We are happy to announce availability of the preview for Windows Azure Caching with the latest SDK release of Azure SDK which you can download here:
http://www.windowsazure.com/en-us/develop/downloads/. This preview enables a low latency, in-memory distributed cache as a part of your own application. The cache is isolated for use just by
your application and does not have any throttling limits. The cache role instances can dynamically grow and shrink like any Azure roles. It supports the full richness of AppFabric Cache Server API and also supports the memcache protocol, allowing you to point
code written against Memcache to it and run without changing any code.
