Today, AWS 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 AWS account.
Customers use stack sets to provision and manage stacks in multiple AWS 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 code for similar functions. With this launch, you use the Regions parameter in DescribeStackSet to return a compiled list of Regions where a given stack set is deployed programmatically. For example, if your stack set is deployed across 100+ AWS accounts in us-east-1 and eu-west-2, you can use the new parameter and return an array [“us-east-1”, “us-west-2”]. You can use this information to strategize for future deployments such as deploying dependent resources or stacks, and more.
You can use these features via AWS Command Line Interface, and AWS Software Development Kits (SDKs). These features are available in US East (Ohio and N. Virginia), US West (N. California and Oregon), Africa (Cape Town), Asia Pacific (Hong Kong, Jakarta, Mumbai, Osaka, Seoul, Singapore, Sydney, and Tokyo), Canada (Central), China (Beijing) operated by Sinnet, and China (Ningxia), operated by NWCD, Europe (Frankfurt, Ireland, London, Milan, Paris, and Stockholm), Middle East (Bahrain), South America (São Paulo), and AWS GovCloud (US) Regions.
