Design and Implementation of Expressway Information System Based on Hybrid Cloud Architecture

长期以来,由于我国高速公路信息系统普遍建立在物理机服务器上,导致存在计算资源利用率低、系统可靠性差、数据管理工作复杂等一系列问题。得益于云技术的快速发展,为解决上述问题,提出一种混合云架构的高速公路信息系统。首先,基于高速公路信息系统智能化及业务需求,设计实现了异构资源整合、硬件虚拟化和统一的数据访问接口,统筹管理计算资源。其次,研究设计两地三中心数据混合云架构系统备份框架,提高系统可靠性。再次,通过模拟分析验证了架构设计的优越性。最后,将以上成果在湖南省高速公路信息系统升级建设中进行应用实践,实测数据表明,与原系统相比,混合云架构平台提高了394%的计算资源利用率、170%的系统稳定性和49%的数据物理安全性,并提供了更加高效便捷的数据管理操作。

For a long time,the expressway information system in China is generally based on the physical machine server,which leads to a series of problems,such as low utilization of computing resources,poor system reliability,complex data management and so on.Thanks to the rapid development of cloud technology,in order to solve the above problems,propose a expressway information system with hybrid cloud architecture.First of all,based on the intelligence and business requirements of expressway information system,the integration of heterogeneous resources,hardware virtualization and unified data access interface are designed and implemented,and computing resources are managed as a whole.Secondly,the backup framework of two-place and three-center data hybrid cloud architecture is studied and designed to improve the reliability of the system.Thirdly,the superiority of architecture design is verified by simulation analysis.Finally,the above achievements are applied in the upgrading and construction of expressway information system in Hunan Province.The measured data show that,compared with the original system,the hybrid cloud architecture platform improves the utilization of computing resources by 394%,system stability by 170%,data physical security by 49%,and provides more efficient and convenient data management operations.
