Networking foundations: Establish VPC connectivity
summary
Covers concrete VPC choices: pick IPv4/IPv6 blocks (/16 ≈ 65k addresses, /28 ≈ 16 addresses; IPv6 /56 one block), create AZ-scoped subnets, use ENIs, and enforce security with NACLs (stateless) and security groups (stateful). Shows Internet gateway + public IPs, NAT gateways for IPv4 egress and egress-only Internet gateway for IPv6, and VPC endpoints (PrivateLink interface and S3 gateway) to avoid Internet egress. Compares connectivity: VPC peering limit 125, Transit Gateway supports 5,000 VPCs and 50 Gbps per attachment, PrivateLink ENIs ~10 Gbps, and Direct Connect + VPN options.
