Integrating SaaS and SaaP with Dew Computing

Software as a Service (SaaS) is one of the major service models of cloud computing and a new software delivery model, in this software delivery model, software is hosted centrally, is licensed to users on subscription basis, and typically is accessed by users through a Web browser. Before SaaS was introduced, the traditional software delivery model was Software as a Product (SaaP): software was sold to users and installed in users local computers. In this paper, we discuss the advantages and disadvantages of SaaS and SaaP, and suggest a new software delivery model that is an integration of SaaS and SaaP. Dew computing can be used to integrate SaaS and SaaP. This new software delivery model has some great features.
