Advanced VPC Connectivity Patterns
summary
Explains concrete patterns: classic Direct Connect private VIF creates one VLAN and one BGP session per VPC, while Direct Connect Gateway presents a single VLAN/BGP that can carry many VPCs and multiple regions; full-mesh VPC peering scales as n(n−1)/2 (10 VPCs = 45 peers) and hits limits (125 peering connections, ~100 route entries), so Transit Gateway acts as a cloud router with per-attachment route tables; PrivateLink exposes services via NLB + ENIs (cross-account, reachable over Direct Connect/VPN); Route 53 Resolver supports inbound/outbound endpoints but has a 10,000 qps per-endpoint practical limit.
