Hello, I am thinking about using the keystone as an authentication system but I am afraid about failures which can affect all the cluster. In fact if the keystone server dies then our full cluster will stop. It would be better if we could use HA with the keystone. Then if our primary keystone server dies we have to elect a new primary keystoe server. Are there some tools which can be used in HA deployment? Any piece of advice will be valuable Sincerely, Alexandr -------------- next part -------------- An HTML attachment was scrubbed...
