Cloud NAT

Cloud NAT handles outbound traffic for instances without public IPs, acting as a managed gateway for private subnets. It translates private addresses to public ones, enabling secure internet access for resources in isolated networks while maintaining scalability and reliability under load. This setup is essential for workloads that need egress connectivity but must remain hidden from direct inbound connections.

This service suits teams running private instances that require internet access without exposing them to the public web. The main friction point is the lack of a free tier, meaning every byte of translated traffic incurs a cost under the pay-as-you-go model. For small test environments or low-volume projects, this mandatory billing can make the service feel unnecessarily expensive compared to alternatives with included allowances.
