Managing Multi-Account AWS Organizations with Terraform and Terragrunt

Managing infrastructure across multiple AWS accounts can be challenging. In this post, I demonstrate how to use Terraform and Terragrunt to manage a multi-account AWS Organization efficiently.

Directory Structure

Here's the repository structure I use for managing 20+ AWS accounts:

infra/

│   ├── vpc/
│   ├── ecs-cluster/
│   └── rds/
├── environments/
│   ├── dev/
│   │   ├── us-east-1/
│   │   └── eu-west-1/
