App Engine & Cloud Run in VPC

[Stuart Henderson]

Hi

I am setting up a front-end in App Engine which speaks to a back-end in Cloud Run and I'd like all the traffic to be private (internal only). 

Is it necessary to use a serverless VPC Connector for this?

I had pictured just adding these resources to the VPC subnet for the relevant region. Any pointers would be very welcome!

Thanks.

The VPC serverless connectors would work well for this purpose, since they are used to connect your serverless services to a VPC with internal IP addresses. This ensures that the connection between the front and back ends goes through the VPC and not the internet.

This documentation should be a starting point to know more about VPC serverless access.
