Which service can be used to monitor the health of instances behind an Elastic Load Balancer?

AWS CloudWatch
AWS Config
AWS Inspector
Amazon S3

The correct answer is: AWS CloudWatch

The most appropriate service for monitoring the health of instances behind an Elastic Load Balancer is AWS CloudWatch. This service provides a variety of monitoring capabilities, including the ability to track metrics such as CPU usage, disk reads and writes, and network traffic. Specifically for Elastic Load Balancers, CloudWatch can also be used to monitor the status and health checks of the target instances. By leveraging CloudWatch, users can set alarms to notify them of issues, view metrics in the CloudWatch console, and create dashboards that give real-time insights into the health of their application. This comprehensive monitoring supports proactive management of instance health and improves the overall resilience and reliability of applications running behind an Elastic Load Balancer. In contrast, AWS Config focuses on resource configurations and compliance, making it unsuitable for real-time health monitoring. AWS Inspector is primarily used for security assessments of applications, while Amazon S3 is an object storage service and does not provide monitoring functionalities for instance health.
