Software as a Service (SaaS) is a buzzword especially in the realm of Cloud Computing. One can reduce the number of applications deployed on the data-centers by using similar applications hosted by the SaaS providers. Thus, "Reusability" of a SaaS is a key-point of focus promoting the same code-base of an application serving multiple clients. This reduces the need for more storage space and computational power in the data-centers thus aligning the SaaS architecture to a "Greener" computing paradigm.
