Which should I choose Clustering or Virtual Machine Replication?
I was chatting with a Kusnetzky Group client the other day and he asked a question that seemed to have an obvious answer at first but, seemed more complex as we discussed it. The question was should his organization deploy a clustered solution, such as SteelEye's LifeKeeper or encapsulate applications and use a virtual machine replication technology, such as VMware's Vmotion, XenSource's Xenmotion or Virtual Iron's Virtual Iron, to accomplish something that seemed similar.
