Abstract	Cloud computing has revolutionized the way organizations manage their IT infrastructure, leading to increased adoption of multi-cloud strategies. However, establishing secure connections between different cloud service providers remains a significant challenge. This paper presents a comprehensive solution for connecting private cloud environments across Google Cloud Platform (GCP) and Microsoft Azure using Site-to-Site VPN technology. We demonstrate the implementation of a secure, reliable connection between private cloud networks while maintaining data privacy and ensuring seamless communication. Our approach includes the configuration of virtual networks, subnets, security groups, and VPN gateways, along with thorough testing methodologies to validate the connection’s effectiveness. The experimental results show successful establishment of secure tunnels with latency under 50ms and throughput exceeding 1.5 Gbps, demonstrating the viability of our approach for enterprise grade inter-cloud connectivity.
