What is cloud computing?

Cloud computing is Internet-based computing, whereby shared resources, software and information are provided to computers and other devices on-demand, like electricity.

Cloud computing is the management and provision of applications, information and data as a service. These services are provided over the internet, on a consumption-based model.  I.e. pay per usage.

Cloud provides a convenient way of accessing computing services; it does not depend upon your hardware used or your location.  The cloud eliminates the need to store information on your PC, mobile device or gadget with the assumption that the information can be quickly and easily accessed via the net.  There is no need to download or install dedicated software on your own computer which frees up onboard memory thus reducing energy costs.

We already have a lot of people using cloud computing today without realizing it. An excellent example of cloud technology is Google which offers software as a free online service to billions of users across the world. Google hosts a set of online productivity tools and applications in the cloud such as email, word processing, calendars, photo sharing, and website creation tools.
