Evolution of the cloud computing which are in the virtualization, parallel processing, distributed computing and web based services in between the clients and distributed servers. There are several parameters which are analyzed based on the security, efficiency, performance, adaptability and cost. The main objective of the work is to satisfying the cloud computing users and resources. These conceptual models are discussed from the classic to the contemporary in this paper. Based on these parameters, this methodology is modeled and simulated of a cloud computing using fuzzy logic controller. In this proposed work, the fuzzy logic based cloud computing is implemented to effectively balance the load with high security in between the servers, virtually distributed servers and to the cloud computing users. Keywords: Cloud computing security, Adaptability and Conceptual model for the performance. 1. Introduction Cloud computing has been widely adopted as a means to provide always available, easily scalable computing resources. This has had an enormous impact on the IT industry, changing the way in which computing resources at all levels, including hardware, are designed and purchased. An innovative individual or company no longer requires a large amount of capital in order to deploy or maintain new internet-based services, and provisioning can scale (in cost and computing resources) to meet the demand for their solution. Furthermore, companies requiring timely processing of large amounts of data can buy computing time as needed, rather than maintaining expensive infrastructure that is not fully utilized. Finally, large companies can concentrate on their core business rather than on maintaining an IT infrastructure.
