AppFabric Caching’s
Final End-of-Life Is Here

  • Easily migrate to ScaleOut StateServer®
  • ScaleOut offers comprehensive resources and support
  • Includes complete AppFabric Caching Compatibility Library

Microsoft discontinued all Windows Server AppFabric (WSAF) Caching support on April 12, 2022.

ScaleOut StateServer® gives you a better option. It’s deployable either on your existing on-premise environment or in the cloud and is much easier to install and manage. Its advanced features go far beyond most distributed caching solutions:

  • Automatic scaling and integrated high availability
  • No need to manage a centralized configuration store
  • Fully peer-to-peer architecture for maximum scalability
  • Powerful, intuitive GUI management tools
  • Distributed, parallel LINQ query
  • In-memory computing for advanced queries
  • Multi-datacenter replication and access

You have two choices for approaching your migration:

  1. Use ScaleOut’s AppFabric Caching Compatibility Library
  2. Migrate to native ScaleOut APIs for extended functionality
