Today, Amazon CloudFormation StackSets adds a new parameter in DescribeStackSet API to improve visibility to the list of Regions where a given stack set is deployed. You can now access the list of Regions directly through your management or delegated administrator Amazon Web Services account.

Customers use stack sets to provision and manage stacks in multiple Amazon Web Services accounts and Regions in a single operation. Previously, customers had to manually aggregate the list of Regions where stack instances were deployed, or build custom codes for similar functions. With this launch, you use Regions parameter in DescribeStackSet to return a compiled list of Regions where a given stack set is deployed programatically. For example, if your stack set is deployed in across 100+ Amazon Web Services accounts in cn-north-1 and cn-northwest-1, you can use the new parameter and return an array [“cn-north-1”, “cn-northwest-1”]. You can use this information to strategize for future deployments.

You can use these features via Amazon Command Line Interface, and Amazon Software Development Kits (SDKs). These features are now available in the Amazon Web Services China (Beijing) Region, operated by Sinnet, and the Amazon Web Services China (Ningxia) Region, operated by NWCD.
