AWS Networking Deep Dive: VPC Peering, Transit Gateway, and Direct Connect

<p>Follow Priya Sundaram, a network engineer at Tidewater Logistics, as a simple two-VPC peering connection turns into a four-VPC mesh with no transitive routing, then gets replaced by a Transit Gateway hub with per-attachment route tables for real isolation. From there the network reaches outside AWS entirely: one internal API exposed privately through PrivateLink, a warehouse connected over Site-to-Site VPN with a Direct Connect upgrade path planned, and Route 53 tying DNS together across every VPC. By the end, four distinct AWS networking tools fit together as one coherent, growing system instead of four disconnected topics.</p>
