摘　　要：在研究了应用SOA整合SaaS模式下云服务可行性的基础上,基于SCA提出了一种侧重服务组件可变性的封装结构——VSCA,运用形式化描述机制抽象出固定性和可变性。针对以SCA粒度划分的配置模型缺乏对多租户可变特征的支持,在多租户单实例模式下,提出了一种基于VSCA的多租户功能可配置层次模型。在可变性建模过程中,该模型满足租户在共享基础实例的同时实现自定义配置,满足了多租户的个性化需求。通过表述可变性在具体实现过程中的扩展方法以及应用具体实例,验证了该模型的灵活性和有效性。After studying the feasibility of using SOA integrated cloud services in SaaS mode,based on SCA,a package structure,namely VSCA,was presented,which emphasized on variability of service component and used a formal description mechanism to abstract fixity and variability.Using SCA granularity to divide configuration model could not support the variability of multi-tenant.In multi-tenant single instance mode,a configurable hierarchical model of multi-tenant function based on VSCA is proposed.In the variability modeling process,the model was able to support tenants to share instances,at the same time it realized the custom＇s configuration to meet the individual need of multi-tenant.In the concrete realization process,by illustrating the extension methods of variability and using a multi-tenant application,the flexibility and the validity of the model was proved.
