ActiveCluster maintains a list of Nodes Node objects, each Node representing a member of the cluster Cluster.
A node can optionally have some local state which is replicated to other members of the cluster.


Messaging abstraction

In addition the Cluster (the group of nodes) and each Node in the cluster have a Destination. The other part of the ActiveCluster API is a simplified facade to messaging - way simpler and more abstract than JMS - which allows you to send application level messages to the cluster as a whole or to individual members of the cluster.


We can create sophisticated slicing & dicing of the cluster, participants, state replication and application message flow using standard JMS techniques
