VPC peering connections

When we need to connect one VPC to other VPCs that we have created inside our environment, we can use VPC peering connections. A VPC peering connection is a networking connection between two VPCs that enables you to route traffic between them privately and have the ability to connect instances in private subnets within separate VPCs to communicate directly.
