6th Circle of Hell: Heresy. This circle houses administrators who accurately set up a cluster to use Buddy Replication. Without caring about steady sessions.
Clustering allows us to run applications on several parallel instances (also known as cluster nodes). The load is distributed across different servers, and even if any of the servers fails, the application is still accessible via other cluster nodes.

In this chapter, we will cover the basic building blocks of JBoss Clustering with the following schedule:
A short introduction to JBoss Clustering platform
In the next section we will cover the low level details of the JGroups library, which is used for all clustering-related communications between nodes
In the third section we will discuss JBoss Cache, which provides distributed cache and state replication services for the...
