Clear, interactive, and structured AWS lessons designed for absolute beginners.

CloudWatch Core Concepts

CloudWatch commonly involves metrics, logs, alarms, dashboards and related observability features.

Why it matters

These capabilities help you detect abnormal behavior and troubleshoot failures.

How it works

Collect telemetry → visualize → define threshold or condition → alarm → investigate logs/metrics.

Real-world example: An alarm can notify an operator when an important metric crosses a defined threshold.

Core Concept

Collect metrics and logs → define useful signals → create alarms → respond to alerts.

Good monitoring connects technical signals to application impact.

Real-world example

Use a realistic cloud workload and focus on the responsibility of this AWS service.

User → AWS service → application → data / response

Choose the service that matches the responsibility instead of forcing every workload into one resource.

Practice tip: Build the smallest possible lab, verify the result, then remove resources you no longer need.
