Answer:

CloudWatch is a metric repository in AWS that monitors and collects data about resources and applications.

CloudWatch is a metric repository in Amazon Web Services (AWS) that monitors and collects data about your AWS resources and applications. It allows you to collect and track metrics, collect and monitor log files, and set alarms. It also provides insights into resource utilization, application performance, and operational health.

For example, you can use CloudWatch to monitor the CPU utilization of an EC2 instance and set a threshold for when an alarm should be triggered if the CPU utilization exceeds a certain percentage. This allows you to proactively take action to address any performance or capacity issues.
