Service and Protection Level Agreements for Business Processes ?

The issue of business process design for a complex web service provision is gaining attention and has been addressed in a number of recent works. We argue that calculation of global quality of service and protection, which then is negotiated with a client as service and protection level agreements, for complex web services must be based on business process. The quality of service in web service compositions plays a vital role and has opened a wide spectrum of challenges. Therefore, the orchestrator should design its business process aggregating web services in such a way as to make it more efficient from the quality of service and protection point of view. In this work we propose a methodology that identifies the concrete business process providing the highest quality of service and protection among all possible design alternatives.
