Definitions
- Federation (a set of distributed exchanges and queues, seperately managed and wired together)
- Custer for Reliability/Fault Tolarance
- Cluster members replicate state.
- If one cluster fails, clients can fail-over to another.
- Cluster for throughput
- Distribute load to multiple brokers for higher throughput.
NOTE: clustering for reliability and throughput have very different goals.
They can be combined: e.g. distributing load across a set of reliable primary-backup pairs.
