What exactly is cloud computing?
In the gold rush, many general IT vendors are becoming cloud computing vendors – or at least touting their products as such. In the same way that the lowly pretzel, once merely a salty snack, is now “low cholesterol,” these days every new app is Specially Designed for the Cloud.

“…a style of computing in which scalable and elastic IT-enabled capabilities are delivered as a service to external customers using Internet technologies.”
Translated into human-speak: We’ll access our software over the Web, instead of on our hard drive.
