采用云计算实现集中统-的区域医疗信息化建设和维护,不仅降低了大规模区域数据中心建设初期所需的一次性投资成本,同时还满足了快速部署及差异化需求等多方面要求.通过对区域数据中心软硬件资源虚拟化方案的详细讨论,突出展示了云计算在区域医疗信息化建设中的强大功能.云计算不但提高了区域医疗信息的可靠性和使用价值,且通过虚拟化技术实现了软硬件资源的动态按需分配,提高了资源的利用效率,实现了绿色计算.%With the use of cloud computing, the construction and maintenance of regional medical information systems not only reduces the large-scale cost of the initial investment, but also meets the requirement of rapid deployment to different demands. After the detailed discussion of virtualized schemes for software and hardware resources in regional medical center, this paper highlights the strong power of cloud computing in the area of regional medical information system construction. Cloud computing not only greatly improves the reliability and values of medical information, but also enables the dynamic on-demand resources through virtualization technology. Cloud computing really improves the efficiency of resource use and achieves a green computing.
