IaaS环境中一种保证SLA的资源调度策略
Resource Scheduling Strategy for Guaranteeing SLA in IaaS Environment
摘要
Abstract
When Infrastructure as a Service(laaS) cloud computing center's resources need to be reallocated for some reason,Minimization of Migrations(MM) strategy has more migrations when choosing migration set in processing live migration.It increases the violation probability of Service Level Agreement(SLA) and generates a lot of useless energy consumption.Considering this problem,it proposes a modified strategy Find-Migration-Search(FMS).Through the history data of services,it can get the status of each virtual machine.Then the program scans each physical machine with two phase.CloudSim simulation results indicate that the modified strategy FMS can not only lower the times of virtual machines' migration and energy consumption,but also satisfy services' SLA much better,and implements resources optimization deployment under IaaS model.关键词
