摘要 如何从服务的提供、运营和使用等多个维度有效组织和管理服务是软件即服务(SaaS)模式下面临的一个重要挑战.以支持服务发现为主要目标的传统服务管理方法难以适应SaaS模式下服务的动态有界、关联演化和可控可测等特征及满足服务全生命周期管控的需求.该文结合全国科技信息服务网实际应用,探索了一种支持科技信息资源整合共享与综合利用的"双向"SaaS模式,并提出一种适于该模式下服务管理的服务社区模型.服务社区模型支持服务元建模和业务规范及服务管控策略自主定义,可以使能面向特定业务领域的有界化和有序化服务管理.文中还针对服务管理边界的演化需求讨论了该模型下的服务社区派生机制.最后,以全国科技信息服务网中的科技信息服务运营管理为具体案例,展示并讨论了服务社区模型的使用方法、应用效果和适用范围. How to organize and manage services from the different dimensions of service provision,operation and usage is a big challenge in SaaS(Software as a Service) mode.Traditional service management methods in Web services research domain,which focus on service discovery and service selection,can not satisfy the management requirements of dynamic partitioning,evolving,monitoring and controlling during the whole service lifecycle.This paper proposes a service community model for a bilateral SaaS mode which is abstracted from a real project of the nationwide service network for sharing science and technology information.The service community model can be used to enable business-oriented service management in an ordered,bordered and controlled way through service meta-modeling and self-configuration of business criterion and service monitoring policy.A generating mechanism for the evolution of service community is also discussed.Finally,the paper gives a case study which shows the usage and practicability of the service community model.
