Hi, I've been trying to figure out exactly what the origin of the component naming is.

I think that the Release Naming scheme makes sense, and is somewhat well understood.

Anyone know the history?

Here are my guesses based on the list from

  1. Compute (Nova): because it came originally from NASA Ames?
  2. Object Storage (Swift): ???
  3. Image Service (Glance): ???
  4. Identity (Keystone): because identity is the "keystone" to security?
  5. Dashboard (Horizon): ???
  6. Networking (Neutron): Was quantum but change because of a trademark issue. But why neutron?
  7. Block Storage (Cinder): because of "cinder block"
  8. Telemetry (Ceilometer): ceilometers measure things
  9. Orchestration (Heat): ???
  10. Database Service (Trove): ???
  11. Data processing (Sahara): ???
  12. Bare metal (Ironic): A "ironic" play on the word "iron"?
  13. Queue service (Zaqar): ???
  14. Key management (Barbican): Barbican is a fortified gateway to a castle
  15. DNS Services (Designate): ???
  16. Common Libraries (Oslo): ???
