And I don't understand why you get insightful for your comment :).
There is a big difference between a traditional approach to IT, which involves fileservers, SAN, mailboxes, ... and a "private cloud" approach. What most techies do not comprehend, is that cloud computing is not a technology, but *a delivery model* for ICT services. Any existing service can be wrapped in a cloud coating, if that service is delivered in another way, to adhere to some fundamental characteristics of cloud computing (see for example the NIST definition). That is: you need to deliver your service anywhere, anytime, from any device (ubiquitous access), it needs to be in a self-service form, it needs to scale elastically (without waiting weeks for new servers to be delivered, ...), etc. Those are service characteristics that in the end will of course use technologies such as a SAN or fileserver or mailserver to deliver that service. It's just one logical layer higher than the technological layer.
People who claim that cloud computing is "old stuff", have not understood what cloud computing is about.
