Cloud computing refers to a convergence of technologies and trends that are making IT infrastructures and applications more dynamic, more modular, and more consumable. That’s a big change that has implications that touch on just about every aspect of computing. This whitepaper aims to make sense of it all for audiences that haven’t been deeply involved in the details of cloud computing as it has rapidly evolved. It lays out the characteristics of a cloud computing infrastructure. It discusses some of the things that cloud computing isn’t, even if they’re often conflated in customers’ and prospects’ minds.
