How would you organize the file structure for Terraform in your project?

The organization of Terraform's file structure in a project depends on the scale and requirements, but generally follows these principles:

• Environment separation — separate folders for dev, staging, prod to isolate configurations and states.

• Modules — grouping reusable components into modules/ folders to avoid code duplication.

• Main configurations — placing main.tf, variables.tf, outputs.tf files in the root or environment folders.

Example structure:

terraform/
├── modules/
│   ├── network/
│   ├── compute/
│   └── database/
├── envs/
│   ├── dev/
│   │   ├── main.tf
│   │   ├── variables.tf
│   │   └── backend.tf
│   ├── staging/
│   └── prod/
└── README.md

This approach facilitates maintenance, scaling, and collaboration on infrastructure.
