SaaS vs. SaaP: The Difference Between Owning and Leasing

One of the more interesting developments in enterprise technology is the emergence of “software as a service” (SaaS) as a viable alternative to the conventional concept of “software as a product” (SaaP). The SaaP philosophy is one most readers should already be familiar with: when you purchase software, be it Microsoft Office or Super Mario Bros., it’s theoretically yours for life. SaaP programs are paid for at the point of purchase and subsequently installed on or run from your own computers, servers, or other on-premise hardware. While most vendors offer a separate technical support agreement for purchase, providing access to updates, bug fixes, and other support, generally once you buy a SaaP solution the responsibility is on you and your IT department to ensure it runs smoothly.
