Evaluating Paas Scalability and Improving Performance Using Scalability Improvement Systems

Cloud computing has almost changed the way of obtaining resources and managing platform as a service. With these improvements, challenges like scalability testing, performance testing is emerging very fast. This paper focuses on the evaluation of scalability of PaaS as well along with that propose a graphical model where SIS (Scalability Improvement System)is proposed in which cache are implemented at the both interfaces of PaaS to enhance the scalability in terms of providing service to the user.
