I have a few compute engine instances in a Google Cloud Platform project. One is my API "api-inst" and is inside a backend-service: api-service One is my db 2db-inst" and is inside a backend-service: db-service
They are both callable through the load balancer. Sometimes the API needs to call the DB.
I would like these calls to be dealt with internally for performance purpose. But I might have several db instances inside my db-service, therefore I cannot make the call through the internal IP
Therefore I wonder if there is a way to make my call directly to the backend service?
