What is AWS Health Dashboard?
The AWS Health Dashboard gives you a personalized view into the performance and availability of the AWS services underlying your AWS resources. It effectively replaced and combined the "Personal Health Dashboard" and the "Service Health Dashboard".
Key Concepts
1. Personalized View (Your Account)
- Alerts you if your specific EC2 instance is affected by a hardware failure.
- Notifies you of scheduled maintenance for your resources.
2. Service Health (Global)
- Shows the general status of all AWS services in all regions (e.g., "Is S3 down in us-east-1?").
Exam Tips
[!IMPORTANT] "Personalized service health" or "Notifications about maintenance affecting YOUR resources": The answer is AWS Health Dashboard.
[!NOTE] Distinguish between regular CloudWatch (Monitoring your app metrics) and Health Dashboard (Monitoring AWS infrastructure status).
Common Use Cases
- Operational Awareness: Checking if a downtime is your fault or AWS's fault.
- Maintenance Planning: Seeing when an RDS maintenance window is scheduled.
