Hybrid Connectivity via HA VPN — Google Cloud Architecture Template
On-premises connectivity over HA VPN into a custom VPC with hybrid DNS, app VMs, shared NFS via Filestore, and NAT egress.
Why this architecture works
- HA VPN with dual tunnels delivers a 99.99% SLA for site-to-cloud connectivity.
- Hybrid DNS forwarding lets on-prem and cloud resolve each other's names transparently.
- Filestore provides POSIX NFS shares that lift-and-shift apps expect, without a self-managed filer.
- Cloud NAT gives VMs outbound access for patches while keeping them unreachable from the internet.
