Pacemaker: OpenStack’s PID 1

My name is David Vossel. I’m a core developer of the Pacemaker project and author of Pacemaker Remote. I want to share our success with scaling the Pacemaker cluster resource manager to meet the requirements necessary automate recovery of OpenStack controller and compute nodes.

OpenStack’s architecture consists of a set of distributed components capable of scaling horizontally across 100s and even 1000s of nodes.
