EC2 Image Builder Updates

EC2 Image Builder now supports invoking Lambda functions and executing Step Functions state machines through image workflows. This enables complex, multi-step workflows and custom validation logic in your image creation process, providing greater flexibility and control.

Previously, customers had to write custom code and implement workarounds to integrate Lambda or Step Functions within image workflows, which was cumbersome and error-prone. Now, you can seamlessly invoke Lambda functions for custom logic or orchestrate Step Functions for complex workflows, allowing for use cases like custom compliance validation, custom notifications, and multi-stage security testing.

These capabilities are available at no additional costs in all AWS regions, including AWS China (Beijing) Region, operated by Sinnet, AWS China (Ningxia) Region, operated by NWCD, and AWS GovCloud (US) Regions.
