Question

A data engineering team runs a Cloud Run service that must reach a Cloud SQL instance and several Compute Engine VMs over private IPs in a custom-mode VPC. The service experiences bursty traffic that occasionally spikes to very high sustained egress throughput, and the team wants to minimize the operational overhead of managing throughput-limited infrastructure while keeping traffic on internal IP addresses. Which egress configuration should they choose?

Accepted Answer

Use Direct VPC egress, assigning the Cloud Run service to a subnet in the VPC

Answer

Use a Serverless VPC Access connector sized with the largest available machine type and manual scaling

Answer

Route egress through a Cloud NAT gateway attached to the VPC so Cloud Run reaches the private resources

Answer

Enable Private Google Access on the target subnet and let Cloud Run connect automatically
