Introduction
This article introduces one of the most common Terraform problems that Terramate was designed to solve: How to decompose code into more manageable components while maintaining system integrity and reliability.
We are not concerned here with Terraform modules, for a while they do allow us to break out code into reusable, versionable units that can be maintained separately, the modules must still be called from somewhere: the Terraform “root module” — i.e., the directory where you run terraform apply, which for this article we will refer to as a "stack.”
