GCP Hybrid VPN Architecture
This Google Cloud hybrid architecture diagram explains a site-to-site VPN connection. An internal application reaches the office LAN and edge firewall. The firewall establishes a tunnel over the internet to Cloud VPN. On the cloud side, Cloud VPN connects the tunnel to a Google Cloud VPC and a Compute Engine workload. The diagram distinguishes the public transport path from the private networks at either end. It is suitable for an early network design or a documentation page. Add redundant tunnels, Cloud Router, subnets, or firewall rules when those details are needed. Keep the diagram current when equipment, cable paths, service ownership, or security boundaries change, so it remains useful for planning and operations.

Scenario
Hybrid connectivity
Key decisions
- Local boundary: The office firewall is the on-premises edge.
- Tunnel endpoint: Cloud VPN terminates the encrypted connection.
- Cloud network: The VPC provides private connectivity to the VM.
When to reuse this
Use this for a basic diagram of a private path between an office application and a workload in Google Cloud.
