The use of virtualization to enable utility computing has become pretty well accepted over the past year. So much so, that it’s almost comical to think of some of the responses we got three years ago when we started 3tera and were touring VCs and potential partners with our Powerpoint slides.
Unfortunately, some folks take the idea too literally and believe that virtualization and a SAN is all that’s required. Of course, nothing could be further from the truth. AppLogic has been in production for 18 months and EC2 for twelve, so we now have data about what services are required for utility computing.
Peter and I just finished an article for fishtrain that discusses how virtualization fits into utility computing and what additional services are required. Hopefully it’ll stir a little bit of discussion.
