Caching overview

WebSphere® eXtreme Scale can operate as an in-memory database processing space, which you can use to provide in-line caching for a database back-end or to serve as a side-cache. In-line caching uses eXtreme Scale as the primary means for interacting with the data. When eXtreme Scale is used as a side-cache, the back-end is used in conjunction with the data grid. This section describes various cache concepts and scenarios and discusses the available topologies for deploying a data grid.
