Lab: Deploying AWS Control Tower via Terraform

How to deploy AWS Control Tower via Terraform

Already Know Terraform?

If you're already familiar with Terraform, feel free to hop over to the AWS Security Cookbook by Tyler GitHub repository to grab and deploy the code. Otherwise, stick around and we'll walk through it together!

Overview

The Terraform code for this module has been left in a simplified state (i.e., not using modules, loops, or other advanced Terraform features) to be more easily accessible. You can customize it further to meet your specific requirements.

The Terraform resources for setting up an AWS Control Tower landing zone are fairly new and not as feature-rich as what's available in the AWS Management Console. There will be some steps you'll need to perform in the console after deploying your Landing Zone e.g., registering any pre-existing Organizational Units and defining guardrails like region restrictions.

Deploying the Landing Zone does take close to an hour, so be prepared to wait for the resources to be created. Additionally, making changes to the Landing Zone configuration after deployment or enabling more features will take time to update.

The progress can be monitored in the AWS Management Console under the AWS Control Tower service.
