I've been doing research lately on WHM's, primarily looking for which one has the best options for redundancy. It looks like most of the WHM's don't really care about that. Can I get some oppinions on some of the current setups that people have to implement some sort of redundancy?
What I'd ultimately like to see is two servers that have a backdoor network, where the master replicates to the slave, and in the event that the master becomes unavailable for whatever reason, the slave becomes available. Doing all this should not require load balancers or any other outside hardware/software setups. The servers should communicate via heartbeat and update eachother constantly. There should be some sort of mesh setup available for redundant DNS, Mail, Web, etc etc.
Those are just some of the things I'm looking for. Anyone have any suggestions?
