We started the chapter with XTP. XTP systems require high-performance, high-scalability, and strong manageability. In the past years, we've had middleware that supply all three to varying degrees of success. IMDGs are new tools used to build XTP-class software due to their leaps forward in scalability and manageability. Co-locating data and application logic in the same JVM offers huge performance increase over previous generations of tools.

A common requirement when using IMDGs is a reduction of network hops. Accessing data stored exclusively in different ...
