What Are a VPC, a VPN Gateway, and a VPN Connection?
VPC enables you to create private, isolated virtual networks. You can use VPN to securely access ECSs in VPCs.
A VPN gateway is an egress gateway for a VPC. With a VPN gateway, you can create a secure, reliable, and encrypted connection between a VPC and an on-premises data center or between two VPCs in different regions.
A VPN connection is a secure and reliable IPsec encrypted communications tunnel established between a VPN gateway and the remote gateway in an on-premises data center.
To create a VPN on the cloud, perform the following operations:
- Create a VPN gateway. You need to specify the VPC to be connected, as well as the bandwidth and EIPs of the VPN gateway.
- Create a VPN connection. You need to specify the gateway EIP used to connect to the remote gateway, subnets, and negotiation policies.
