eXtreme Scale

WebSphere eXtreme Scale is an elastic, scalable, in-memory data grid. It dynamically caches, partitions, replicates, and manages application data and business logic across multiple servers. It can be used in many different ways, such as a powerful cache, an in-memory database processing space, or to build Extreme Transaction Processing (XTP) applications.WebSphere eXtreme Scale offers a Stand-alone environment installation (Standalone offering for both Client and Server), an installable on WebSphere Application Server Network Deployment (Embedded offering for both Client and Server), and an eXtreme Scale Liberty Deployment (XSLD) and eXtreme Scale Liberty Client feature installable to Liberty servers.WebSphere eXtreme Scale is made up of clients, catalog servers, and container servers. Clients will first connect to catalog servers to obtain metadata about the grid and the location of container servers, along with how data is distributed across them. The client then connects to the correct container server to obtain the requested data.WebSphere Extreme scale servers(Containers) can be used as a Dynamic cache provider for WebSphere Application Server, an HTTP Session Persistence store for J2EE application servers, and can be used as a Simple Data grid. Containers consist of shards, which represent a partition of data. Multiple shards which represent different partitions can exist on a single container. Each partition has an instance which is a primary shard, and a configurable number of replica shards which are used for failover.
