What is Cloud Computing? Its nothing but sharing computer resources instead of using any software or the local storage. Its everywhere. Its in business, entertainment, education. Though it is in its infancy state it will be one of the promising technologies in future.
Cloud computing comes into focus only when you think about what IT always needs... a way to increase capacity or add capabilities on the fly without investing in new infrastructure, or licensing new software. Cloud computing encompasses any subscription-based or pay-per-use service that, in real time over the Internet, extends IT's existing capabilities. Different people have different perspectives on it.
Views of different people on Cloud Computing
"It's stupidity. It's worse than stupidity: it's a marketing hype campaign. One reason ypu should not use web applications to do your computing is that you lose control."
- Richard Stallman, FSF Founder
"I think whether you're an enterprise or an individual, it rarely makes sense for you to have your own buildings, fiber cables and infrastructure. It takes a lot of time and effort to maintain. Ultimately, your resources are available to you wherever you are, and you want those things there. There's an economy of scale that makes that easier and more powerful because there's a lot of interoperability that's not otherwise possible. there's less time-burn in managing your digital life."
- Sergey Brin, Google Co - Founder
"Cloud computing is the future of Open Source"
- Jonathan Schwartz, CEO, Sun Microsystems
"In the extreme case, we can take somebody's data center and run it for them on the cloud. All the issues about administrative, capacity, who owns the data, what happens when things go wrong, when people are getting error messages, that's cloud computing and there is a lot of deep invention and work."
- Bill Gates, Co - Founder of Microsoft
