The WebSphere Application Server provides
a Dynamic Cache service available to deployed Java EE applications.
This service is used to cache business data, generated HTML, command
output, etc. Initially, the only provider for the Dynamic Cache service
was the default dynamic cache provider that is built into the WebSphere
Application Server. Today customers can also specify WebSphere eXtreme
Scale to be the cache provider for any given cache instance. This
enables applications that use the Dynamic Cache service, to use the
features and performance capabilities of WebSphere eXtreme Scale.
