Explanation:
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 an administrator account, you define and manage an AWS CloudFormation template, and use the template as the basis for provisioning stacks into selected target accounts across specified Regions. This is the most operationally efficient method to deploy and update VPCs uniformly across 50 AWS accounts, handling future updates seamlessly without the need to log into each account individually or manage custom scripts.
