Message-Oriented Middleware (MOM) is an enterprise middleware technology, which is designed to solve the communication and queuing problems in heterogeneous distributed system. ActiveMQ is a cross-platform and cross-language implement ation of MOM. Firstly, this paper introduces its features and makes a back-to-back testing in stability and performance. Then, a bus controller module is added to it and the common asynchronous message bus is built. It is proved that the message bus can improve the development efficiency and processing performance of mobile value-added business.
