What do you need to set up a cluster with JBoss?

What is JBoss JGroups?

JBoss uses a tool called JGroups to enable peer-to-peer communication between nodes. JGroups is a toolkit for reliable multicast communication. It uses existing network infrastructure and protocols to transmit multicast messages that are reliable because receivers can request retransmission of lost packets of data.

Can you create a cluster in standalone mode?

As previously mentioned, to get clustering capabilities you need to use either the ha profile or the full-ha profile. We will stick with the ha profile for now. In standalone mode, this means that your configuration file is meant to be the one named standalone-ha.

How do I cluster a JBoss web server for ha?

The web server itself can be clustered for HA, using one of several compatible load balancing mechanisms.
