Software as a service (or SaaS)
Software as a service (or 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, or hosted software. Whatever the name, SaaS applications run
on a SaaS provider’s servers. The provider manages access to the application,
including security, availability, and performance.
