On-premises software

On-premises software (sometimes abbreviated as "on-prem" or stated incorrectly as "on-premise") is installed and runs on computers on the premises (in the building) of the person or organization using the software, rather than at a remote facility, such as at a server farm or cloud - somewhere on the Internet. On-premises software is sometimes referred to as “shrinkwrap” software, and off-premises software is commonly called “software as a service” ("SaaS") or “computing in the cloud”. There is some debate[1][2] as to the validity of the longer-used[3] term "on-premise" compared to its grammatically correct synonym "on-premises", despite its now-commonplace use among technology companies and technology news sources.[4]

The on-premises approach to deploying and using business software was the most common until around 2005, when software running at a remote location became widely available and adopted.[citation needed] The new, alternative deployment and use model typically uses the Internet to remove the need for the user to install any software on premises and had other accompanying benefits: running software remotely can result in considerable cost savings because of reduced staffing, maintenance, power consumption, and other factors.
