Here is an article we came across the morning by Dan Kusnetzky of ZDnet that points out the difference between Cloud Computing and Virtualization.
I came across an interesting post, Is Virtualization the Same as Cloud Computing?, published by Rajan Chandras. He, in turn, was commenting on an article that equated cloud computing and virtualization. He’s arguing that it is incorrect to equate virtualization to cloud computing.
I believe that both Rojan and I would agree that virtualization is abstracting computing functions into a logical environment that appears ideal for that function that may be very different than the actual physical environment. This trades computing and other resources for flexibility, scalability, performance, reliability or some other requirement. In my view, this breaks down to seven layers of technology, each of which contains several different segments. (see Sorting out the different layers of virtualization for more information on my model.)
