Data transfer performance of web service workflows in the cloud environment

Abstract

Web Service Data Forwarding (WSDF) is a framework for centralized web service workflow, in which the intermediate result from a previous service is treated as a resource of the composite service and can be directly used by its subsequent service, without sending back to the centralized control centre. We carried out a test of the WSDF framework within a web service workflow, in which the service providers are located in the ScienceCloud, provided by the Nimbus cloud infrastructure. The experiment shows that, in the cloud environment, the WSDF framework has significant performance advantage over normal web service framework for workflows with large data transfer.
