AWS provides various services and features that can be harnessed to automate the recovery of unhealthy instances. AWS Auto Scaling monitors your applications and automatically adjusts capacity to maintain steady, predictable performance at the lowest possible cost. When combined with Amazon CloudWatch alarms, AWS Auto Scaling can trigger the replacement of impaired or unhealthy EC2 instances to maintain availability without manual intervention. It is essential to understand how these tools can be used together to automate recovery actions and ensure infrastructure integrity.
