AWS private connectivity patterns
Deploy and compare five private cross-account patterns — VPC Peering, PrivateLink, VPC Lattice, Transit Gateway, and Cloud WAN.
Side-by-side guidance for five independent private connectivity patterns across a shared-services hub and a consumer spoke — OSI layer, CIDR overlap, cost drivers, and when to choose each.
Deploy one pattern at a time (shared-services then consumer), verify with curl via Session Manager, then tear down before the next. Cloud WAN covers multi-region segments and why RAM sharing of the global core network uses us-east-1.
