I think that about sums it up for now. Internal clouds, sure. Public clouds are a different story. The cloud as Microsoft is picturing it has amazing potential. It seems like a person savy in both cloud concepts and business principles could create an incredible business with minimal up front costs and easy scalability as the business grows.

On the other hand, there's that nagging problem of hackers. I once had a hamster. I came home one day and found the hamster systematically gnawing on every bar in its little cage. It looked cute but silly. I few days later, the hamster escaped. I still don't know how. When your lifetime, all-consuming job is to escape a cage, even a hamster can figure out how to do it. There are people out there who seem to feel that their life calling is to hack networks whether for profit or just mischeif. It will take just one situation where someone builds a really big business in the cloud and the business gets destroyed by a hacker to add a dose of harsh reality to this concept very quickly.
