In order to meet the needs of meteorological modernization and save resources, the design and application of meteorological resource pool are studied,which contains the construction of the server, storage resource pool,desktop and application resource pool,as well as the operational integration of the provincial, city, and county levels,and the innovation of “cloud+end” and mobility is conducted. Key technology, such as the composition of cloud computing, core technology, virtualization storing, application virtualization technology, network virtualization technology,and the mainstream methods are introduced. The overall architecture of the Anhui provincial meteorological service cloud platform,the server and storage resource pool, the virtual application and desktop resource pool and the methods of cloud platform management are presented. The performance comparison of traditional PC and desktop cloud systems and the comparison of fault handling reliability tests are conducted. The resource utilization and maintenance efficiency are improved after adopting cloud computing, and the 24hours power consumption and the preparation cycle of the server are reduced. The influencing and maintenance time of software failure is reduced. The result shows that the construction of the private cloud has practical application value.
