Figure 8 - AWS Direct Connect and AWS Transit Gateway
Each AWS Transit Gateway is a network transit hub to interconnect VPCs in the same region, consolidating Amazon VPC routing configuration in one place. This solution simplifies management of connections between an Amazon VPC and your networks over a private connection that can reduce network costs, increase bandwidth throughput, and provide a more consistent network experience than internet-based connections.
