Question

what is cloud computing

Answer 1

In the simplest terms, cloud computing means storing and accessing data and programs over the Internet instead of your computer's hard drive. The cloud is just a metaphor for the Internet. It goes back to the days of flowcharts and presentations that would represent the gigantic server-farm infrastructure of the Internet as nothing but a puffy, white cumulonimbus cloud, accepting connections and doling out information as it floats.

Answer 2

cloud computing enables companies to consume compute resources as a utility --just like the electricity-- rather than having to build and maintain computing infrastructures in -house
