摘要
由于应用服务受到复杂的组件、配置和部署条件等多维因素的影响,在实际的云计算数据中心配置不同参数进行测试分析是不现实的.因此使用模拟工具合理有效的进行资源和任务的调度分配策略仿真实验就尤为重要.基于此,本文介绍了三种主流云计算仿真平台,分别是:Cloud Sim、Cloud Analyst、Cloud Reports,对其各自的特点进行了分析比较,通过常用的任务调度策略分别对三种仿真平台进行了仿真实验,对其性能进行评估分析,并针对其存在的缺陷进行了改进和优化.
It is unrealistic to configure the different parameters and test analysis in a real cloud computing data centers. Because of the multi-dimensional factors such as the application service are effected from the complexity components, configuration, and deployment; it is most important to use Simulation tools to effective for resources and task scheduling strategy simulation experiment. Based on these, we introduce three major cloud computing simulation platform in this paper： Cloud Sim, Cloud Analyst, Cloud Reports, analysis and comparion on the characteristics of its own, separately proceed the three kinds of simulation experiment of simulation platform by the usual task scheduling strategy, evaluates and analyzes its performance. The existing defects are improved and optimized.
