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.
