You can integrate WebSphere® eXtreme Scale with other server products, such as WebSphere Application Server and WebSphere Application Server Community Edition.
WebSphere Application Server Community Edition can share session state, but not in an efficient, scalable manner. WebSphere eXtreme Scale provides a high performance, distributed persistence layer that can be used to replicate state, but does not readily integrate with any application server outside of WebSphere Application Server. You can integrate these two products to provide a scalable session-management solution. See Configuring the HTTP session manager to work with WebSphere Application Server Community Edition for details.
The HTTP session manager first shipped with WebSphere Extended Deployment DataGrid Version 6.1.0.0. Subsequent versions through Version 6.1.0.5 have not changed the utilization methods, since it meets the Jave 2 Enterprise Edition (J2EE) specification for integration and session retrieval, but there have been performance and QoS enhancements with every release. To ensure you are getting the best quality of service, the recommendation is to apply the WebSphere eXtreme Scale version 6.1.0.5 Fix Pack.
