This paper discusses about building the provincial cloud resource management platform based on OpenStack. By integrating the provincial hardware resources, the equipment such as servers and storage and network switching devices are unified and managed through resource pooling. Based on this idea, the formal provincial virtual systems and soft/hardware resources can be managed by the unified platform. After the platform is put to use, the effective utilization rate of resources can increase significantly, which provides hardware resources services to the relevant departments with dynamic, flexibility, and recyclability. With connection to the provincial virtual systems, the platform can quickly deploy the delivery system according to the needs of operation, greatly improve the meteorological service and support capabilities and enhance the capability of system operation. The completion and application of this platform leads, demonstrates, serves and explores the provincial cloud computing research and of great significance to the provincial informatization construction.
