An Approach to Business Processes Decomposition for Cloud Deployment

Due to safety requirements, certain data or activities of a business process should be kept within the user premises, while others can be allocated to a cloud environment. This paper presents a generic approach to business processes decomposition taking into account the allocation of activities and data. We designed transformations to decompose business processes represented in WS-BPEL into sub-processes to be deployed on the user premise and in the cloud. We demonstrate our approach with a case study from the healthcare domain.
