You can now submit multiple operations for simultaneous execution with AWS CloudFormation StackSets

Today, AWS CloudFormation StackSets announces the capability to execute multiple operations for simultaneous execution. StackSets extends the functionality of CloudFormation stacks by letting you create, update, or delete stacks across multiple AWS accounts and Regions with a single operation. You can now submit more than one operation per stack set to be executed concurrently. This capability will enable you to reduce overall processing times with StackSets. Additionally, you can avoid the overhead of building logic to batch and queue operations submitted to StackSets.
