Enforce and share approved Google Cloud product configurations so engineers can deploy and update them consistently. Which approach should you use?

Using Terraform modules with the Google Cloud Terraform provider is the most effective approach for enforcing and sharing approved Google Cloud product configurations. Terraform is an Infrastructure as Code (IaC) tool that allows you to define and provision infrastructure using a declarative configuration language. Modules enable reusability and standardization of configurations, ensuring consistency across deployments. Storing these modules in a source repository facilitates version control, collaboration, and automated deployment pipelines. Bash scripts using the gcloud CLI are imperative and less declarative, making them harder to manage for complex configurations and less suitable for enforcing desired states. Java packages with client libraries require writing application code, which is overkill for infrastructure provisioning and less declarative. Using curl against REST APIs is very low-level, error-prone, and lacks the state management and declarative nature of IaC tools.
