If you asked ten random techies to define "cloud computing," you might get twelve or thirteen different answers, but if instead you asked those same ten folks to identify the most overused buzzword of the last year, they'd probably all agree that "cloud computing" was it. So imagine my surprise when, on attending a session at this past summer's AlwaysOn conference, I heard someone on the stage talk intelligently, coherently, and technically about a topic that I had written off as so much noise. That person was HP's Russ Daniels, CTO and VP of Cloud Services Strategy, I had to talk to him in more detail about cloud computing. This interview actually altered the way I thought about the cloud and about software delivery in a networked world.
After a lot of hype this sounds like a common sense approach to assesing cloud computing. This interview is covered on Ars technica.
Suggest you just sit there and wait till life gets easier.
