Amazon CloudWatch is the service designed specifically for monitoring resource utilization and performance metrics across AWS services. It allows users to collect and track metrics, collect log files, and set alarms. This capability enables organizations to monitor their AWS resources in real-time and gain insights into their operational health and performance, which is essential for maintaining efficient cloud environments.

For instance, with Amazon CloudWatch, users can monitor metrics such as CPU usage, memory usage, disk I/O, and network activity for Amazon EC2 instances. Additionally, it can provide information about other AWS services and set alarms based on defined thresholds, allowing for automated responses to specific conditions, thus enhancing overall system reliability and performance.

While other options mentioned can provide certain functionalities related to monitoring or resource management, they do not possess the comprehensive monitoring capabilities that CloudWatch offers. Amazon EC2 is focused on compute resources; AWS Auto Scaling manages the scaling of resources to meet demand; and AWS Config specifically monitors the configurations and compliance of AWS resources rather than performance metrics.
