This article showcases a prototype VPN-based cloud strategy that uses SoftEther VPN and Microsoft Azure to manage and exchange library management systems and repositories. The prototype was tested for performance, security, and scalability, and the results suggest that the VPN-based cloud strategy is a viable solution for managing distributed library repositories. By using SoftEther VPN and Microsoft Azure, the prototype provided secure communication and scalability to handle large numbers of concurrent users. Future research can explore other VPN technologies and cloud platforms to enhance the prototype\u27s capabilities and evaluate its performance in various scenarios
