OpenStack High Availability Guide¶

This guide describes how to install and configure OpenStack for high availability. It supplements the Installation Tutorials and Guides and assumes that you are familiar with the material in those guides.

This guide documents OpenStack Ocata, Newton, and Mitaka releases and may not apply to EOL releases Kilo and Liberty.

This guide is a work-in-progress and changing rapidly while we continue to test and enhance the guidance. There are open TODO items throughout and available on the OpenStack manuals bug list. Please help where you are able.
