Cloud computing refers to the growing practice of selling IT as a service that is delivered over the Internet. The most common forms of cloud computing include Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS). Software as a Service (SaaS) is widely used by Internet users in the United States, such as to access web-based email or to share documents online. Users can access these applications online through a web browser on a PC or mobile device, rather than through software installed and run on a local desktop or server.
