Research And Design Of High Availability Cloud Platform Based On OpenStack

Over the past decade,Cloud computing as a new technology has caused the third wave of information technology after the personal computer and Internet technology.Cloud computing is designed to for computing,networking,storage and other IT resources for effective integration and on-demand,take according to necessaries that,through the Internet in the form of providing service for the enterprise or individual users.There have been many colleges started by building a private cloud computing platform to improve the utilization rate of server resources in colleges and universities;For college teachers and students to provide flexible application solutions,improve the stability of application system,scalable,and reliability,reduce the college information center server room space and power consumption,reduce the informatization infrastructure construction investment cost;At the same time solve the traditional information center IT resource management complexity,poor scalability,poor stability and so on.In this paper,a solution based on Pacemaker + Corosync + HAProxy + Ceph is presented,and a solution of private cloud computing management platform based on OpenStack cloud operating system and Ceph distributed storage is designed.Using the existing server as an opportunity,combined with the hospital's office and teaching room real needs to build a cloud computing management platform and through two different levels of testing to verify its high availability.The experimental results show that the high availability solution achieves the high availability of the cloud computing maxnagement platform at all levels,and can guarantee a stable and reliable private cloud computing management platform The main research contents are as follows:1.Aiming at Cloud computing for colleges and universities management platform construction,design a kind of based on it cloud operating system combined with Ceph distributed storage of colleges and universities to build private cloud management platform solutions.Integration of the college's computing,network,storage and other hardware and software resources,to provide teachers and students of the virtual machine server and desktop virtualization cloud services,raise the utilization ratio of the server resources.2.Aiming at the high availability of private cloud in colleges and universities,this paper deeply studies the advanced functions such as real-time virtual machine real-time migration and virtual resource dynamic scheduling in cloud computing platform.Studied the Ceph distributed storage solution,and combined with OpenStack's Nova service components to achieve the high availability of computing nodes.This paper presents a high availability solution based on Pacemaker+Corosync+HAProxy + Ceph to realize OpenStack cloud computing management platform to ensure the reliability and stability of cloud computing management platform services.3.Based on it combined with Ceph distributed storage building private cloud of colleges and universities to carry on the base function and high usability testing.Experiments show that the cloud management platform basic functions to achieve the expected goals.The operation of the deployment for a year as a result,the cloud management platform of high availability test proved that the high availability solution is feasible.
