Software as a Service

Software as a Service provides users with access to software that is installed on a network and does not need to be installed locally. Like Platform as a Service (PaaS) or Infrastructure as a Service (IaaS), Software as a Service (SaaS) is a subdomain of cloud computing. The software is operated on the premises of an external provider. Users require an Internet connection and a local computer client. In many cases, the software can be called up and run directly via the web browser. Software as a Service is not based on the traditional licensing model that allows users to purchase software along with the right of use. As the service recipient no longer needs to operate the software himself, a usage-dependent or time-dependent licensing model generally applies.
