Cloud workflow is a special type of cloud computing systems which mainly concentrates on workflow management. One of the major issues with cloud workflow systems is automatic multi-cloud workflow management. This paper proposes a service oriented framework for cloud workflow management which integrates heterogeneous multi-cloud platforms to provide integrated applications for users by minimizing the human intervention as far as possible. The proposed framework involves a language to define some basic entities for environments and uses these definitions to integrate applications and services in a cloud workflow. This framework has been already 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 the framework main activities are done automatically with a reasonable performance.
