Research And Application Of Enterprise Service Bus Based On Service Oriented Architecture

With the quickly development of economic globalization and information technology, the enterprises have accumulated lots of information systems. These systems are usually independent, heterogeneous and isolated. They can not share information and resource. So the enterprises need a flexible and effective application integration approach urgently to manage all its information systems, thus to improve its management efficiency of its daily running.Currently, the most popular solution of Enterprise Application Integration (EAI) technology is to construct a Service Oriented Architecture (SOA) based on Web Service technology. Enterprise Service Bus (ESB) is the most important infrastructure of SOA. Implementing SOA using ESB can impose all the advantages and values of SOA completely.This article has researched the basic theories and interrelated technologies of SOA in depth and focused on the theories and implementation of ESB. Current ESB products are mainly based on Message Middleware technology, and have not analyzed all the requirements of ESB. It restricts the availability and scalability of ESB, and can not meet the enterprise's highly concurrent request and real-time response requirements. This article firstly bring forward a new architecture model for ESB based on Plug-In technology, and then discuss some key technologies including requests capture, requests dispatch, real-time response etc. At last, ESB is proved to be feasible and effective by prototype system's application in practical projects.
