Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. IBM WebSphere eXtreme Scale is the IBM in-memory datagrid product. It can be described as a fully elastic memory based storage grid. It virtualized the free memory of a potentially large number of Java virtual machines and makes them behave like a single key addressable storage pool for application state. Applications can view this as a network attached storage medium. It is key addressable and applications can store a value at a key. Data within the grid can be replicated to achieve fault tolerance and protect against data loss. It can also be written to relational databases and any other persistence backend using write through or write behind technologies. Data can be automatically pulled from a backend such as a relational database or enterprise application if it isn't present in the gridlogies. Data can be automatically pulled from a backend such as a relational database or enterprise application if it isn't present in the grid.
