In cloud computing, software, resources and other technology are shared over the Internet and available to computer users on demand. A company using cloud computing no longer internally owns and manages its IT systems, but instead contracts with a third-party cloud provider for these services. In short, cloud computing is a form of outsourced IT services. Cloud popularity continues to increase because it has very few up-front costs, does not require purchase or maintenance of significant hardware, and can scale to the need of the company without purchasing new software or hiring new personnel.
