This article introduces the concept of open VPN technology and puts forward a design scheme using open VPN gateway access, which solves the problem of direct reporting of users accessing the system from the external network. At the same time, the paper uses big data analysis based on the ArcGIS Dashboard design to implement a visual and interactive real-time monitoring system of the global epidemic situation, which can timely and effectively obtain the development of the 2019 coronavirus disease epidemic. The system emphasizes fast and convenient online dynamic display of the global distribution of the epidemic, real-time statistical analysis of the spatial distribution of the epidemic, dynamic display of the severity of the epidemic in various countries and regions and the development trend of the global epidemic, and promotes epidemic monitoring to a certain extent Work development.
