基于OpenStack的数字校园体系架构研究

当前,云计算技术的广泛应用已成为不可阻挡的趋势,随之而来的开源云计算也迅速崛起。开源云计算以其开源性、低成本等优点吸引越来越多的用户。对开源云计算OpenStack的功能和架构进行介绍,并针对高校数字校园存在的问题,从数字校园的实际需求出发,利用先进的OpenStack平台,采用分层设计的方法设计、实现一个可对云资源进行综合管理的数字校园体系架构。并重点研究该架构中的资源调度,提出了一种基于任务调度和负载均衡的方案,通过实践,验证了该调度方案能够均衡服务器的资源负载,使基于OpenStack的数字校园处于相对稳定的状态。

A Study on Digital Campus Architecture Based on OpenStack

At present,the extensive use of cloud computing technologies have become an irresistible trend,alongside with the rapid rise of open source cloud computing. Open source cloud computing is attracting more and more users due to its low cost and open source. This paper explains the function and architecture of OpenStack. Based on the current problems and the actual demands of digital campus and followed by utilizing the advanced OpenStack platform,the paper adopted hierarchical design method to achieve the architecture of digital campus that could be used to perform integrated management on cloud resources.It focused on resource scheduling in this framework and proposed a scheme that based on task scheduling and load balancing.The experiment of the scheme verifies that the scheduling strategy can balance server＇s resource load,so as to make the digital campus based on OpenStack relatively stable.
