云计算环境下数字图书馆虚拟机资源分配及部署策略研究

Study on Virtual Machine Resource Allocation and Deployment Strategy for Digital Library under Cloud Computing Environment

本文首先对云计算环境下数字图书馆虚拟机部署的体系结构和部署流程进行了阐述,然后针对虚拟机资源的分配、部署、迁移以及物理服务器的整合等问题,提出一种云计算平台虚拟机部署机制。该机制能够获得较好的系统负载均衡效果和较高的资源利用率,并且提高了任务的分发部署速度、系统吞叶量和资源利用率,增强了任务的加速比和系统运行效率。

This paper elaborates the architecture and deployment process of virtual machine for digital library under cloud computing environment firstly, and then aiming at the virtual machine resource allocation, deployment, migration and the integration of physical server, etc, presents a virtual machine deployment mechanism on cloud computing platform. The mechanism can achieve better load balancing performance and higher resource utilizatiun, and can improve the speed of tasks distribution, deployment and execution, and the system throughput, the task speedup rate is therefore in creased.
