Heard this on the radio, a company offering cloud services in there data center, so now the cloud services have moved to the data-center, but in this case just it sounded in my humble opinion one data-center. well that will work!, But I thought that to original premise of a cloud was that it was utility computing, on a service that was distributed, so that if one data-center goes down the data-center in a different location will stay up. so spend your money wisely, a cloud service needs to be distributed, and clustered. That it would have at a minimal specification two of everything, one of each located in a different building on a separate power gird, and preferably power from a different supplier. I think that too many sales persons have swallowed the book on cloud computing, but have only glanced at the specification rather than the detail.
