  • You do not need expensive hard drive to store your data.

  • You do not need expensive servers, computers and other hardware in order to access computing power.

  • Cloud computing reduces maintenance.

  • Workers in a given company can use software and applications in the cloud computing system without having to pay for each one. Instead the company pays some fees the cloud computing company for the service offered.

  • Due to the architecture of cloud computing systems, which includes networked computers, large processing computer power is provided when needed.

4) How to use cloud computing?
