Cloud Migration of High-Speed Railway CTC System

As cloud computing technology advances rapidly, various industries are evaluating the possibility of transitioning their systems to the cloud. This paper presents a case study on the cloud migration of high-speed railway centralized traffic control (CTC) systems, a critical component responsible for safe and efficient railway operations. In this study, we emphasize our contributions and originality in the following aspects: 1. Resource Utilization Enhancement: We have designed and im-plemented a high-availability cloud platform using OpenStack to promote resource utilization and facilitate resource sharing among different components of the high-speed railway signaling system. 2. Comprehensive Migration Details:Our paper provides a comprehensive overview of the migration process of the CTC system to the cloud platform. This includes intricate details about the high-availability cluster architecture, deployment procedures, and a thorough analysis of fault reconstruction performance. 3. Performance Enhancement: Through our study, we demonstrate that the proposed OpenStack-based cloud platform significantly enhances scalability, flexibility, and cost-effectiveness, all while upholding the essential reliability and safety standards required for railway operations. In conclusion, our work introduces a high-availability cloud platform for high-speed railway signaling systems based on OpenStack. This platform ensures the safe and dependable operation of railways, contributing to the ongoing evolution of cloud technology in critical infrastructure.
