StackSets
StackSets extends the functionality of stacks by enabling you to create, update, or delete stacks across multiple accounts and regions with a single CloudFormation template. This is particularly useful for deploying standardized infrastructure environments, managing resources consistently across your organization, and expediting disaster recovery scenarios. StackSets takes care of safely provisioning, updating, or deleting stacks in the specified accounts and regions, with options to conduct these operations sequentially or concurrently. You can also define failure tolerance and maximum concurrency for your StackSet operations, providing fine-grained control over how changes propagate across your accounts and regions.
