AWS Health Service Event Notifications Overview
The AWS Health Service provides a way to receive notifications and automate responses to various events affecting your AWS resources. This is achieved through the integration of AWS Health with AWS EventBridge and other AWS services like SNS (Simple Notification Service), Lambda, SQS (Simple Queue Service), and Kinesis Data Streams. Here's how it works:
- Health Dashboard Triggers EventBridge: Events from the AWS Health Dashboard, such as updates to EC2 instances or exposed IAM keys, trigger EventBridge.
- EventBridge to SNS: EventBridge can then trigger SNS to send email notifications about these events.
- Automation for Corrective Actions: Beyond notifications, EventBridge can also trigger Lambda functions to automatically take corrective actions, such as deleting exposed IAM keys or restarting EC2 instances scheduled for retirement.
Key Concepts and Use Cases
- Real-Time Notifications: Receive email notifications for events like EC2 instance updates directly in your account.
- Account and Public Events: Be informed about both account-specific events (e.g., resource updates) and public events (e.g., regional service availability).
- Automated Corrective Actions: Automate responses to events, such as deleting exposed IAM keys or restarting EC2 instances, using EventBridge integrations.
Examples of Automated Responses
- Exposed IAM Keys:
- Event: Exposed IAM keys detected.
- Action: Trigger a Lambda function via EventBridge to automatically delete the exposed access keys.
- EC2 Instances Scheduled for Retirement:
- Event: Notification of EC2 instances scheduled for retirement.
- Action: EventBridge triggers an action to automatically restart the instance, thereby addressing the issue without manual intervention.
Integrations and Actions
- AWS Services Integration: Leverage EventBridge integrations with Lambda, SNS, SQS, and Kinesis Data Streams for a wide range of automated actions in response to health events.
- Customizable Responses: Tailor the response to specific events using Lambda functions to execute custom scripts or actions based on the nature of the notification.
This system of event notifications and automated responses enhances the ability to maintain the health and security of AWS resources, ensuring timely awareness and reaction to potential issues.
