SCW+: A service-oriented framework for cloud workow systems

Cloud workow is a special type of cloud computing systems which mainly concentrates on workow management. one of the major issues with cloud workow systems is automatic multi-cloud workow management. this paper proposes a service oriented framework for cloud workow 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 define some basic entities for environments and uses these definitions to integrate applications and services in a cloud workow. 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.
