Based on the vSphere architecture, the Ningbo Meteorological Service deployed the meteorological private cloud which simplifies terminal managing and improves work efficiency. The private cloud supplies the standard operational environment with an innovation model for the staffs, regardless of wherever and whenever they are and whichever equipment they use. The resource utilization rate is raised by sharing the resource pool. It allows all kinds of terminals to visit the internal resources more safely, and integrates terminal management to the data center. All these help weather forecasters concentrate on key meteorological tasks.The architecture design of the private cloud is introduced, and the key technologies such as desktop virtualization, software virtualization, safety design, and optimization of user experiences involved in system deployment and application are elaborated.Application of the private cloud in the Ningbo Meteorological Service shows great potential in meteorological service.
