A Literature Survey in Cloud Access Control Using Novel Optimization Algorithm

Cloud computing is a recent and modern technique of computing in which dynamically scalable and other virtualized resources are provided as a service over the Internet. The energy consumption and make span associated with the resources allocated should be taken into account. This paper proposes an improved optimization algorithm based on time cost and energy consumption models in cloud computing environment. We have analyzed the performance of our approach and investigational results show that our approach has immense potential as it offers significant improvement in the aspects of response time and makespan, demonstrates high potential for the improvement in energy efficiency of the data center, and can effectively meet the service level agreement requested by the users. This paper describes the cloud service architecture and key technologies for optimization algorithm. Cloud computing is a hot topic on software and distributed computing based on Internet, which means users can access storages and applications from remote servers by web browsers or other fixed or mobile terminals. Because the constrained resources of fixed or mobile terminals, cloud computing will provide terminals with powerful complementation resources to acquire complicated services. The paper discusses the cloud service architecture, access control and optimization algorithms about service selection with adaptive performances and minimum cost. The cloud service architecture is reasonable and the proposed optimization algorithms are available, scalable, and adaptive to different types of environments of services and clients.
