Modules, Environments and Architecture

4 min

Any folder that contains Terraform files is a module. The one you run terraform from is your root module. From this root module, you can call child modules: a local folder, a module published in a registry, or a module kept in a Git repository.

A module groups resources that form a coherent capability. You will come across some, for example, for:

  • an application network;
  • a secured bucket;
  • a database;
  • a web service;
  • monitoring;
  • an application's identity.

Modules make your configurations reusable and allow your organization to offer standardized components, which any team can call without rewriting their content. Official reference — Modules
