Abstract—It is possible to utilize cloud computing to address the problems of resource extendibility and flexibility for managing large scale workflow applications. Therefore, the investigation of workflow systems based on cloud computing, namely cloud workflow systems is a timely issue and worthwhile for increasing efforts. The technology and application of workflow in cloud computing environment also becomes a research focus. The paper firstly proposes a brief introduction to the cloud workflow system. Next, based on cloud architecture, the paper presents the architecture of cloud workflow system. Then, as the key content of the paper, considering the service selection strategy based on constraint, the paper presents a new service selection algorithm–SSAC. The simulation results show that SSAC algorithm further decreases the total execution cost and total execution time in comparison with other algorithms.
Index Terms—Cloud workflow system; service selection strategy based on constraint; SSAC.
