AWS Control Tower now offers single-region support for Terraform through account factory customization. You can now customize new and existing AWS accounts prior to provisioning them from AWS Control Tower using Terraform open source. With this release, you can now use AWS Control Tower and AWS Service Catalog to define account blueprints using Terraform. The account blueprint describes the specific resources and configurations that are used in an account as a template to scale multiple AWS accounts. Now, customers who prefer using Terraform have the same flexibility and immediate access to the account after it is provisioned.
