Build Centralized Alerting across your organization with CloudWatch, EventBridge, Lambda, and CDK

Learn how to build a centralized alerting system across AWS Organizations using CloudWatch, EventBridge, Lambda, and CDK. The architecture uses StackSets to deploy EventBridge rules across member accounts, forwarding all CloudWatch alarms to a central observability account where a Lambda function processes and routes them to messaging platforms like Discord or Slack. This approach simplifies alert management for developers who only need to create alarms without worrying about routing logic, while platform teams maintain a unified alerting infrastructure across production and development environments.
