云计算平台虚拟机调度策略研究 摘要 虚拟化是云计算平台资源能够灵活分配的基础，虚拟机资源分配和调度策略是影响用户体验与云平台性能的主要瓶颈。传统的随机分配与轮询调度方式存在资源负载失衡、调度延时、扩展困难等问题。本文考虑负载均衡、资源利用、用户体验、优化配置、高可靠性等，分别研究了集中式云平台与多域分布式云平台的虚拟机分配和资源调度策略。 针对 IaaS 模式下的云计算平台进行了调研分析。首先对云计算平台进行了详细介绍，特别是 IaaS 模式的云计算平台的相关知识进行重点介绍。在此基础上介绍了 IaaS 资源调度的相关理论和技术，其次是分析了当前 IaaS 模式云平台的资源管理技术现状与使用的虚拟机调度算法，然后对本文研究工作所要用到的基本理论进行介绍，主要包括具体的负载均衡理念和系统中使用到的一致性哈希算法。 关键字：云平台， 虚拟机调度， 集中式调度， 分布式调度 ABSTRACT Virtualization is the basis for flexible allocation of cloud computing platform resources. Virtual machine resource allocation and scheduling strategy is the main bottleneck affecting the user experience and cloud platform performance. Traditional random allocation and polling scheduling methods have some problems, such as resource load imbalance, scheduling delay, and expansion difficulties. Considering the load balancing, resource utilization, user experience, optimized configuration, and high reliability, this paper studies the virtual machine allocation and resource scheduling strategy of centralized cloud platform and multi domain distributed cloud platform. For the IaaS mode of cloud computing platform to carry out the investigation and analysis. First of all, the cloud computing platform is introduced in detail, especially the IaaS model of cloud computing platform related knowledge is introduced. On the basis of the IaaS theory is introduced and the resource scheduling technology, the second is the analysis of the virtual machine scheduling algorithm using resource management technology status and the current IaaS mode of cloud platform, and then the basic theory of the research work in this paper will use are introduced, including the consistent hashing algorithm to use the balanced idea and concrete system load in.
