Towards software engineering paradigm for software as a service

The Software as a Service model of Cloud Computing offers economies of scale through the pay per use model; however, it renders the modern software very different from traditional software. Hence, there is a need to adapt Software Engineering approach in a manner that will make the development process and delivery of Software as a Service more efficient and of high quality. After performing literature review, a classification of ongoing research in this direction of adaptation is presented. Various research gaps in the areas of software development process, software reengineering, measurement, metrics, and quality models targeted at Software as a Service are identified, which can be a first step towards the definition of standards and guidelines for Software as a Service development.
