Some operations don't have to be performed during the runtime of your application. They are typically run during the deployment and therefore may be automated in shell scripts, for example. One such use case is invoking a CLI tool to create a new VPC:
gcloud compute networks create database --description "A VPC to access the database from private instances"
We use the gcloud CLI tool from Google Cloud Platform to create a network called database that will be used to handle traffic from the private instances to the database.
