Complex workflow tasks need in some cases to be mapped to distributed resources and involves the cooperation between several partners. Workflow management is critical to a successful long-term cloud computing strategy. The notion of inter-organizational workflow still needs conceptual and technical support especially in complex and dynamic environments like clouds. In this paper, the authors present an architecture for enabling complex workflow execution in cloud-like environments. They focus mainly on modeling concepts and techniques to enhance accessibility to cloud services by different kind of users.
