Cloud computing is the use of computing resources (hardware and software that are delivered as a service over a network(typically the Internet). The name comes from the use of a cloud-shaped symbol as an abstraction for the complex infrastructure it contains in system diagrams. Cloud computing entrusts remote services with a user’s data, software, and computation. The cloud providers manage the infrastructure and platforms on which the applications run. SaaS is sometimes referred to as ‘on “demand software” and is usually priced on a pay per use basis. Saas providers generally price applications using a subscription fee.
End users access cloud-based applications through a web browser or a light weight desktop or mobile app while the business software and user’s data are stored on servers at a remote location. Proponents claim that cloud computing allows enterprises to get their applications up and running faster, with improved manageability and less maintenance, and enables IT to more rapidly adjust resources to meet fluctuating and unpredictable business demand.
Cloud computing relies on sharing of resources to achieve coherence and economies of scale similar to a utility (like the electricity grid) over a network. At the foundation of cloud computing is the broader concept of converged infrastructure and shared services.
