EC2 Image Builder Adds Lambda and Step Functions Support

EC2 Image Builder now natively integrates with AWS Lambda and Step Functions, allowing users to run custom logic and multi-step workflows during image creation. This eliminates the need for complex workarounds, enabling use cases like compliance checks, notifications, and multi-stage security testing directly within Image Builder workflows. These capabilities are available in all AWS regions at no extra cost.
