云计算模型在铁路大规模数据处理中的应用

Research on Cloud Computing and Its Application in Railway

对铁路行业的计算资源、数据处理进行了特征分析.探讨了云计算模型中的虚拟化技术在铁路计算资源整合及MapReduce编程模型在大规模数据处理中的应用模式.采用Hadoop开源平台和Intel的虚拟化管理平台Tashi,提出和实现了基于云计算技术的铁路数据处理框架模型,并通过大规模的货票数据处理实例验证了框架模型的可扩展性和高效性.

This paper analyzes the characteristics of the computing resources and data processing in China railway. Virtualization is utilized for railway resource integration and MapReduce programming model is utilized for railway large-scale data processing. Founding on Hadoop and a virtualization management platform Tashi, this paper proposes and implements a railway data processing framework. A freight invoice data processing application has verified the scalability and the high efficient may be seen in our effort.
