At the Folsom design summit, OpenStack developers decided we would embrace infrastructure high availability, a standard feature in other cloud stack solutions. Infrastructure HA is particularly important to those users who are looking to OpenStack as a means of data center consolidation involving legacy applications, and who are not at liberty to execute a major application redesign from the ground up.
Since then, we have had seen the addition of an in-progress High Availability Guide, we have contributors writing integration code for the Pacemaker high-availability stack (the standard Linux HA infrastructure layer), and OpenStack is rapidly improving in high availability features. We are also seeing exciting progress in storage technologies like Swift and Ceph, which come with high availability built-in.
This session is a progress report and outlook on high availability features in Folsom and Grizzly.
