在运用Web服务之前,因缺乏标准和“松散耦合”的策略,合作伙伴间的系统整合受到严重限制。随着使用Web服务和SOA来整合合作伙伴,人们会发现,IT系统在使用业务合作伙伴系统所提供的功能中,已经开始依赖于这些功能的可用性。因而,用户开始从内部管理自己服务的可用性转向要求监视和管理(可能有许多)企业之间的可用性。这大大增加了管理IT系统的复杂性,但它也带来了巨大的价值,这就是为什么许多企业要转到这个方向的原因。
Prior to using Web services, system integration between partners was severely constrained by the lack of standards and loosely coupled tactics. With the consolidation of partners using Web services and SOA, one finds that IT systems have begun to rely on the availability of these features in the capabilities provided by the business partner system. As a result, users are beginning to shift their focus from managing the availability of their services internally to requiring the monitoring and management of (and potentially many) enterprises. This adds significantly to the complexity of managing IT systems, but it also brings tremendous value, which is why many businesses are going in this direction.
