Shared VPC Hub-and-Spoke — Google Cloud Architecture Template
A hub VPC with HA VPN to on-prem, peered prod and dev spoke VPCs, centralized NAT, and private DNS.
Why this architecture works
- Centralizing hybrid connectivity in the hub means one VPN estate instead of one per environment.
- Prod and dev spokes are isolated from each other by default; all cross-traffic transits the hub policy point.
- Shared Cloud NAT in the hub gives audited, centralized egress without public IPs on workloads.
- Private Cloud DNS zones resolve consistently across hub, spokes, and on-prem.
- Network-admin IAM on the hub separates network governance from workload teams.
