Simulation-based Evaluation of an Intercloud Service Broker
Foued Jrad, Jie Tao, Achim Streit · 2012
Abstract—The lack of common standards in a fast emerging Cloud computing market over the last years resulted in “vendor lock in ” and interoperability issues across heterogeneous Cloud platforms. Therefore, the Cloud user is facing now a challenging problem of selecting the Cloud provider that fits his needs. A new promising research approach is the use of intermediate broker services to assist the user in finding the appropriate Cloud resources that satisfy his requirements. In this paper, we present a generic simulation framework based on the CloudSim toolkit for the validation and evaluation of a Cloud service broker deployed on an Intercloud environment. A unique feature of the framework is the integration of several state of the art technologies and standards, which makes it easy to deploy on real production Clouds. After presenting the framework fundamental architecture, we discuss in detail the solved implementation challenges. Finally, we present some initial evaluation results.
