Cloud VPN securely extends your peer network to your Virtual Private Cloud (VPC) network through an IPsec VPN connection. The VPN connection encrypts traffic traveling between the networks, with one VPN gateway handling encryption and the other handling decryption. This process protects your data during transmission. You can also connect two VPC networks together by connecting two Cloud VPN instances. You cannot use Cloud VPN to route traffic to the public internet; it is designed for secure communication between private networks.
