AWS Transit Gateway
Central network transit hub replacing complex mesh VPC peering with a hub-and-spoke model, supporting transitive routing between VPCs and on-premises networks. No managed open-source equivalent; the closest self-managed approach uses FRRouting (open-source BGP/routing daemon) to build a hub router, or a mesh-VPN overlay like Nebula/Tailscale for simpler multi-network connectivity without true dynamic routing.
