For the purpose of promoting railway digitalization,CHINA RAILWAY explicitly proposes,in its 14th Five-Year Plan for cyberspace affairs,that the railway cloud data center will adopt multi-site and multi-center layout.In an effort to meet the requirements of multi-cloud deployment and realize the unified management and resource scheduling of multi-site and multi-center railway cloud resources,this paper proposes a multi-cloud management platform which is based on the VDC tenant model.The key technologies such as unified management of heterogeneous resource pools,unified multi-cloud resource orchestration,and unified planning of multi-cloud resource capacity are studied,and the current situation and prospect of railway data centers are discussed,thus providing significant support for the O&M management of railway multi-cloud environment.
