Instead of copying provider.tf files everywhere, we'll use the generate block. Learn to define provider versions and credentials in a single root file, injecting them into every module automatically to ensure consistency across your fleet.

Defining S3 buckets in every folder is error-prone. We’ll use the remote_state block to define backend logic once at the root, allowing every child module to automatically inherit and configure its own state path dynamically.

This file is the heart of your configuration, replacing standard .tf definitions. We’ll examine how this single entry point defines where your Terraform code lives, what inputs it needs, and how it inherits logic from parent directories.

Terragrunt isn't a replacement; it’s a power-up. Discover how it wraps the standard Terraform binary to dynamically generate configurations, inject arguments, and handle backend logic before handing control over to the core tool you already know.

Workspaces seem easy for environments, but they share the same backend and plugins, making multi-account isolation difficult. We’ll analyze why directory-based separation is safer and more robust for enterprise scale than CLI workspaces.

Copy-pasting provider blocks and backend configs across hundreds of folders is a maintenance nightmare. Learn how native Terraform forces this redundancy and why solving it is the first step toward scalable Infrastructure as Code.
