基于 Op enst ack 的科研教学云计算平台的构建与运用

摘要

With the rapid development of cloud computing technique ,the cloud computing has some advantages of high utility ratio .Comparied with general function of construction of university computing resource in education and science ,the cloud computing ,which provides high security ,high elastic recource allocation and lower hardware requirements ,can satisfy quickly resource construction for every field .Based on Openstack open source community ,an educational cloud computing platform has been constructed ,which is particularly suitable for scientific researh and teaching .It allocates elastic resources flexibly for labs ,meeting different needs from education ,programming ,testing to management ,also ,it's a practical platform for searching clusters ,distributed computing ,cloud computing applications ,etc .%随着云计算技术的发展与运用，云计算在资源的效用比、按需服务等方面优势显著。相对于高校传统的计算资源构建，云计算凭借其安全性保障、高效的弹性计算资源分配能力、简易的硬件要求等特性，能实现面对不同需求时的计算资源快速弹性构建。基于Openstack开源云计算平台，构建了一个适用于高校教学和科研实验的校园云计算平台，既能弹性分配实验计算资源，满足课程教学、开发、测试、管理等不同需求，又成为集群技术、分布式计算、云计算应用等研发工作的实用平台。
