IMHO yes,

we want to run this kind of setup in produktion soon. We have choosen
to use Cyrus Murder to ease failover.

Each server will run 1 frontend, 1 backend and 1 replication server
in case of failure of one server the corresponding replic will become
backend.  If the failed server is back onlie we will use replication to
bring the original backend up to date.

We will use ClusterIP for loadbalancing the Frontend connections.
