Cloud computing is a form of Internet-based computing that provides shared computer processing resources and data to computers and other devices on demand.[1] It is a model for enabling ubiquitous access to a shared pool of configurable computing resources (e.g., computer networks, servers, storage, applications and services), which can be rapidly provisioned with minimal management effort. Cloud computing allows users and enterprises with various capabilities to store and process data in either a privately owned cloud, or on a third-party server in order to make data accessing mechanisms more efficient and reliable. Data centersthat may be located far from the user–ranging in distance from across a city to across the world. Cloud computing relies on sharing of resources to achieve coherence and economy of scale, similar to a utility.
