An Event-Driven Service-Oriented Computing Platform

Abstract

SOA implementations based upon Request/Response model have deficiency in tight-coupled communication and poor cooperativity. Event-Driven Architecture(EDA) is one of the choices for implementing loose coupled communication with minimum delay and for responding rapidly and effectively to changing conditions, especially complex events derived from multiple events. By introducing Event-Driven paradigm into Service-Oriented computing platform, we can achieve loose couple communication and cooperativity. This paper presents a unified event-driven framework with design in delicacy for high-performance SEDA-based event concurrency and event algebra based event stream processing. To improve event stream processing performance, context semantic and corresponding detection algorithm are also presented. Experiment results prove that the framework is adapted to the dynamic large-scale distributed computing environment well and will be used widely due to its loose coupled communication, cooperativity and high-performance event stream processing and complex event processing properties.
