Abstract—The paper firstly analyzes the characteristic of existing workflow applications and proposes cloud workflow layered model and design method based on the current major cloud computing trends. Considering the features on the cloud workflow system in distributed heterogeneous environment, the paper proposes a brief introduction to approach to cloud workflow system. Next, three deployment models of the cloud workflow applications are presented. Finally, the paper presents a new dynamic scheduling algorithm –Improved Dynamic Cloud Scheduling Algorithm(IDCSA) which takes consideration of the characteristics of cloud workflow and cloud resources.

Index Terms—Cloud workflow; layered model; style; distributed heterogeneous environment; deployment models; IDCSA.
