A Novel Method of Dynamic Cloud Workflow Processing Based on 3D_DWFN

Cloud workflow is the combination of workflow management system and cloud platform. Compared with general workflow system, it can provide optimization of resource management and automatic scheduling of task. However, cloud workflow technology still lacks flexibility and cannot response to the changing business requirements in real time. In order to cope with the changing of business requirements, a dynamic workflow change model 3D-DWFN is proposed. The model is verified to be correct and the migration strategy is set up, thus the dynamic change algorithm is realized. It is applied to a business management system; the experiment shows that it is more effective than general workflow model.
