What is Cloud Computing or Software as a Service?
Cloud computing or Software as a service (SaaS) is a way of delivering applications over the Internet, as a service. Instead of installing and maintaining software, you simply access it via the Internet, freeing yourself from complex software and hardware management. SaaS applications are sometimes called Web-based software, on-demand software, hosted software or software in the cloud. Whatever the name, SaaS applications run on a SaaS provider’s servers. The provider manages access to the application, including security, availability, and performance.
