Implementation plan:
- What are CloudWatch metrics — numerical time-series data
- Built-in metrics: EC2 (CPU, network), ECS (CPU, memory), ALB (request count, latency, 5xx errors)
- Custom metrics (brief concept — not hands-on)
- Metric dimensions and namespaces
- CloudWatch Alarms: threshold-based alerts
- Alarm states: OK, ALARM, INSUFFICIENT_DATA
- Alarm actions: SNS notifications (email alert)
- Practice: create alarms for ECS CPU utilization and ALB 5xx error rate, trigger a test alert
