Terraform is powerful, but managing multiple environments and modules at scale quickly becomes challenging. In this article, we'll explore Terraform's limitations and why Terragrunt was created.

Discover the most common mistakes engineers make when using Terraform, from state management and module design to collaboration workflows and production best practices.

Learn why local Terraform state does not scale to production, how remote state backends work, and why centralized state is essential for team collaboration and CI/CD.

Learn how to bring existing infrastructure under Terraform management using terraform import and Import Blocks without recreating resources or disrupting production systems.

Learn how to organize a Terraform repository for production environments using modules, environments, and best practices that scale with your infrastructure.

Learn the Terraform features you'll use in almost every real-world project, including for_each, count, locals, dynamic blocks, depends_on, and lifecycle.

Learn what Terraform Data Sources are, when to use them, how Terraform reads existing infrastructure, and how to combine Data Sources with Resources in real-world projects.

Understand how Terraform Providers work behind the scenes, from Resources and Data Sources to communication with external APIs. This is a fundamental concept for using Terraform effectively.

Terraform Modules are more than reusable code. A well-designed module makes infrastructure easier to maintain, scale, and reuse across environments. This article explores module design from a software engineering perspective.

Terraform State is one of the most important yet misunderstood parts of Terraform. Learn what Terraform State is, why Terraform needs it, how it works, and the best practices for managing State in production.
