What happens when AWS Control Tower creates an account

New accounts in AWS Control Tower are created and then provisioned by an interaction among AWS Control Tower, AWS Organizations, and AWS Service Catalog. For steps to enroll an existing AWS account using the AWS Control Tower console, see Enroll an existing account.

Behind the scenes of account creation
  1. You initiate the request, for example, from the AWS Control Tower Account Factory page, or directly from the AWS Service Catalog console, or by calling the Service Catalog ProvisionProduct API.

  2. AWS Service Catalog calls AWS Control Tower.

  3. AWS Control Tower begins a workflow, which as a first step calls the AWS Organizations CreateAccount API.

  4. After AWS Organizations creates the account, AWS Control Tower completes the provisioning process by applying blueprints and controls.

  5. Service Catalog continues to poll AWS Control Tower to check for completion of the provisioning process.

  6. When the workflow in AWS Control Tower is complete, Service Catalog finalizes the account's state and informs you (the requester) of the result.
