Daniel Franz, Jie Tao, Holger Marten, Achim Streit · 2011
Abstract—This work developed a workflow engine that enables the execution of workflows on existing Cloud platforms. The workflow engine automatically delivers the computation of each individual task to the selected Cloud and transfers the input/output data across different platforms. Additionally, it predicts the execution time and payment of the tasks, helping users select the best Cloud services with respect to the performance vs. cost tradeoff.
