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
