Hello everyone,

I'm working for a school project, which is about openstack. This project lasts two years. Last year, I mount an openstack infrastructure but with any redundancy. This year, i would like to implement high-availability. Unfortunately, recently openstack-ha guide has been removed, and architecture guide seems to be not complete. So, there is my question:

  1. Can i move a simple architecture (controller node, compute, block storage) to a high availibility infrastructure ( obviously, if it is possible I'd like to keep my current configuration. I already configured galera cluster)

  2. Is it possible to make HA in a multi-site environnement ?

  3. Is it a documentation which is talking about this topic and if yes, where can i find it ?

Thank you very much for all people who take the time to read my topics and sorry if my english is bad

Some OpenStack distributors document their HA approach. The one I know best is SUSE OpenStack Cloud 8, see https://www.suse.com/documentation/su... and following pages. It’s a good learning resource. I believe Red Hat does it as well.

Thank you Bernd Bausch, it will be helpful.

For information, Openstack community have just begun to rewrite their documentation.

If anyone has an additional idea to submit it will be with pleasure.
