Hello,

Currently we have a customized setup of HA clustering of CAS 3.5.2 which
involves two servers (one primary, one failover) with a mySQL master-master
replication.  The database caches ticket-granting tickets in case of
failover to the 2nd server.

We've had multiple issues with the master-master replication, and we are
also planning to introduce a 3rd server in the cloud.

Is the EhcacheTicketRegistery still the best method for clustering multiple
servers?  We will have to use RMI since multicasting is not an option in
AWS.

If we use the EhcacheTicketRegistery, can we switch to a load balanced
setup instead of having a primary/failover setup?

Thank you,
