Modeling And Design Of Digital Campus Based On OpenStack Cloud Platform

“Cloud computing” is very popular in recent years,its meaning has already crossed the academic and technology,expand to financial institutions as well as schools and government.OpenStack is one of the “Cloud Computing”that can perfectly implement “cloud”,and its codes are open.How to make the digital campus construction to adapt to the trend of the "cloud" in the ever-changing science and technology development not as backward,is concerned as the need of the development for modern university.And also the problem that professional and technical personnel of colleges and universities should research.Implemented the deployment of digital campus in “Cloud”,integrate the original school equipment,cost savings for the school,bring convenience for teachers and students,better service for managers is the pursued goals for each IT personnel of colleges and universities.This paper is the use of open source cloud operating system to build the cloud computing platform integrated environment,used in constructing a good cluster deployment for software companies to develop the digital campus application system,using cloud platform for resource scheduling,so as to provide reference for digital campus builders.Firstly,studied and researched Openstack architecture in depth;analyzed the five parts;master the structure,principle and characteristics.Secondly,deployed a three-node Openstack fully distributed cluster as the deployment of digital campus service resource pool.Thirdly,detailed the design idea about OpenStack cloud platform to build digital campus,architecture,construction model,and made detail analysis of the cloud computing infrastructure as a service;platform as a service;software as a service three service modes of digital campus deployment.Fourthly,the results are verified through the experiment.The results show that OpenStack clusters in the face of a large number of data processing,its powerful computing and storage capacity is obvious,resource management and scheduling are more convenient,this also verified that using OpenStack cloud operating system to set up campus cloud deployment of digital campus construction is a very good move.
