It is obvious that efficient and agile orchestration mechanism for service composition can ensure the scalability and high-efficiency of Web service composition system. Now there are two kinds: centralized and decentralized mechanisms, but in fact, both of two have some defects. On the basis of analyzing them, a service community-based 2-layer orchestration mechanism for dynamic service composition is proposed, which adds a community layer to distribute the control logic and corresponding execution load, Analysis results show that 2-layer mechanism improves scalability and availability and it lessens the unnecessary load and complexity to the system in terms of managing and error recovery and fault handling.
