Software as Service Cloud

Software as a Service (SaaS) has the potential to transform the way information-technology (IT) departments relate to and even think about their role as providers of computing services to the rest of the enterprise. The emergence of SaaS as an effective software-delivery mechanism creates an opportunity for IT departments to change their focus from deploying and supporting applications to managing the services that those applications provide. A successful service centric IT, in turn, directly produces more value for the business by providing services that draw from both internal and external sources and align closely with business goals. Despite the promised benefits of cloud computing and software as a service (SaaS) -- greater flexibility and scalability, infrastructure cost avoidance, "anywhere access" to applications and data -- concerns about security and governance have made some organizations hesitant to turn over a chunk of their IT systems to a third-party service provider.
