The Design And Realization Of Maintenance Information Center Cloud Platform Based On The Openstack

After the new computing model is proposed, cloud computing not only speeds upthe deployment of the application and has the significant reduction in the purchase ofhardware, electricity and maintenance costs, but also meet the the business growingdemand for the rapid development and service applications. Information center whichprovides background support for the maintenance system terminal, is composed of a lotof backend servers, switches and routers and other hardware devices. The feature ofheterogeneous equipment and hardware failure brings not only maintainance systeminformation center managers a huge amount of work, but also can not guarantees thenormal operation of the maintenance system when the business system needs to beupgraded. The cloud computing platform can be effective to integrate repair informationcenter underlying hardware resources into a unified platform to improve serverutilization efficiency, reduce maintenance informationcenter managers workload andaccelerate service deployment. So using cloud computing platform in maintainanceinformation center, can not only focus on the maintenance departments of varioushardware resources and information, but also ensure healthy and sustainable operationof repair system. This content of thesis are as follows：First，a detailed and comprehensive research is done about the concept of cloudcomputing and cloud computing platform architecture. the key technology of cloudcomputing is summarized and analyzed, and then a systematic analysis summarizationof cloud platform the characteristics is made. The comprehensive functionality andcommercial assessment of several common cloud computing platform is made.OpenStack compared to several other cloud computing platforms increases hardwareutilization and virtualization, which is suitable for maintance information center for avariety of resource management needs. And then the characteristics and performancerequirements of the maintance information center is analyzed. Based on thecharacteristics and performance requirements of the service center, the overall designbased on the OpenStack cloud platform is proposed.Second, according to its own characteristics of maintenance system informationcenter, the logical structure of the maintenance system information center cloud platform is proposed. The maintenance information center cloud computing platform isrealized based on Web Server Gateway (WSGI), Python Djano, libvirt, KVM andOpenStack nova technology. The platform is mainly composed by the user interfacemodule, the security module, the virtual machine storage module and the core module.Finally, verification tests were conducted on various functional modules basign onthe verification platform of the builded maintenance information center cloud platform.The comparison test is made, the test showes that the cloud platform can effectivelyimprove the efficiency of repair information center management and hardwareutilization.The contributions of this paper are: the cloud computing platform evaluationcriteria is proposed;the maintenance information center cloud computing platform isdesigned and implemented, reducing the workload of the repair information center.
