AFT Architecture
Order of operations
You run AFT operations in the AFT management account. For a full account provisioning workflow, the order of stages from left to right in the diagram are as follows:
-
Account requests are created and submitted to the pipeline. You can create and submit more than one account request at a time. Account Factory processes requests in a first-in-first-out order. For more information, see Submit multiple account requests.
-
Each account is provisioned. This stage runs in the AWS Control Tower management account.
-
Global customizations run in the pipelines that are created for each vended account.
-
If customizations are specified in the initial account provisioning requests, the customizations run only on targeted accounts. If you have an account that's already provisioned, you must initiate further customizations manually in the account's pipeline.
