云计算具有大规模、虚拟化、高可靠性、通用性、高可扩展性、按需服务和价格低廉等优势,目前已在许多领域应用.本文设计一套基于云计算开放架构(CCOA,Cloud Computing Open Architecture)的全路运营支撑系统平台,实现多个系统共享一个云平台,集中建设,集中维护,节约开支,避免大量的重复性建设,并且在系统容灾上具有一定优势.%Cloud computing, have gained the effective applications in various fields currently. It has advantages such as largescale, virtualization, high reliability, versatility, high scalability, on-demand service, low cost and so on. This paper presented a design of platform for the Railway Operation Support System based on CCOA (Cloud Computing Open Architecture) in order to implement the sharing of one cloud platform for multiple system. Using this kind of design, the System could not only concentrate on construction and protection, avoid a large number of repetitive constructions, but also had great advantages on system disaster recovery.
