Using CloudFormation StackSets to Onboard Hundreds of Member AWS Accounts

Vantage has developed a streamlined process for connecting multiple AWS member accounts using CloudFormation StackSets, enhancing the onboarding experience for users by automating the connection of member accounts to a centralized root account. This approach addresses the challenge of manually connecting numerous accounts, which can be cumbersome and time-consuming, by utilizing StackSets that allow the deployment of the same CloudFormation Stack across multiple accounts. By employing the "service-managed" permission mode, organizations with AWS Organizations already configured can benefit from automatic connection of new member accounts without additional setup. While there is no console UI integration for this process, the use of AWS CLI commands and quick-create links simplifies the setup for users. This automation not only improves security and cost allocation practices but also facilitates independent team operations within larger AWS environments, providing a nearly "1-click" experience for users managing extensive cloud resources.
