Abstract: In order to accelerate informatization of water-conservancy scientific research, we study the cloud computing system and applied technologies for water scientific research, and 5 demands for cloud computing application in management, scientific research, office automation, integrated data center and intelligent river basin research are demonstrated; the architectural design of cloud computing system is completed with adoption of the prevailing X86 architecture and the virtualization technology for resource pooling; the scale of resource pool and the grade of equipment are obtained according to the current equipment utilization and the calculation results of 5 demands; and the cloud operation system is determined by comparison. The technical discussion on operation mode, storage mode and safety of cloud computing system for water scientific research is carried out. In association with design, the infrastructures of cloud computing system has been established and put into operation, and relevant applications are promoted in an orderly way.
