AWS CloudFormation StackSets extends the functionality of stacks by enabling you to create, update,

or delete stacks across multiple accounts and regions with a single operation. Using a stack set, the

SysOps administrator can manage deployments across different regions and accounts within AWS

Organizations efficiently.

Setting up StackSets: First, define your CloudFormation template that describes all the resources that

need to be deployed across the regions. Store this template in an S3 bucket accessible by the central

administration account.

Service-Managed Permissions: When creating a stack set, select the option for service-managed

permissions if you are using AWS Organizations. This allows AWS CloudFormation to automatically

set up the necessary permissions in the target accounts.

Deploying the Stack Set: From the central administration account, create the stack set and specify the

target accounts and regions. CloudFormation will then ensure that the resources defined in the

template are instantiated in each of the specified regions and accounts.

This method simplifies management and ensures consistency of infrastructure across multiple

regions and accounts, leveraging the organizational units in AWS Organizations for centralized

governance.
