What is cloud computing?

  • —  It basically refers to the Computing power ‘On demand’ to customers.
  • —  Brief History : 1960 John McCarthy predicted that someday computing will be organized as a public utility, and eventually his idea converted into :—  Grid computing which is now being advanced to Cloud computing.

    Grid Computing refers to the application of multiple computers with various resources over a network to solve a single problem at the same time. Usually to a scientific or technical problem that requires a great number of computer processing cycles or access to large amounts of data.

    Cloud Computing is the one which uses the internet and central remote servers to maintain data and applications. Cloud computing allows consumers and businesses to use applications without installation and access their personal files at any computer with internet access.

  • —  Cloud computing is a set of technologies that allows computing applications and data to be exposed as a set of services from a pool of underlying resources.
  •    So, the benefit is : ‘Install an application only once, and run it as many times for any number of systems’ rather than installing and configuring for each system
