    Hi Mike,

    Thank you for posting your question. We have made the required changes for this particular scenario, and the updated content will be available soon.

    It is true that there’s a built-in recovery failure feature for Amazon EC2 that was launched on March last year. However, take note that this is not a silver bullet and has certain restrictions, such as the following:

    – It is only supported on certain EC2 instance types

    – Instances that use Elastic Fabric Adapter (EFA) are not supported

    – Instance with Instance Stores for storage are not supported.

    – You cannot implement customized actions when the instance experience an outage (unlike the EventBridge-based option, where you’ll have more control)

    These are one of the reasons why the use of built-in instance recovery is not recommended. Nonetheless, we do agree that this item must be updated, just as what we’ve done today.

    Thanks again for sharing your thoughts and let us know if you need further assistance. The Tutorials Dojo team is dedicated to help you pass your AWS exam on your first try!
