增强云服务可信性的研究

The Research to Enhance the Dependability of Cloud Service

结合自治愈机制与AOP技术,提出了一种增强云服务的可信性框架.该框架从云服务的逻辑实现层面来增加其可信性,以"可插拔"的形式动态配置云服务的可信策略.通过失效注入的方式进行仿真实验,结果表明该框架有效地降低了云服务失效的概率,增强了云服务的可信性.

This paper combines with the self-healing and AOP technology,and proposes a framework to enhance the dependability of cloud services.We consider enhancing the dependability from the logical layer of cloud service and implement ＂pluggable＂ way to configure the dependable strategies dynamically.Using fault injection method for simulation,the result shows that this framework can reduce the possibility of cloud service failure effectively and enhances the dependability of the cloud service.
