Abstract

As composite services are often long-running, loosely coupled, and cross application and administrative boundaries, they are susceptible to a wide variety of failures. This paper presents a solution for fault-tolerant web services orchestration by using relaxed atomic execution and exception handling. To achieve atomic execution, a scalable commit protocol is proposed, which allows heterogeneous transactional web services to participate in a composition. A recovery algorithm is given to ensure a reliable service orchestration in the presence of failures.
