Definitions

The topic is being broken up into three sections:

• Federation (a set of distributed exchanges and queues, seperately managed and wired together)
• Clustering (a set of distributed exchanges and queues managed as a single entity)
• HA / Fault tolarance (the ability for exchanges and queues, clustered, federated, or isolated to replicated important state to a backup (failover partner))
• Failover (the ability for a client to reconnect to the failover partner)

Requirements/Use Cases

• Reliability Requirements
• ClusteringAndFederation
