Terragrunt Terraform Wrapper

Terragrunt is a thin wrapper around Terraform that solves structural problems Terraform can't address: code duplication across environments, state file management, and orchestrating dependencies between modules. It uses HCL configuration (terragrunt.hcl files) to abstract common settings, allowing you to define environments with minimal repeated code. Terragrunt enables teams to manage infrastructure at scale: 100+ modules across 5+ environments without duplicating configuration. It's particularly valuable for large organizations with complex, multi-region deployments.
