SCW+: A service-oriented framework for cloud work ow systems

Cloud work ow is a special type of cloud computing systems which mainly concentrates on work ow management. One of the major issues with cloud work ow systems is automatic multi-cloud work ow management. This paper proposes a service oriented framework for cloud work ow management which integrates heterogeneous multicloud platforms to provide integrated applications for users by minimizing the human intervention as far as possible. The proposed framework involves a language to dene some basic entities for environments and uses these denitions to integrate applications and services in a cloud work ow. This framework has already been implemented. In addition, its main operations have been evaluated by a case study and the results show that the framework works properly as a cloud integrator and main activities of the framework are done automatically with a reasonable performance.
