# EC2 Instance Recovery

* You can create an **CloudWatch alarm that monitors an EC2 instance and automatically recovers the instance if it becomes impaired** due to an underlying hardware failure or a problem that requires AWS involvement to repair.<br>
* A recovered instance is identical to the original instance, including the **instance ID, private IP addresses, Elastic IP addresses, placement group and all instance metadata**.<br>
* When the `StatusCheckFailed_System` alarm is triggered, and the recover action is initiated, you will be **notified by the Amazon SNS topic that you selected when you created the alarm and associated the recover action**.<br>
* When the process is complete, **information is published to the SNS topic you've configured for the alarm**.<br>
* You **will notice an instance reboot on the recovered instance**.
