Connect your VPC to other networks

You can connect your virtual private cloud (VPC) to other networks. For example, other VPCs, the internet, or your on-premises network.

The following diagram demonstrates some of these connectivity options. VPC A is connected to the internet through an internet gateway. The EC2 instance in the private subnet of VPC A can connect to the internet using the NAT gateway in the public subnet of VPC A. VPC B is connected to the internet through an internet gateway. The EC2 instance in the public subnet of VPC B can connect to the internet using the internet gateway. VPC A and VPC B are connected to each other through a VPC peering connection and a transit gateway. The transit gateway has a VPN attachment to a data center. VPC B has a AWS Direct Connect connection to a data center.
