With WebSphere® eXtreme Scale,
your architecture can use local in-memory data caching or distributed
client-server data caching.
WebSphere eXtreme Scale requires
minimal additional infrastructure to operate. The infrastructure consists
of scripts to install, start, and stop a Java™ Platform, Enterprise Edition application on a server.
Cached data is stored in the eXtreme Scale server, and clients
remotely connect to the server.
Distributed caches
offer increased performance, availability
and scalability and can be configured using dynamic topologies, in
which servers are automatically balanced. You can also add additional
servers without restarting your existing eXtreme Scale servers. You can
create either simple deployments or large, terabyte-sized deployments
in which thousands of servers are needed.
