Cloud computing provides computation, software, data access, and storage services that do not require end-user knowledge of the physical location and configuration of the system that delivers the services. Parallel to this concept can be drawn with the electricity grid, wherein end-users consume power without needing to understand the component devices or infrastructure required to provide the service.
How the Cloud Works
Cloud computing describes a new supplement, consumption, and delivery model for IT services based on Internet protocols, and it typically involves provisioning of dynamically scalable and often virtualised resources. It is a byproduct and consequence of the ease-of-access to remote computing sites provided by the Internet.
This may take the form of web-based tools or applications that users can access and use through a web browser as if the programs were installed locally on their own computers.
