Also running ehcache with JSON service registry. 3 node cluster in both test
and prod behind Cisco ACE load balancers.

We switched from memcache-repcache for tickets and /MySQL for service registry
to using replicated ehcache for the ticket registry and JSON service registry
(We manage with puppet, but git/cron would work just as well.) This sits
behind an apache load balancer. From a clustering standpoint it works great
for us.

Dear Community,
We are looking to build a High Availability CAS solution for our campus
rather quickly. We currently have two CAS app VMs sharing tickets with a
single database as a single point of failure. We have F5 in front to
load-balance traffic.
What are some high level architectures for HA you have implemented?
We have a 2-node CAS cluster behind a load balancer. The ticket registry is
stored in memcache+repcache. CAS connects to memcache on the localhost and it
is replicated to the other node.
The service registry is stored in MySQL. CAS continues to process
authentications while MySQL is down (note: see issue CAS-1458), although you
cannot make changes to services, of course.
