OpenStack
integration
REST APIs
RPC Messaging
Database state storage
Client gets auth token from Keystone
Client calls Nova REST API
Nova API validates Keystone token
Nova API makes DB entry for instance and returns instance ID to client
Nova API puts message on bus for scheduler
Scheduler queries DB for available compute resources
Scheduler puts message on bus for compute
Compute puts message on bus for Conductor to fetch DB info
Conductor fetches DB info and returns it to Compute in bus message
Glance validates compute's creds
Glance returns image details
Compute makes REST call to Neutron to get network config
Neutron validates compute's creds
Neutron returns network details
Compute compiles data into format for HV and executes
Compute puts message on bus for Conductor to write DB info for instance
Client makes REST calls to track instance build data
Compute makes REST call to Glance for requested image
OpenStack
project structure
Each project has own git repository
Changes gated by Gerrit
Core reviewers and automated CI
Community elected PTL for decisions
Launchpad for issue tracking
Major releases every 6 months
Stable branches with three phases for 18 month lifespan
Light barrier to entry
Large conferences every 6 months
Small subject mid-cycle meetups
