Cloud Computing is computing on the Internet. Data and applications are stored and run on a server that a user’s computer accesses often via a web browser.
The “old” way of computing was to install a program on a workstation such as a home computer, then access and save any files on that same computer or a server within a closed network.
Cloud computing takes away the need for installation and storage on a workstation as all the data is processed and stored remotely in the “cloud” somewhere on the Internet. It means that workstations can be simpler devices which are still able to perform complex computing as the hard work is done by another computer and all the workstation has to do is send requests and show the results.
