A Qos Aware Dynamic Service Composition in Cloud Environment

Service composition provides aggregation of services by composing various basic web services. The web service composition is difficult to get fit to dynamic business applications. Cloud computing, an efficient way to manage and integrate on demand computational resources is a new way to solve this problem. This paper describes the process of composition of dynamic services in a cloud environment, by considering the Flight Baggage Service as an example. To address this issue, an agent based service composition method is proposed for optimal solution. Cloud participants and service providers are implemented and instantiated by agent for flight baggage service application. However, a cloud service has various QOS (quality of service) information for providing the best service to the end user. In organizations worldwide, cross cloud has been one of the greatest challenges. By implementing cross cloud, common managing environment for public and private clouds enable customers to connect, run, manage and secure the applications. Applications that run on different cloud computing platforms are composed and the theoretical, experimental results are compared to evaluate the efficiency achieved.
