Details:

The Azure App Service Premium v4 tier, now generally available, introduces a significant upgrade to the existing Premium plans by leveraging the latest Azure infrastructure to deliver enhanced compute performance, faster local storage, and improved memory configurations for both Windows and Linux web applications. This update addresses the growing demand for higher-performing, scalable, and cost-efficient app hosting environments suitable for enterprise-grade workloads.

Background and Purpose
Azure App Service is a fully managed platform for building, deploying, and scaling web apps. The Premium tiers have traditionally catered to production workloads requiring better performance, scaling, and advanced networking features. With evolving application demands—such as higher throughput, lower latency, and memory-intensive processing—Microsoft has introduced the Premium v4 offering to provide customers with improved hardware capabilities and optimized resource allocation. This update aims to enhance application responsiveness and scalability while maintaining the platform’s ease of use and integration capabilities.

Specific Features and Detailed Changes

• Faster Processors: Premium v4 uses the latest generation of Azure CPUs, resulting in higher clock speeds and improved single-thread and multi-thread performance. This translates to faster request processing and better handling of concurrent workloads.
• NVMe Local Storage: Unlike previous tiers that used standard SSDs, Premium v4 incorporates NVMe-based local storage, offering significantly lower latency and higher IOPS for temporary storage needs such as caching, session state, or temporary files. This is especially beneficial for apps with heavy I/O operations.
• Memory-Optimized Options: The new tier introduces memory-optimized sizes, allowing applications that require large in-memory caches or data processing to benefit from increased RAM availability.
• Platform Support: Premium v4 is available for both Windows and Linux app service plans, ensuring broad applicability across diverse application stacks.
• Instance Sizes: The offering starts from 1 vCPU and 4 GB RAM, scaling up to larger sizes, providing flexibility to right-size the environment based on workload requirements.

Technical Mechanisms and Implementation Methods
Premium v4 plans run on upgraded Azure hardware clusters featuring the latest Intel or AMD processors with enhanced virtualization optimizations. The NVMe local storage is directly attached to the host VM, providing ultra-fast ephemeral storage accessible to the app sandbox. Memory-optimized SKUs allocate higher RAM per vCPU ratio, achieved through updated VM SKUs underlying the App Service infrastructure. Customers can upgrade existing Premium v3 plans to Premium v4 via the Azure Portal or CLI with minimal downtime, as the platform orchestrates the migration to new hardware transparently.

Use Cases and Application Scenarios

• High-Performance Web Applications: Apps requiring faster CPU processing for complex logic or high request volumes benefit from the improved processors.
• In-Memory Caching and Data Processing: Applications that rely on large caches or in-memory databases gain from memory-optimized SKUs.
• I/O-Intensive Applications: NVMe local storage accelerates workloads involving temporary file storage, session state, or caching layers.
• Enterprise Applications: Businesses needing robust, scalable, and secure app hosting with advanced networking and compliance features can leverage Premium v4 for production workloads.
• Linux and Windows Apps: Diverse app stacks, including .NET, Node.js, Java, Python, and PHP, can utilize the new tier equally.

Important Considerations and Limitations

• Ephemeral Storage: NVMe local storage is temporary and not persistent; data stored locally can be lost during app restarts or scaling operations. Critical data should be stored in durable Azure storage services.
• Cost Implications: Premium v4 plans may have higher pricing due to upgraded hardware; careful sizing and scaling strategies are recommended to optimize costs.
• Compatibility: While most apps will run seamlessly, some legacy or specialized workloads may require testing to ensure compatibility with the new hardware and OS versions.
• Scaling: Premium v4 supports both vertical scaling (changing instance size) and horizontal scaling

2. Generally Available: Azure Front Door Standard and Premium are now available in Azure China.

Published: September 01, 2025 10:00:54 UTC Link: Generally Available: Azure Front Door Standard and Premium are now available in Azure China.

Update ID: 501200 Data source: Azure Updates API

Categories: Launched, Networking, Security, Azure Front Door, Services, Regions & Datacenters, Pricing & Offerings

Summary:

• What was updated
  Azure Front Door Standard and Premium SKUs are now generally available in Azure China regions (China North 3 and China East 3), operated by 21Vianet.

• Key changes or new features
  This release enables customers in China to leverage Azure Front Door’s global edge network for secure, reliable, and high-performance application delivery. Both Standard and Premium tiers offer enhanced web application acceleration, global load balancing, SSL offloading, and advanced security features such as Web Application Firewall (WAF). The Premium SKU additionally provides advanced capabilities like private link integration, enhanced routing, and bot protection.

• Target audience affected
  Developers and IT professionals managing cloud applications and infrastructure in China who require global-scale, secure, and performant application delivery solutions.

• Important notes if any
  Availability in China regions means compliance with local regulations and data residency requirements, operated by 21Vianet.
