面向服务架构(service oriented architecture,SOA)适用于分布式企业信息系统的跨域集成方案,但其现行的实现方法很难同时较好地实现系统的高度安全性和服务流程编排的松耦合性。为此提出了一种服务访问代理方法,基于SOA建立了一套服务访问代理系统(service access agentsystem,SAAS),对分布式企业服务总线上的服务资源进行共享管理和访问控制。该方法能够有效保障互联网上跨域集成的安全性,并在此基础上显著改善流程编排的敏捷性和可维护性。在某集团型企业信息化建设中,本方法显示了良好的应用价值。
Service oriented architecture (SOA) is a cross-domain integration solution for distributed enterprise information systems. However, its current implementation method is hard to achieve both the high degree of system security and the loose coupling of service process orchestration. Therefore, a service access agent method is proposed. Based on SOA, a set of service access agentsystem (SAAS) is established to share and manage the service resources on the distributed enterprise service bus. This method can effectively guarantee the cross-domain integration security on the Internet, and on the basis of which, the agility and maintainability of process orchestration can be significantly improved. In a group of enterprise information construction, the method shows a good value.
