Secure and Cost Effective Framework for Cloud Computing Based On optimization and Virtualization

Cloud computing is emerging technology in today’s era. Its popularity is because of flexibility, scalability, cost reduction and on-demand service. But there is the demand of security in User-Cloud environment, because of dependency increases on the cloud. Several companies chooses cloud environment for business prospective. So when we choose cloud environment we must think about the security issue, because our data is crucial. I study several research papers in this regards. So in this paper i proposed a security framework which is used for IaaS, PaaS and SaaS by the help of Optimization algorithms. In this paper we first survey and analyzes the research work which concentrates on security and reliability issues, then we consider optimization techniques which is helpful for maintaining the security. So overall i want to introduce security model which is more efficient and reliable.
