Hi Marco,
Thank you for taking the time to provide such a detailed and technically accurate observation — you’re absolutely right.
SSM Parameter Store is not an AMI discovery service, and the explanation as written does skip over a critical prerequisite: an external automation process (such as a Lambda function, CI/CD pipeline, or a build tool like Packer) must first write the latest AMI ID into Parameter Store before CloudFormation can reference it. Without that upstream process in place, the integration with CloudFormation doesn’t work on its own.
We have updated the explanation to include this important context so it no longer misleads anyone studying this topic. The changes will be reflected on the portal shortly.
We truly appreciate feedback like yours; it helps us maintain the accuracy and depth of our content for everyone preparing for the exam.
Best regards,
Irene @ Tutorials Dojo
