I have a virtual env with 2 VMs (or the same host) in which I run several application on top of a RHEL OS.
What I was looking for is what are the options (maybe pros/cons) to achive app. HA between the VMs.
In order to have, in case a appl. fails on the VM#1, it would automatically failover to the VM#2 (even if the VM#2 is on the same host or not).
I checked the VCS (Veritas) for ESX and the App HA.... but I dont know much about them...
Can you guys maybe point out reliable articles and if in your opinion one is better than the other in terms of easy to implement, less cost, more reliabel..etc?
