What is Cloud Computing? Wikipedia defines it as the provision of computational resources on demand via a computer network. Users or clients can submit a task, such as word processing, to the service provider, such as Google, without actually possessing the software or hardware. The consumer's computer may contain very little software or data (perhaps a minimal operating system and web browser only), serving as little more than a display terminal connected to the Internet. Since the cloud is the underlying delivery mechanism, cloud based applications and services may support any type of software application or service in use today.
Cloud computing is all the rage. "It's become the phrase du jour," says Gartner senior analyst Ben Pring, echoing many of his peers. The problem is that (as with Web 2.0) everyone seems to have a different definition. As a metaphor for the Internet, "the cloud" is a familiar cliché, but when combined with "computing," the meaning gets bigger and fuzzier. Some analysts and vendors define cloud computing narrowly as an updated version of utility computing: basically virtual servers available over the Internet. Others go very broad, arguing anything you consume outside the firewall is "in the cloud," including conventional outsourcing.

The public may not be familiar with the term, but many are already doing cloud computing. We have been using Web applications for years without any concern about where the applications actually run. The Pew study found that 69 percent of Americans connected to the Web—and especially younger users—already use some kind of cloud service, such as Web email (Gmail, Yahoo! Mail or Hotmail), online data storage (IDrive, Mozy, Box.net) or online software.
