云计算环境下一种基于资源可用分析的数字图书馆虚拟机部署模型

A Model of Deploying Virtual Machine Based on Analysis of the Resources Utilization for Digital Library Under Cloud Computing Environment

云计算环境下,数字图书馆存在着虚拟机资源分配、虚拟机部署、虚拟机迁移等诸多挑战。文章在分析云计算环境下数字图书馆虚拟机资源利用率和服务可用性的基础上,建立了一种虚拟机部署模型。该虚拟机部署模型改善了云资源的利用率和部署效率,可实现云计算资源的负载均衡和获得较高的资源利用率。

There are many challenges in the virtual machine resource allocation, deployment, migration for digital library under cloud computing environment. This paper raises a model of deploying virtual machine based on analysis of the resources utilization and services availability of virtual machines for digital library under cloud computing environment. The mechanism of deploying virtual machine improves utilization of cloud computing resource and the efficiency of deployment, load balance and higher resource utilization of cloud computing resources can be achieved.
