摘要： 针对云平台中资源调度策略过于简单,不能有效适应医疗业务需求的问题,分析不同医疗系统对资源的不同需求,以此为根据提出IB-Choose资源调度策略。基于OpenStack平台构建包含医生诊疗系统、实验科检验系统和影像归档系统的医疗云平台,并在该平台上实现IB-Choose策略。实验结果表明,与OpenStack默认资源调度策略Chance相比,IB-Choose可将启动虚拟机的服务时间缩短25%~30%,同时减少云资源开销并提高其利用率。

Abstract: The resource scheduling policies for the cloud platform are too simple to meet the needs of the medical service effectively.Aiming at this problem,this paper analyzes different demands of different medical systems on resources and proposes the IB-Choose resource scheduling strategy on this basis.It builds a medical cloud platform with doctor diagnosis and treatment system,laboratory test system and image archiving system based on OpenStack platform,and implements the IB-Choose strategy on this platform.Experimental results show that,compared with the default resource scheduling policy in OpenStack,named Chance,the IB-Choose resource scheduling policy can shorten the service time of starting virtual machines by 25%~30%.At the same time,it reduces the cloud resources overhead and improves the utilization rate of cloud resources.
