Update ID: 571257 Data source: Azure Updates API
Categories: Retirements
Summary:
What was updated
Support for Azure Linux with OS Guard in Azure Kubernetes Service (AKS) will be retired on December 10, 2026.
Key changes or new features
After December 10, 2026, users will no longer be able to create new Azure Linux node pools with OS Guard in AKS. The recommended replacement is Azure Container Linux, which offers enhanced security and performance features. Existing deployments will not be supported after this date.
Target audience affected
This update impacts developers and IT professionals managing AKS clusters using Azure Linux with OS Guard. Teams responsible for container orchestration, platform engineering, and security in AKS environments are directly affected.
Important notes if any
To avoid service disruption, migrate workloads from Azure Linux with OS Guard to Azure Container Linux before December 10, 2026. Review your AKS clusters and update deployment templates and automation scripts accordingly. Early migration is recommended to ensure compatibility and continued support.

Comprehensive Technical Explanation: Retirement of Azure Linux with OS Guard in Azure Kubernetes Service
Background and Purpose of the Update
Microsoft has announced the retirement of support for Azure Linux with OS Guard in Azure Kubernetes Service (AKS), effective December 10, 2026. The purpose of this update is to transition users from the preview feature, Azure Linux with OS Guard, to its successor, Azure Container Linux. This change aligns with Microsoft’s ongoing efforts to streamline and enhance container-optimized operating systems within AKS, ensuring improved performance, security, and supportability.
Specific Features and Detailed Changes
The retirement specifically affects Azure Linux with OS Guard, a preview feature designed to provide enhanced OS-level security within AKS. After December 10, 2026, users will no longer be able to create new Azure Linux node pools with OS Guard enabled in AKS. The recommended replacement is Azure Container Linux, which is positioned as the new container-optimized OS for AKS node pools. Existing Azure Linux with OS Guard node pools will not be able to be created post-retirement, and users are encouraged to migrate workloads to Azure Container Linux.
Technical Mechanisms and Implementation Methods
Azure Linux with OS Guard leverages OS Guard technology to enforce additional security boundaries at the operating system level, protecting container workloads from potential threats. The transition to Azure Container Linux involves updating AKS node pool configurations to use the new OS image. Azure Container Linux is designed to provide a secure, lightweight, and efficient environment for running containers, and it is fully integrated with AKS for seamless orchestration and lifecycle management. Migration typically involves updating node pool definitions and redeploying workloads to the new OS platform.
Use Cases and Application Scenarios
Azure Linux with OS Guard has been used in scenarios requiring enhanced OS-level security for containerized workloads, such as regulated industries (finance, healthcare) or environments with strict compliance requirements. Azure Container Linux will continue to serve these use cases, offering a modern, container-focused OS with improved support and performance. Typical application scenarios include microservices architectures, DevOps pipelines, and production-grade Kubernetes clusters requiring robust security and operational efficiency.
Important Considerations and Limitations
Integration with Related Azure Services
Azure Container Linux is fully integrated with Azure Kubernetes Service, supporting native AKS features such as auto-scaling, managed upgrades, monitoring, and security controls. It also works seamlessly with Azure Container Registry, Azure Monitor, and Azure Security Center, enabling end-to-end container lifecycle management and compliance. Migration to Azure Container Linux ensures continued compatibility with Azure’s ecosystem of container and orchestration services.
Summary Sentence
Support for Azure Linux with OS Guard in Azure Kubernetes Service will end on December 10, 2026, and users are advised to migrate to Azure Container Linux for continued container-optimized OS support in AKS.
Published: September 11, 2026 15:58:56 UTC Link: Public Preview: Agentless migration of on-premises SMB file shares to Azure Files (SMB)
Update ID: 570910 Data source: Azure Updates API
Categories: In preview, Migration, Storage, Azure Storage Mover, Features
Summary:
What was updated
Azure Storage Mover now supports agentless migration of on-premises SMB file shares to Azure Files (SMB), available in public preview.
Key changes or new features
The new agentless migration capability allows users to move file data from Windows Server or NAS SMB shares to Azure Files without the need to deploy, register, or maintain a migration agent. This simplifies the migration process, reduces infrastructure overhead, and minimizes operational complexity. The feature supports large-scale migrations and is integrated with Azure Storage Mover’s management and monitoring tools.
Target audience affected
This update is relevant for IT professionals and developers responsible for data migration, storage management, and cloud adoption projects. Organizations planning to move file-based workloads from on-premises environments to Azure Files will benefit most.
Important notes if any
This feature is currently in public preview and may not be suitable for production workloads. Users should review preview limitations and provide feedback to Microsoft. Agentless migration reduces the need for additional on-premises resources and streamlines migration planning. For more details and to participate in the preview, refer to the official Azure Update: https://azure.microsoft.com/updates?id=570910
