Improving Java Application Performance: Maximizing Scalability and Availability
Java applications are easiest to write and test when they run in a single JVM. However, the requirements to make applications scalable and highly available have forced Java applications to run on more than one JVM. This pressure has caused a proliferation of solutions that have encumbered the architectures of many Java applications.
Terracotta's Network-Attached Memory (NAM) is an arbitrarily large, network-attached Java heap that lets threads in multiple JVMs on multiple machines interact with each other as if they were all in the same JVM. NAM is a fast, simple, and reliable way to add commodity servers to your application's deployment architecture to provide scalability and high availability without torturing your application architecture, overloading your database, and distracting your development team from delivering features.
