The CAS4 documentation has a thoughtful section on high availability that should be your starting point: http://jasig.github.io/cas/4.0.0/planning/High-Availability-Guide.html I have no experience with database clusters, but substantial experience with HA LDAP infrastructure. If LDAP is your authentication store, I would strongly recommend a master-slave topology where the master may or may not be among the hosts that handle CAS authentication. You really SHOULD have a hardware load balancer in front of the nodes. With CAS4 there is a reasonable facility to connect to multiple LDAP hosts in a fairly performant way, but load balanced pools with a single virtual address are preferable. DNS round-robin is totally unsuitable for HA for reasons discussed in the document above. I believe many of the HA concerns around LDAP are applicable to a HA database infrastructure.
