TE Terraform vs TE Terragrunt

Terraform by HashiCorp is the industry-standard Infrastructure as Code tool that enables teams to provision and manage cloud infrastructure across 2000+ providers using declarative HCL (HashiCorp Configuration Language). It maintains state files to track resource changes, supports modules for reusable infrastructure patterns, and offers workspaces for environment management. Terraform Cloud adds remote state management, policy enforcement, and team collaboration features.

Terragrunt is a thin wrapper for Terraform and OpenTofu that provides extra tools for keeping your code DRY, managing remote state configurations, and handling dependencies between modules. It is especially useful for managing multiple environments (dev/staging/prod) with shared Terraform modules. Features include import/output helpers, run-all for multi-module operations, and built-in S3+DynamoDB state backend configuration.
