What Is SaaS (Software as a Service)?


Chalkboard icon

SaaS (short for Software as a Service) describes when users 'rent' or borrow online software instead of actually purchasing and installing it on their own computers.

It is the same situation as people using Gmail or Yahoo mail services, except that SaaS goes much further. Supadu is a SaaS platform.

SaaS is the foundational idea behind centralized computing: entire businesses and thousands of employees will run their computer tools as online rented products. All of the processing work and file saving will be done on the Internet, with users accessing their tools and files using a web browser.

SaaS, when combined with PaaS (hardware Platform as a Service), forms what is termed 'Cloud Computing'.

SaaS and PaaS describe the business model of users logging into a centralized hub to access their software products. Users open their files and software only while online, using only their web browser and passwords. It is a resurgence of the 1950's and 1960's mainframe model, but tailored to web browsers and Internet standards.

Benefits of SaaS/Cloud Computing:

The primary benefit of Software as a Service is reduced cost for everyone involved. Software vendors do not have to spend thousands of hours supporting users over the phone... they would simply maintain and repair a single central copy of the product online. Conversely, users wouldn't have to shell out the large up-front costs of fully purchasing word processing, spreadsheet, or other end user products. Users would instead pay nominal rental fees to access the large cntral copy.
