Alarms

CloudWatch alarms notify you when a metric crosses a threshold, helping you catch problems before users notice. Alarms are always based on metrics, so picking the right metrics and thresholds is key. You can set up alarms for things like Lambda errors, API Gateway 5xx errors, or DynamoDB throttles. Alarms can trigger actions like sending notifications via SNS, calling a Lambda, or scaling EC2. AWS provides alarm recommendations and code samples to help you get started.

Major Learnings

•CloudWatch alarms alert you when metrics cross thresholds so you can react to issues early.
•Alarms must be tied to metrics, so it's important to select metrics and set thresholds that match your system's risks.
•Alarms can trigger SNS notifications, Lambda functions, or auto-scaling actions.
•AWS offers alarm recommendations and code samples to help set up common alarms and best practices.

Next Steps

1.Review your system's key metrics and set up alarms for errors, throttles, or quota limits.
2.Use alarm recommendations in the CloudWatch console to find useful default alarms.
3.Connect alarms to SNS or Lambda for notifications and automate alert handling.
4.Document alarm actions and write clear descriptions or runbooks so responders know what to do.
