A dynamic qos aware cloud service composition based on multiple cloud environment

Abstract

Service-Oriented Computing (SOC) is a multi-disciplinary area that provides different ways in which the software applications are built, deployed and used. The domain cloud computing provides the requested services to the users-based pay-as-you go model. The major goal of cloud computing is to share resources, which consist of infrastructure, platform, software, and business process. When those resources are provisioned as services, the value of cloud computing is realized. The cloud computing environment is dynamic which faces undergoes many changes during any type of processing. A composite service is obtained from a pool of services where each of the services are selected based on the user s requirement of Quality of Service (QoS) attributes distinct to each service composition. Moreover, the service composition process with an optimal QoS attribute value satisfies the requirements of a customer in a dynamic environment is a complex and challenging issue. In organizations worldwide, composing services from multiple clouds has been one of the greatest challenges. newline
