服务网格中面向业务用户的服务组合方法

A Business Users-Oriented Service Composition Approach in Service Grid

服务网格环境中如何快速构建组合服务,为业务用户提供快速整合资源、配置集成化应用的平台,按需创建个性化应用,以降低大规模软件开发的成本、提高效率,成为了服务网格领域亟待解决的一个问题。提出了一种服务网格环境中面向业务用户的服务组合方法,它通过服务映射机制实现从业务用户所熟悉的业务服务到具体物理服务的映射;利用基于上下文的流程推导技术实现了组合业务服务流程向组合物理服务流程的映射;利用物理服务选取技术,生成能够最大限度满足用户需要的组合服务。研究表明该方法应用的原型系统,适用于普通业务用户,能够提高组合物理服务流程构建的效率。

How to establish composite service within the service grid environment in a just - in - time manner and allow business users to configure their applications through easy operations becomes a hot issue in the research area of grid computing. This paper proposes a business users - oriented service composition approach which implements the mapping between Services through 3 - level mappings in order to form the relation between user- familiar business services and physical services, implements the formalization from composite business service process to composite physical service process through context - aware computing techniques and through service selection makes the composite physical service meets users＇ requirements. The research shows that the prototype system of this approach is used well by normal business users which can also improve the effectiveness of formalization of Composite service.
