Orchestrating Multi-Module Terraform Deployments with Automatic Dependency Resolution

Terragrunt run-all solves a critical infrastructure-as-code challenge by automatically executing Terraform across interconnected infrastructure units in dependency order while parallelizing independent operations. This eliminates manual sequencing errors and dramatically reduces deployment time in complex, multi-module environments. The capability becomes essential in CI/CD pipelines where reliable, repeatable infrastructure changes are critical to system reliability and operational speed.
