At VMWorld, I attended the keynote from VMware CEO Diane Greene on the first day. It was standing room only -- and she mentioned that four years ago at the first VMWorld held in San Diego 1,500 people attended. In 2007 in San Fran there were about 11,000. That’s just a little bit of growth! What's the appeal for you in Virtualization? Why is it such a hot button right now?

I recently attended the VMWorld Virtualization show in San Francisco. I’m sure I’m not alone in thinking, “This is not new.” Virtualization has been around for almost 40 years: IBM developed it on mainframes back in the late '60s. In those days of “the Glass House," uptime was a critical focus for the system operators, and mainframes were built differently from Intel/Windows boxes. Now that people are looking at going back to multiple virtual machines on a single physical machine, who is worrying about what happens if that physical machine crashes?
