In order to overcome the shortage of computer resources, the difficulties in computer maintenance, big data sharing needs in countylevel meteorological service, and problems in the resource integration, the Beijing Meteorological Service established a virtual server cluster and virtual desktop based on virtual technology. The results show that users in countylevel meteorological service can access MICAPS (Meteorological Information Comprehensive Analysis and Process System) and VIPS (Veryshortrange Interactive Prediction System) in the municipal meteorological service, and other library resources in the China Meteorological Administration through a virtual desktop by lowerbandwidth. The virtual server cluster created by the Beijing Meteorological Service is effectively to meet the rapidgrowting demand of server resources. It can be seen that virtualization technology is necessary for the optimization and improvement of information technological resources in the meteorological department.
