The term Software as a Service first appeared in 2000 and can be defined as a means of providing remote access services to software where software and hardware components are hosted by the SaaS Provider (Torbacki, 2008). Introduced in 1999 by (Bennett et al., 2000) as a future evolution towards an orientation towards services and virtual markets; Specifically regarding the Internet era and its dramatic effect on organizations in terms of producing agile and dynamic systems, it is asserted that software can no longer be produced as a single system but rather as a family of systems . This alludes to SOA which, in its simplest terms, can be considered a "family of systems", in that each service forms a modular representation of the entire system. In the SaaS model, the provider provides security and data isolation for each software application. There are, however, distinct facets of the SaaS model that help determine whether a system is a true implementation, as cited by Patrick Grady, CEO of Rearden. based on a platform, then it's crap and the customer will not benefit from any of the advertised benefits” (Deyo, 2008). Additionally, the system must be accessible via the Internet, using any web browser, for example. FireFox, Opera, Microsoft Internet Explorer and operating platform (Deyo, 2008). The reason it can quantify it so explicitly could be because SaaS is often compared to a similar model called ASP (Application Service Provider). The ASP model simply hosts an application. solutions with a provider but without underlying changes to their systems and hosting infrastructure (Kaplan, 2006).
