This post demonstrates using AWS CloudFormation StackSets to deploy CloudFormation Hooks from a centralized delegated administrator account to all accounts within an Organization Unit(OU). It provides step-by-step guidance to deploy controls at scale to your AWS Organization as Hooks using StackSets. By following this post, you will learn how to deploy a hook to hundreds of AWS accounts in minutes.
AWS CloudFormation StackSets help deploy CloudFormation stacks to multiple accounts and regions with a single operation. Using service-managed permissions, StackSets automatically generate the IAM roles required to deploy stack instances, eliminating the need for manual creation in each target account prior to deployment. StackSets provide auto-deploy capabilities to deploy stacks to new accounts as they’re added to an Organizational Unit (OU) in AWS Organization. With StackSets, you can deploy AWS well-architected multi-account solutions organization-wide in a single click and target stacks to selected accounts in OUs. You can also leverage StackSets to auto deploy foundational stacks like networking, policies, security, monitoring, disaster recovery, billing, and analytics to new accounts. This ensures consistent security and governance reflecting AWS best practices.
