Integration multiple cloudformation stackset with step function

Hi,

You can easily create stacks cross-regions and cross-accounts from 1 central account: see https://aws.amazon.com/blogs/infrastructure-and-automation/multiple-account-multiple-region-aws-cloudformation/

You can easily create the stacksets in sequence by simply having a Step Function (or even a simple lambda) iterating on a Lambda executed in central account to launch each of the stacksets in sequence.

Best,

Didier

Have you thought about using Nested Stacks so that they run in order?

Once you have created a stack set in the Management account, any new account which joins the Org will have them executed automaticlly in the correct order?
