Research Of Workflow Technology In Cloud Computing Environment

With the development of computer technology and network, the Workflow technology which closely related to the computer network has been development rapidly, propelled by the strong development of the emerging network technology. The emergence of cloud computing have made workflow technology had a great change, how to make traditional workflow technology combine with cloud computing environments, it becomes a hot issue in current research that both retain the advantages of the automated processing of business in the traditional workflow technology, and take full advantage of the unlimited resources of the cloud computing environment.In this thesis, the following topics concerning the researching of workflow technology in Aneka cloud computing environment:(1) In-depth analysis of current workflow technology in the cloud environment. Analyze and summarize the way of workflow build in different levels of cloud environment. Analysis and research on the workflow process in Aneka cloud environment according to the hierarchy.(2) The workflow execution process and workflow architecture on Aneka Cloud environment was given, based on workflow reliability and stability and the characteristics of task execution in Aneka Cloud environment.(3) The process of workflow executes in Aneka cloud is given, it depends on analyzing and researching on the Task Model programming model and the services that provides by Aneka Cloud Environment., so that completes the integration of workflow and cloud computing environments at last.In the stage of experimental, the implementation prototype of the cloud workflow was given. The experiments show that the cloud workflow can take full advantage of the resources of the cloud environment, save the process execution time and cost savings has a good application and development prospects.
