKS networking to Azure CNI Overlay while maintaining business continuity and leveraging a high-performance ingress solution. Announcing more Azure VMware Solution enhancements Team Blog: Azure Migration and Modernization Author: christopheherrbach Published: 08/25/2025 Summary: Microsoft announced several enhancements to Azure VMware Solution (AVS) at VMware Explore in Las Vegas, including expansion to 35 global regions with eight more planned by year-end. AVS now offers improved support for VMware Cloud Foundation, DISA IL5 authorization for government use, flexible Azure NetApp Files storage options, and expanded Azure Elastic SAN support for all node types. These updates make AVS a robust choice for migrating and optimizing VMware workloads in Azure, with resources available for learning and skill-building through the Azure VMware Solution 2025 Learn Challenge. Container Networking with Azure Application Gateway for Containers (AGC): Overlay vs. Flat AKS Team Blog: Azure Infrastructure Author: lakshaymalik Published: 08/31/2025 Summary: Azure Application Gateway for Containers (AGC) integrates with AKS using two networking models: Overlay (Azure CNI Overlay) and Flat (Azure CNI Pod/Node Subnet). Overlay conserves VNet IPs by assigning pods overlay CIDRs, while Flat gives pods VNet-routable IPs for direct access. AGC auto-detects the model, requires a /24 subnet, supports network policies, and leverages Layer-7 routing and security features. Deployment uses Gateway API resources without changes for either model. Overlay requires ALB Controller v1.7.9+. AGC enables flexible, secure, and scalable ingress for AKS, integrating with Azure’s security and monitoring tools. Designing for Certainty: How Azure Capacity Reservations Safeguard Mission‑Critical Workloads Team Blog: Azure Governance and Management Author: Goutham_Bandapati Published: 08/25/2025 Summary: Azure Capacity Reservations allow organizations to secure specific VM resources in designated regions or zones, ensuring availability for mission-critical workloads during demand spikes. Unlike Reserved Instances, which offer cost savings for steady usage but don’t guarantee resource access, Capacity Reservations guarantee placement but incur costs even if idle. Combining both approaches—reserving capacity for reliability and using Reserved Instances for savings—mitigates risk, optimizes costs, and enhances resilience against unpredictable cloud demand, especially for regulated, latency-sensitive, or high-stakes workloads. This strategy is essential across all major clouds to transform capacity from a risk into a managed asset. Upcoming Changes to Instance Size Flexibility Ratios for Azure Reservations: What You Need to Know Team Blog: Azure Compute Author: kyleikeda Published: 08/04/2025 Summary: On September 4, Azure will update instance size flexibility ratios for reservations covering select Virtual Machines, Azure Redis Cache, and Dedicated Hosts. These changes, aimed at optimizing reservation discounts, may impact reservation coverage—potentially increasing or decreasing the number of units covered—without changing prices. Users should review impacted SKUs and monitor reservation utilization after the update to manage costs effectively. Recommendations include adjusting usage, exchanging reservations, or utilizing Azure Advisor for cost-saving strategies. Guidance is available in the Azure Portal and Microsoft documentation. SQL Server enabled by Azure Arc is now generally available in the US Government Virginia region Team Blog: Azure Arc Author: AbdullahMSFT Published: 08/14/2025 Summary: SQL Server enabled by Azure Arc is now generally available in the US Government Virginia region, allowing government agencies to manage on-premises SQL Server instances through the Azure Government portal securely and compliantly. Key features include onboarding SQL Server instances, inventory management, extended security updates, and licensing management. Some advanced features, like failover clustering and certain services, were initially unavailable but have since been enabled, including Always On availability groups and SQL Server services. This launch marks a significant step for hybrid data management in the government cloud, with further enhancements planned. Mobile Plans moves to the web Team Blog: Windows OS Platform Author: HunterM Published: 08/28/2025 Summary: Microsoft is retiring the Windows Mobile Plans app to simplify mobile data activation on PCs. Users will now buy and manage cellular plans directly through mobile operator websites and Windows Settings, eliminating the need for a separate app. eSIM activation will be streamlined and secure, with device IDs shared via Windows Settings. The transition begins in the second half of 2025, with full retirement by February 2026. Existing cellular functions remain unaffected. Operators gain more control over the activation process, and Microsoft is supporting them through the transition for a seamless user experience.
