On-premises software (often abbreviated as on-prem software, and also often incorrectly called “on-premise”
software) is installed and run on computers on the premises (in the building) of the person or organisation 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” or “computing
in the cloud”.

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

cost savings because of reduced staffing, maintenance, power consumption, and other factors.
