AWS – AWS Organizations now provides central AWS account closure to enable easier end-to-end account lifecycle management

You can now centrally close member accounts in your AWS Organizations through the console and programmatically via the AWS Command Line Interface (CLI) and SDK. This feature makes it easier and more efficient for you to manage your Amazon Web Services workloads by enabling you to close member accounts from your organization’s management account without needing to login to each member account individually. You can also use IAM permissions to authorize IAM roles or users in your management account to securely perform account closures while protecting mission-critical accounts in your infrastructure.
