3-Tier Web on Compute Engine — Google Cloud Architecture Template
Classic three-tier architecture with load-balanced web VMs, an internal app tier, Cloud SQL, and Memorystore caching.
Why this architecture works
- Separating web, app, and data tiers limits blast radius and lets each tier scale independently.
- An internal load balancer keeps app-tier traffic on private IPs, never exposed to the internet.
- Cloud NAT provides controlled outbound internet access without public IPs on VMs.
- Memorystore offloads hot reads from Cloud SQL, protecting the database under load.
- Managed instance groups behind the external LB enable rolling updates and autohealing.
