Virtualization in railway datacenter management environment

Virtualization is a common technology for improving the utilization of existing physical computing resources, which provides great opportunity for industry growth and research due to its high flexibility and simplification. While various software products are available for providing the infrastructure of virtualization, the deploy for a specific industry area is still challenging. We attempt to apply virtualization technique to the railway datacenter environment so as to simplify the system configuration and improve the utilization of computing resources. To this end, we first compare different virtualization techniques and analyze their performance and limitations in terms of reliability, applicability, flexibility and cost. Then we design a suitable virtualization scheme and develop a virtualized management system by virtualizing the physical servers within the environment. In this paper, the detailed design of the virtualized management system is presented, and some salient features of this system are carefully analyzed.
