This is the demonstration of the flow of REST API requests between key services that comprise OpenStack Compute, exactly as it happens when one provisions a virtual machine. The information is accurate as of OpenStack Essex release.

Mirantis uses this exact deck for one of the modules of its 2-day OpenStack BootCamp (see http://www.mirantis.com/training ).

We have published it due to popular demand and multiple requests to make it publicly available. Enjoy!
