High Availability is a key concept in private and public cloud infrastructures. In this session, we explain high availability in the OpenStack Essex and Folsom releases. Specifically, the session covers high-availability considerations for OpenStack services such as Cinder, Nova, Keystone, Glance and Horizon. It also outlines high-availability aspects of Swift and Ceph storage, and high availability for infrastructure services such as MySQL and RabbitMQ. This includes techniques for integrating OpenStack with Pacemaker, the ubiquitous and universal high-availability stack for the Linux platform.
Attendees should have a good understanding of OpenStack components. Prior knowledge of the Pacemaker stack is a plus, but not a requirement.
