Abstract:
Cloud environments are being increasingly used for deploying and executing workflow composed from cloud services. In this paper, we propose a meta-model transformation for the specification and the execution of cloud service flexible workflows. To built workflow abstract models, the proposed approach uses a BPMN model for the specification of the cloud service workflow structure and the state-chart diagram for the specification of the cloud service workflow behavior. In addition, workflow models should be translated into BPEL4WS language which will be executed by the BPEL4WS engine, the latter is driven by the behavior described by the state-chart diagram. To fulfill, we define a set of meta-model transformations from the platform independent model (BPMN) to the platform specific model (BPEL4WS).
