Simplify AWS Control Tower governance with enhanced AWS CloudFormation Hooks

AWS Cloud Operations Blog

This article explains how AWS Control Tower's enhanced CloudFormation Hooks provide better visibility into proactive control enforcement and deployment failures.

  • New CloudFormation Hook Invocation Summary console page shows detailed execution logs
  • Proactive controls validate resource configurations before creation to prevent compliance drift
  • Detailed error messages help developers understand and fix policy violations quickly
  • Example demonstrates CT.S3.PR.1 control preventing public S3 bucket creation
  • Failed deployments now show specific requirements and remediation steps
  • Shift-left governance approach reduces deployment delays and troubleshooting time

This enhancement simplifies AWS Control Tower governance by providing transparent, actionable feedback when CloudFormation deployments violate proactive controls, enabling faster compliance issue resolution.
