面向应用服务的虚拟机性能评估

摘要

In cloud ,lots of VMs are running to provide the application service .To get the VMs’ specific load characteristics , which can be used to identify the behaviors of the application service ,a collection method was designed to collect the VMs’ load information and make it more effective to achieve the VMs’ state information .A design of performance evaluation algorithm was presented based on the specific application service type .First ,the VMs’ system information was collected to calculate the VMs’ basic characters ,then the VMs’ performance load was quantified .The method gives a new solution on how to use resources of VMs and PMs adequately .%为了获取在云平台下提供应用服务的虚拟机所表征出的特定负载特性（这种负载特性可以用来标识此应用服务的行为），设计对现有虚拟机负载信息进行采集，达到了对虚拟机状态信息和负载信息有效获取；通过获取到的虚拟机系统信息，提出基于指定类型优化的性能评估算法，得出虚拟机的基本特征，对虚拟机性能负载进行量化。为虚拟机资源和物理机资源的充分使用提供解决思路。
