Terralith

A monolithic Terraform "root module" is also known as a Terralith. It's characterized by an expansive, all-encompassing Terraform configuration that attempts to manage every aspect of the infrastructure within a single module.

In Atmos, this is considered an anti-pattern; instead, this should be broken down into components and configured with stacks.
