Hi,

By reading following URL, I find two ways of HA method for Keystone (Identity) API. by using HAProxy and by using Pacemaker.

https://docs.openstack.org/ha-guide/c...

https://docs.openstack.org/ha-guide/c...

Why Keystone is so special so it has/require these two ways? Or, do I miss something here?

Best regards,

Keystone is not special compared to other services. When you read on, you will find that the guide also covers pacemaker for Glance and Cinder high-availability. It does leave out Nova and Neutron.

HA-proxy is sufficient to make everything HA (except cinder-volume and nova-consoleauth, which don't support active/active mode).

I believe that the HA guide has never been completed. Consider it a set of suggestions, not a guide that was designed end-to-end. Personally, I am familiar with the HA of Helion OpenStack, which might be a good source of inspiration. See https://docs.hpcloud.com/hos-5.x/#hel....
