Automatically Healing CloudFormation Drift with Durable Functions
AWS introduced drift-aware change sets in November 2025, enabling automatic detection and repair of configuration drift in CloudFormation stacks. Durable Functions can be used to orchestrate the asynchronous workflow of drift detection and remediation. This approach simplifies state management and improves reliability compared to using standard Lambda functions.
- ▪AWS updated CloudFormation in November 2025 to support drift-aware change sets for automatic drift remediation.
- ▪Drift-aware change sets can be created using the --deployment-mode REVERT_DRIFT option to revert infrastructure to its defined state.
- ▪Durable Functions simplify the orchestration of asynchronous operations like drift detection and change set execution.
- ▪The solution involves detecting drift, creating a drift-aware change set, and applying it to restore configuration compliance.
- ▪A sample implementation uses AWS Lambda, SSM parameters, and Durable Functions to automate the healing process.
