基于云计算技术来搭建高校计算机实验室已成为目前的一个趋势,它能够节约投资成本,加快实验内容建设。但现有的相关产品一般都基于开源云计算平台构建,如OpenStack,这种方式存在着存储性能不高,虚拟机创建、迁移时间较长等问题。为此,本文设计了基于FUSE的分布式文件系统,并将其引入云计算平台以构建实验室虚拟主机管理平台。该系统将虚拟机镜像和实例分别存储到不同的目标位置,并对共享节点进行多副本存储,从而实现了更加灵活、高效且安全的存储管理。
It is a current trend to set up a university computer laboratory based on cloud computing technology, which can save investment cost and speed up construction of experiment contents. However, the existing related products are generally based on the open source cloud computing platform, such as OpenStack, which has problems of low storage performance, creation of virtual machines, and long migration time. To this end, this paper designed a distributed file system based on FUSE, and introduced it into the cloud computing platform to build a laboratory virtual host management platform. The system stores virtual machine images and instances separately at different destination locations and multiple copies of shared nodes for more flexible, efficient, and secure storage management.
