• terraform.tfvars: Storage for non-sensitive variables or overrides default values.
• backend.tf: Specification of the backend configuration for remote state storage.

2. Modules

• example_module/: The example module.

Each module contains:

• main.tf: Configuration for that specific module.
• variables.tf: Module-specific variables.
• outputs.tf: Output values specific to that module.

3. Environments

• prod/: Environment-specific configurations for production.
• dev/: Environment-specific configurations for development.

Each environment includes:

• main.tf: Configuration specific to that environment.
• variables.tf: Environment-specific variables.
• outputs.tf: Environment-specific outputs.
