A Cloud Workflow Modeling Framework Using Extended Proclets

Most existing cloud workflow modeling approaches focus on how to support business process customization for multiple tenants. But there are many factors to be considered in actual cloud workflow modeling, such as how to model interaction between different tenants’ business processes while protecting their privacy respectively, and how to facilitate the reuse of common process fragments for different stakeholder roles. To address these issues, this paper proposes a cloud workflow modeling framework using extended proclets. The framework provides a hierarchical management mechanism to isolate the private data of each tenant’s business process and adopts two-level-channel transmission protocol to explicitly model interaction between different tenants’ business processes. At last, a case study is carried out to illustrate its modeling capability
