The " future hospital" information platform based on cloud architecture, through the deep integration of cloud computing, made full use of the high availability and strong scalability provided by the cloud computing platform, constructed an integrated hospital information platform, and realized the transformation and upgrading of the technical framework of hospital information platform in the era of big data, to meet the needs of homogeneous management and innovative service mode. In order to ensure the reliability of network transmission between cloud data center and hospital, and further ensure medical data security and patient privacy while using cloud computing, the " future hospital" information platform was migrated from the virtual private cloud(VPC)of public cloud to the local private cloud platform of the hospital, realized the hybrid cloud architecture mode of " future hospital" information platform with local proprietary cloud platform as the core and combined with public cloud VPC.
