摘要 云计算环境的复杂性、动态性和开放性特征,使得云计算系统的规模和结构日益复杂,产生的故障越来越多.现有的动态故障模型只关注于故障及故障间的关联关系,忽略了对故障特征的分析与处理,未动态关联故障与故障特征.因此,本文提出了一种云计算环境下服务故障模型动态建立方法.首先,预处理服务运行数据;其次,从预处理后的服务运行数据集中抽取服务故障与服务故障特征;最后,动态关联服务故障与服务故障特征,实现云计算环境下服务故障模型的动态演化.本文基于提出的云计算环境下服务故障模型动态建立的方法进行了相关实验,验证了方法的有效性. The complexity,dynamics and openness of the cloud computing environment make the scale and structure of the cloud computing system increasingly complex,resultingin more and more faults.The existing dynamic fault models only focus on the faults and the correlation between them,the analysis and processing of the fault characteristics are ignored,and do not dynamically correlate the faults and the fault characteristics.Therefore,in this paper,a method for dynamically establishing a service failure model in a cloud computing environment is proposed.Firstly,preprocessing the service operation data.Secondly,the service failure and service failure characteristics are extracted from the preprocessed service operation data set.Finally,dynamically correlate the service failure with service failure characteristics to realize the dynamic evolution of the service failure model in the cloud computing environment.Based on the proposed method of dynamic establishment of service failure model in cloud computing environment,the related experiments are carried out,and the effectiveness of the method is verified.
