Cloud Computing is a type of Internet-based computing that provides shared computer processing resources and data to computers and other devices on demand. It is a model for enabling ubiquitous, on-demand access to a shared pool of configurable computing resources, which can be rapidly provisioned and released with minimal management effort. Cloud computing and storage provide users and enterprises with various capabilities to store and process their data in either privately owned, or third-party data centers that may be located far from the user. Cloud computing relies on sharing of resources to achieve coherence and economy of scale, similar to an electricity grid over a network.
Cloud Computing allows companies to avoid up-front infrastructure costs, as well as enables organizations to focus on their core businesses instead of spending time and money on computer infrastructure. Proponents also claim that cloud computing allows enterprises to get their applications up and running faster, with improves manageability and less maintenance. Information Technology teams can easily adjust resources to meet fluctuating and unpredictable business demand.
