An Analytical Approach to Mitigate DDoS Attacks and Improve Network Performance under Collaborative Software as a Service (SaaS) Cloud Computing Environment

Cloud Computing is a latest buzzword now a day’s , emerges as a key service of the Utility computing which builds on decade of research in the field of networking, web and software services. It offers a service oriented architecture, reduced information technology overhead for the end-user, great flexibility and reduced total cost of ownership but recent attacks on the clouds specially DDoS poses as a potential threat to this key technology of the future. In this paper we are going to present an Analytical approach to mitigate the DDoS attack which further improve network performance in terms of computation time under Software as a Service (SaaS) Cloud Computing environment.
