1. Retirement: Confidential VM SKUs DCesv5, DCedsv5, ECesv5, ECedsv5 SKUs

Published: September 02, 2025 18:45:30 UTC Link: Retirement: Confidential VM SKUs DCesv5, DCedsv5, ECesv5, ECedsv5 SKUs

Update ID: 502039 Data source: Azure Updates API

Categories: Compute, Virtual Machines, Retirements, Services

Summary:

Details:

Microsoft has announced the retirement of the Confidential VM SKUs DCesv5, DCedsv5, ECesv5, and ECedsv5, which will be replaced by the next-generation Confidential VM SKUs DCesv6 and ECesv6. This update reflects Microsoft’s ongoing effort to enhance confidential computing capabilities on Azure by providing improved security, performance, and compliance features in virtual machines designed to protect sensitive data in use.

Background and Purpose of the Update
Confidential VMs on Azure leverage hardware-based Trusted Execution Environments (TEEs), such as Intel SGX or AMD SEV, to ensure data confidentiality and integrity while it is processed in memory. The DCesv5 and ECesv5 series were among the earlier Confidential VM SKUs that enabled customers to run sensitive workloads with enhanced security guarantees. However, as confidential computing technology evolves, Microsoft is retiring these older SKUs to focus on the newer DCesv6 and ECesv6 SKUs, which incorporate advancements in hardware and software security, better performance, and expanded capabilities. This transition encourages customers to migrate to the latest VM sizes to benefit from improved security assurances and operational efficiencies.

Specific Features and Detailed Changes

Technical Mechanisms and Implementation Methods
Confidential VMs use hardware-based TEEs to create isolated execution environments within the CPU, preventing unauthorized access to data even from privileged system software or cloud administrators. The v6 SKUs leverage the latest generation of these TEEs, such as AMD SEV-SNP or Intel TDX, which provide stronger guarantees against attacks like memory snooping, replay attacks, and privilege escalation. Migration to the new SKUs involves redeploying workloads on the updated VM sizes and ensuring compatibility with the updated confidential computing SDKs and attestation services. Azure’s attestation services continue to provide cryptographic proof of the VM’s trusted state, enabling secure key provisioning and workload authentication.

2. Retirement: Azure CDN – Migrate to Azure Front Door on December 1, 2025

Published: September 02, 2025 18:00:44 UTC Link: Retirement: Azure CDN – Migrate to Azure Front Door on December 1, 2025

Update ID: 501174 Data source: Azure Updates API

Categories: Networking, Security, Azure Front Door, Retirements

Summary:

Reference: https://azure.microsoft.com/updates?id=501174

Details:

The announced retirement of Azure CDN operated by 21Vianet in China, effective December 1, 2025, mandates that all customers currently using Azure CDN within the China region transition to Azure Front Door, reflecting Microsoft’s strategic consolidation of its global content delivery and application acceleration services.

Background and Purpose:
Azure CDN in China, delivered through partnerships with local CDN providers under 21Vianet’s operation, has served as a content delivery solution optimized for the Chinese market. The retirement aligns with Microsoft’s effort to unify its edge and application delivery capabilities under Azure Front Door, which offers enhanced performance, security, and global scalability. This migration aims to provide customers with a more integrated, feature-rich platform that simplifies management and improves user experience.

Specific Features and Detailed Changes:
Azure Front Door is a modern, scalable, and secure application delivery network that combines global load balancing, SSL offloading, web application firewall (WAF), and application acceleration. Unlike Azure CDN, which primarily focuses on static content caching, Azure Front Door supports dynamic site acceleration, SSL termination, URL-based routing, session affinity, and enhanced security features. The retirement means that customers will no longer be able to provision or manage Azure CDN endpoints in China after the cutoff date and must migrate existing workloads to Azure Front Door to maintain content delivery and application acceleration services.

Technical Mechanisms and Implementation Methods:
Migration involves reconfiguring endpoints and routing rules from Azure CDN to Azure Front Door. Azure Front Door uses Anycast IP addresses and a global network of edge POPs, including those in China operated by 21Vianet, to deliver low-latency content and route traffic intelligently. Customers will need to recreate CDN endpoint configurations as Front Door frontend hosts and backend pools, define routing rules, and configure WAF policies if applicable. DNS updates will be necessary to point to the new Front Door endpoints. Azure Front Door supports integration with Azure Traffic Manager and Azure Application Gateway for hybrid routing and advanced security scenarios.

Use Cases and Application Scenarios:
Azure Front Door is suitable for scenarios requiring global load balancing, secure application delivery, and dynamic content acceleration. Typical use cases include e-commerce platforms, media streaming, SaaS applications, and APIs that demand high availability and low latency. Customers currently leveraging Azure CDN for static content caching in China will benefit from Front Door’s additional capabilities such as SSL offloading and WAF protection, enhancing both performance and security.

Important Considerations and Limitations:

Integration with Related Azure Services:
Azure Front Door integrates natively with Azure Monitor for telemetry, Azure Security Center for threat detection, and Azure Active Directory for access control. It can be combined with Azure Web Application Firewall for enhanced security and Azure Traffic Manager for DNS-based traffic routing. Additionally, Azure Front Door supports integration with Azure DevOps and Infrastructure as Code (IaC) tools for automated deployment and management.

In summary, the retirement of Azure CDN in China operated by 21Vianet requires customers to migrate to Azure Front Door by December 1, 2025, to leverage a unified, secure, and scalable application delivery platform that enhances performance and security while aligning with Microsoft’s global Azure networking strategy.


3. Generally Available: Playwright Workspaces in Azure App Testing

Published: September 02, 2025 17:00:13 UTC Link: Generally Available: Playwright Workspaces in Azure App Testing

Update ID: 501953 Data source: Azure Updates API

Categories: Launched, Developer tools, DevOps, Azure Load Testing, Features

Summary:

Details:

The recent general availability of Playwright Workspaces in Azure App Testing introduces a robust capability designed to enhance automated end-to-end testing by enabling high parallelization of test executions across multiple browsers and devices. This update addresses the growing need for scalable, cross-platform functional validation in modern application development and deployment pipelines.

Background and Purpose
As applications increasingly target diverse environments—ranging from desktop browsers to mobile devices—ensuring consistent functionality across these platforms is critical. Playwright, an open-source testing framework from Microsoft, supports automated testing for Chromium, Firefox, and WebKit browsers. Integrating Playwright Workspaces into Azure App Testing provides a managed, cloud-based environment that simplifies running large-scale, parallelized Playwright tests. The purpose is to accelerate test execution, improve coverage, and reduce the complexity of managing test infrastructure.

Specific Features and Detailed Changes

Technical Mechanisms and Implementation Methods
Playwright Workspaces leverage containerized test agents orchestrated by Azure App Testing’s backend services. When a test run is initiated, the system dynamically allocates resources to spin up isolated environments configured with the required browser engines and device emulators. Tests written in Playwright scripts are dispatched to these environments, executed in parallel, and results aggregated centrally. The platform supports test artifacts collection, including logs, screenshots, and videos, facilitating detailed analysis. Authentication and access control are managed via Azure Active Directory, ensuring secure and compliant operations.
