What’s a cloud anyway? Copyright 2008 SpringSource. Copying, publishing or distributing without express written permission is prohibited. The cloud is a metaphor for the Internet (..) and is an abstraction for the complex infrastructure it conceals. It is a style of computing in which IT-related capabilities are provided “as a service” , allowing users to access technology-enabled services from the Internet "in the cloud" without knowledge of, expertise with, or control over the technology infrastructure that supports them.
