Download Description

IBM WebSphere eXtreme Scale is an elastic, scalable in-memory data grid that provides a key-addressable store of values or graphs. This product supports a processing unit, state store for applications written in Java. You can replicate the data stored in the data grid, depending on availability requirements, and you can achieve out-of-the-box database integration.

WebSphere eXtreme Scale can be integrated with existing WebSphere Application Server and WebSphere Application Server, Network Deployment installations, or you can install the stand-alone product.
