摘要：The digital-Era generation is tuned to operate on Multi-mode resources with verity of choices of cloud services to satisfy their customers� requirement. In the past the cloud service providers were very limited to satisfy these multi-mode customers with their inadequate available resources. Hence there is a wide increase on cloud service providers in a federated environment, due to its advantages of multiple reductions in infrastructural cost, service availability, performance and scalability. From the available cloud services, there is a great need of the hour to choose the service provider through the Cloud Broker Architecture. Along with the cloud broker architecture, the cloud service ranking model comes as an aid for an efficient selection of the cloud provider for the requested user. Hence cloud service ranking becomes a process of selecting the best and suitable provider. In this work we base our proposed method of ranking on the Fuzzy logic set. We discuss on different ranking methods and propose a suitable ranking method based on Random variable selection in ranking with the extended parameters like quality of service, cost reduction, performance and response time by the cloud service providers. In the proposed approach, Federated Cloud Architecture (FCA) shortlists the related CSPs for the user tasks automatically and chooses the optimal provider using the concept of preferential ranking mechanism. The solution is arrived by accomplishing the quality of service based SMI attributes which is the measuring parameters form the pool of cloud service provider (CSP)s.
