VPC peering
If you wanted to connect two VPCs, AWS offers VPC peering, which allows instances in two VPCs to communicate, as if they're in the same network:
Both VPCs must be in the same AWS region, but they do not have to share the same AWS account. For security purposes, peer VPCs cannot share other connections, such as gateways or other peer connections. If two VPCs are peered with the same VPC, they still cannot communicate with one another, unless you peer them directly. In the next section, we will secure our VPC using network access control lists, and Bastion instances.
