The initial technical interview was a take-home assessment which I remember being something like the following: You are tasked with building a development environment on Google Cloud Platform (GCP) for a new web application. This environment needs to include: - A virtual machine (VM) instance. - A PostgreSQL database instance for the application's data storage. - Secure access to the VM instance via SSH. Requirements: - Use Terraform to define and provision the infrastructure. - The Postgres database instance should be accessible by the VM instance but not directly exposed to the public internet. Utilize Google Cloud's security best practices. Bonus points: - Can you configure the Terraform code to use environment variables for sensitive information like the GCP project ID or zone? - Can you modify the code to allow SSH access only from specific IP addresses for enhanced security?
