Integration & Automation Blog

This article demonstrates how to automate external system updates when AWS Control Tower creates new accounts using EventBridge and Lambda.

  • EventBridge monitors Control Tower CreateManagedAccount API calls and triggers Lambda
  • Lambda function extracts account details and creates AWS Support cases for AMS onboarding
  • Failures automatically send notifications to SNS topic for operational visibility
  • Solution uses CloudFormation with IAM roles, KMS encryption, and error handling
  • Adaptable to other systems: inventory management, CMDB, security checks, billing systems
  • Requires AWS Enterprise Support for AMS use case; Business Support for others

This automation eliminates manual account onboarding notifications and ensures consistent external system updates at scale.
