A Cloud Test Bed for China Railway Enterprise Data Center

China Railway consists of eighteen regional bureaus, geographically distributed across China, with each regional bureau having their own regional data center. Physically distributed and managed at a regional level, the information system of China Railway is a highly complex distributed mission critical system, integrated in networks but largely isolated in term of system resources with application silos, which is a key barrier for China Railway to drive its digital railway vision that is based on fully shared compute infrastructure and applications. The following diagram illustrates the three levels in the information system of China Railway.

Overall, the current information system of China Railway has the following key characteristics:
• Geographically distributed data centers
• Tightly-coupled system integration
• Geo-oriented applications
• Independent resource usages
• Multi-level usages and different user types
• Multiple application subsystems

As an example, the railway freight transportation system manages the freight ticket information in China Railway. It consists of freight ticket sub-system, confirmation and reporting sub-system, and train dispatching sub-system. A freight ticket contains information of freight ID, source and destination information, and detailed status information of freight once it is registered for transportation. There are 120,000 freight tickets generated every day in China Railway, each is 4KB in size. The tracking period is normally 45 days, and the ticket needs to be stored online for one year. Therefore, 160GB data is generated per day and the amount of data in ready-to-be-searched state is over one Terabyte. In addition, 4-6 replicas of the data are required and must be considered.
