Performance Evaluation Of SOA In Clouds

An approach for constructing an Enterprise Service Bus based Service Oriented Architecture for individual clouds and then considering workflows where services from multiple clouds are used is formulated and a systematic methodology for performance evaluation of the architecture is presented. The participation in this environment is achieved by allowing the SOA to dynamically federate with services through Community of Interest registries, i.e., different clouds, and by utilizing these services to share enterprise-level information. The performance prediction methodology is based on multiformalism modeling.
