A Model For Policy-aware Execution of Business Process in Federated Clouds

摘要

Today, Organization's daily operations rely on automatic business processes running on IT infrastructures. On the other hand, fast-changing business environments along with the costly process of in-house development of business process management systems drives the businesses to outsource their business processes. Cloud computing paradigm has become increasingly important for executing business processes as users can exploit the economic and technical advantages of this computing. The Business Process as a Service (BPaaS) paradigm is a new concept in using specific business processes as an intermediary to align business and information technology. The management and deployment of business processes on the existing heterogeneous Cloud providers, however, is still a challenge for the organizations due to interoperability concerns. This paper suggests a Federated BPaaS model, a service aggregation concept characterized by interoperability specifications, to address the integration challenges and the vendor lock-in problem. The analysis and comparison of Policy-Based Approaches shows that our model provides a complete solution for the Process as a Service based on architectural concepts.
