Cloud computing

Cloud computing promises to increase the velocity with which applications are deployed, increase innovation, and lower costs, all while increasing business agility. As a metaphor for the Internet, "the cloud" is a familiar cliché, but when combined with "computing," the meaning gets bigger and fuzzier. 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, training new personnel, or licensing new software. It encompasses any subscription-based or pay-per-use service that, in real time over the Internet, extends its existing capabilities. It allows supporting every facet, including the server, storage, network, and virtualization technology that drives cloud computing environments to the software that runs in virtual appliances that can be used to assemble applications in minimal time. This paper discusses how cloud computing transforms the way we design, and deliver applications, and the architectural considerations that enterprises must make when adopting and using cloud computing technology. It is a better way to run your business. Instead of running your applications yourself, they run on a shared data center. Cloud Computing has generated a lot of interest and competition in the industry. With the emergence of new Cloud Providers, identifying one that best suits the business needs of an enterprise is a challenging and difficult task. Each of the Cloud providers have their own set of pricing, billing, flexibility, support and other important parameters in their model of computing the service. Cloud computing is broken down into three segments: "applications," "platforms," and "infrastructure." Each segment serves a different purpose and offers different products for businesses and individuals around the world.

A paradigm shift to cloud computing will affect many different sub-categories in computer industry such as software companies, internet service providers (ISPs) and hardware manufacturers. Finally, cloud applications don't eat up your valuable IT resources. This lets you focus on deploying more applications, new projects, and innovation. Cloud computing is a simple idea, but it can have a huge impact on your business.
