StackSets

A CloudFormation feature for deploying stacks across multiple AWS accounts and Regions from a single operation.

Definition

With service-managed permissions and AWS Organizations, StackSets can automatically deploy to new accounts in target OUs. They are commonly used for guardrails and baseline resources.

Example

A StackSet deploys an AWS Config rule to every account in the Production OU in three Regions.

Exam tip

Multi-account, multi-Region CloudFormation deployment = StackSets.
