Research And Implementation Of Service Management In Enterprise Application Integration Based On ESB

With the continuous development of the application of enterprise SOA, IT system must also be able to meet requirements of business changes. From the business perspective,SOA guides the construction of enterprise IT system, easily to understand business, flexibly to respond to business changes and rapidly to implement the business requirements. And the IT system provides support for management, monitoring and government in business, thereby strengthening the consistency between IT system and the business. System is composed by a loosely coupled business services, they depend on the standard service interface or service description, but these service interfaces are discrete. If there are a large number of discrete, distributed service interface within the enterprise, and these service interfaces have not been effective management, IT and operational staff takes effort to establish point to point connection with a particular service interface, Internal dependencies between the service interface is not able to get display, thus impeding the reuse of services. Therefore, the service management issues in Enterprise Application Integration is increasingly prominent, which is the focus of this research.This thesis presents a more complete Web services management mechanism--, Global Repository, GLR, based on a unified, discovery and integration UDDI3.0 protocol specification, to overcome the deficiencies of their safety and reliable delivery of messages. Through an enterprise-class service metadata database and resource repository, GLR establish a unified Web service management mechanism, used to store, search, publish, subscribe to, and manage enterprise services and resources. Based on GLR, business services and resources can be unified management, and forming a global view of services and resources, while promoting enterprise services and resources reuse. GLR major commitment to ensure SOA business agility by the three aspects: facilitating reuse of services, optimizing the use of services and resources and visualization of services and resources.In this thesis, it takes integrate of order management system and production management system in enterprise application integration as an example, with the help SOA solutions which integrates ESB, BPM and GLR to solve this problem. ESB realizes the original routing services and packaging, BPM orchestrates business process of the entire supply chain, so that integrating the entire business process based on the business process, and the business process are published as Web services as the entrance of the business. Key highlights the use of GLR to achieve the existing service registration and management, the system can quickly adjust to the change of business, fully embodies the SOA loose coupling, demand characteristics, fully embodies advantages of the GLR in enterprise application integration for service management.
