The paper introduces the concept and characteristics of the virtualized cloud platform for hospitals, and mainly discusses the overall and physical architecture of the platform. The overall architecture consists of the infrastructure layers, virtualized layers, platform management layer and platform service layer. The physical architecture can be divided into the storage pool, the SAN network pool, the computational memory pool,high speed network pool and the service application pool. In the end, it describes problems that should be noticed at the time of platform construction.
