Jumping Into Terracotta

Abstract

Terracotta delivers a transparent scale-out model to Java programming. The lightweight nature of the development model is inherent in the fact that the software plugs in to an offthe-shelf JVM and allows developers to write applications without explicit in-memory replication or mapping data to an underlying data store. Those applications then spread across machines at run time. The point of such an approach is not just for scale but for high availability. Based on knowledge gained from some of the largest scale applications in the world, Terracotta helps you achieve scalability and availability with less effort. Let’s now take a look at a system that illustrates ease, scale, and availability in a short, “hello world” style program.
