Distributed Messaging for OpenStack

This page was created to outline the core requirements for messaging in OpenStack and how to achieve those requirements in a reliable, performant and resilient way.

Core Design Principles

  • Fully distributed design?
  • Easy failover
  • Scalable == Federatable

Current thoughts

RabbitMQ and Qpid are troublesome. 0MQ doesn't have the support that it needs. I think we need something pure python and much simpler than the current messaging infra to take care of all this stuff. A pure-python easily understood implementation will attract maintainers and people interested in extending things.

Use Cases

  1. Cloud failures along availability zones
  2. One to One (host to host or service to service)
  3. One to Many
