Terraform (TF)

The tool that lets you destroy your entire cloud infrastructure with a single terraform apply — and also build it back. Terraform by HashiCorp uses declarative configuration files (HCL) to define infrastructure resources across any cloud provider.

You write what you want, Terraform figures out how to make it happen, and its state file remembers what exists. Just don’t lose that state file. Seriously. Don’t.

Why it matters: Terraform brought Infrastructure as Code to the masses. Click-ops is dead; long live the .tf file.
