8.13. Protocol Clustering

Both JBossESB replication and JMS clustering can be used together. For example, Service A is identified in the registry by a single JMS end-point reference. However, invisibly to the client, the JMS end-point reference is pointing to a clustered JMS queue, which has been separately configured to support three services. This is a federated approach to availability and load balancing.

If your provider simply cannot provide any clustering, you can add multiple listeners to your service and use multiple (JMS) providers. However this will require fail-over and load-balancing across providers which leads us to the next section.
