Question
A company runs several production workloads on Amazon EC2 instances. A SysOps administrator discovered that a production EC2 instance failed a system health check.

Explanation
EC2 status checks run every minute and expose a System check metric that indicates hardware or system-level impairment. CloudWatch alarms can trigger on Status Check Failed: System and automatically recover the instance (or take a defined action) without manual intervention, satisfying both the automatic recovery and alerting requirements. This approach minimizes manual steps and scales across many instances, leveraging built-in AWS health signals and standard notification channels. It is also consistent with AWS guidance on using CloudWatch alarms to recover impaired instances and to notify via SNS.
