You have a development environment using Compute Engine and Cloud SQL. Security forbids network routes between dev and prod. Following Google-recommended practices, what should you do to create a production environment?

Creating a new project for production is the recommended practice for strong isolation between environments. Projects provide a robust security boundary, ensuring that development and production resources are completely separate and cannot inadvertently communicate, which aligns with the security team's requirement to forbid network routes between dev and prod. Enabling the necessary APIs ensures the services are available. Creating a new subnet in the existing VPC (and project) would not provide the necessary isolation, as resources in different subnets within the same VPC can still communicate unless explicitly blocked by firewall rules, which is less secure than project-level separation. Using Shared VPC would allow network connectivity between projects, which directly contradicts the security requirement. Requesting Project Editor in another division's project is inappropriate as it grants excessive permissions and violates the principle of least privilege, and doesn't guarantee the necessary isolation or control over the environment.
