Network World: Do you think virtualisation is being overhyped?
John Fowler: I don't think its being overhyped. It's a little surprising when you think about what's happening. Unix systems and mainframes have actually had virtualisation for a long time. This isn't new to a big chunk of the market. All of us and people over at IBM are probably kind of puzzled too, because actually IBM invented virtualisation in the mainframes in the '60s.
What's happened is it's come to the x86 market. That's why it's suddenly a part of the popular press because you never could virtualise Windows before. The second thing is the sudden emphasis on energy efficiency and people see it as a way to solve that problem as well.
