基于证据推理的云计算服务适应性评估

Adaption assessment for cloud computing service based on evidence theory

针对云计算服务模式尽管对中小型企业吸引力巨大,但由于受到安全、技术、管理等方面的限制并不是都能适用,企业需要根据自身实际需要作出判断的问题,提出了一个云计算服务适应性评估指标体系。该体系从安全与风险、数据、服务、资源、经济五个维度来分析云计算服务的适应性问题,并利用证据推理方法对实际问题进行建模分析,验证了评估指标体系的有效性与合理性。

Cloud computing service model is very attractive to small and medium-sized enterprises,however whether its service capabilities can meet the actual business needs or not is difficult to measure.Based on this,this paper proposed a cloud computing service adaptability evaluation system,from security and risk,data,services,resources,economic dimensions,to analyze the adaptability of the cloud computing services,and designed a numerical example to assess and verified the validity and rationality of the evaluation index system with evidence theory.
