• High Availability/Grid

• JBoss Clustering

• JBoss Cache

• JGroups

High Availability and Grid projects allow you to distribute your applications across a network in order to remove single points of failure, increase reliability and improve performance.

Structured in a hierarchy, the projects build upon each other to create increasing levels of abstraction above the network layer. Applications then use the levels they need according to their requirements. For example, the clustering features of JBoss AS are provided by JBoss Clustering, the distributed caching features of Hibernate are provided by JBoss Cache and the distributed messaging features of JBoss Messaging are provided by JGroups.
