I’ve spoken at various times in this space about the benefits of virtualization. Recently I was presenting at a technical education event sponsored by the mega-distributor TechData, and the gentleman in the next room over was conducting a VMware seminar. I asked him what he considered the major benefit of virtualization these days; his reply was “disaster recovery.” In his view, the cost savings aspect of virtualization was “yesterday’s news.”
In addition to benefits from disaster recovery and cost savings are benefits associated with flexibility (that is, the ability to dynamically reallocate hardware resources more easily than one can do with physical machines) and optimization (the ability to run a single VM for a single purpose, such as for example DHCP, and set up that VM so that its configuration is tuned for what’s best for DHCP without regard to any other roles).
So, I’m interested: What do you think is the biggest major benefit to virtualization? Is it disaster recovery, cost savings, flexible resource allocation, or the ability to optimize single-purpose servers? Or is there another benefit that you think is even more important than these four? Let us know.
