CloudWatch
In plain terms
Amazon's monitoring and observability service.
Going deeper
CloudWatch collects metrics, logs, and events from AWS resources, with alarms and dashboards for monitoring. It's AWS's built-in observability tool.
Under the hood
Metrics, log groups, alarms, and events trigger automated responses; central to AWS operations.
Examples
AWS metrics, log monitoring, alarms, auto-scaling triggers, dashboards.
Think of it like...
Like a control-room dashboard showing the vitals of all your AWS systems.
