在传统的客户/服务器（C/S）体系结构中,客户端通过单一通道获取服务器提供的服务,无法实现容灾抗毁,存在服务单点故障、系统扩展能力差等问题,因而传统的客户/服务器结构不能满足高可用环境使用要求。针对高可用服务体系关键性要求,提出了一种基于多服务提供者的高可用服务体系结构,阐述了该服务体系的组成、请求处理流程及服务提供者选择策略等,分析了通过多个服务提供者实现高可用性服务的可行性。

The Client obtains the service from the servers via unique channel in traditional C/S architecture,this could hardly realize the disaster-tolerant recovery,and for the existence of single-point failure and low expansibility,thus the traditional C/S architecture could not satisfy the requirement of the high-availability environment. Based on the key requirements of service architecture with high availability,a service architecture with high availability is proposed. The composition of this architecture,the process of the response flow and the choosing policy of the provider are described in detail. In addition,the feasibility for implementing the service with high availability is analyzed.
