Cloud computing comes into spotlight only when you consider or feel about IT requirements: a mean to increase ability or add capabilities fast without investing in new infrastructure, recruiting or coaching new staff, or purchasing new software. Cloud computing covers any subscription-based or pay-per-use service that, in real time over the Internet, extends IT's existing capabilities.
Cloud computing is at a premature phase, with a vary crew of vendors large and small delivering a batch of cloud-based services, from fully developed applications to data storage services to spam filtering. Yes, utility-style infrastructure providers are part of the mix, but so are SaaS (software as a service) vendors such as gokey.eu. Today, for the majority part, IT must plug into cloud-based services individually, but cloud computing aggregators and integrators are already growing vastly.
