This article describes a serverless monitoring solution for tracking Amazon RDS and Aurora parameter group changes using CloudTrail, EventBridge, Lambda, and SNS.

• Automated alerts notify stakeholders when parameter groups are modified
• Identifies which databases are affected and whether restart is required
• CloudTrail captures API calls; EventBridge filters and triggers Lambda function
• Lambda extracts change details and publishes formatted notifications via SNS
• Solution prevents unplanned service interruptions and operational confusion
• Includes step-by-step implementation guide with AWS Console and CLI examples
• Testing example demonstrates static parameter change detection and alerting
• Extensible to integrate with Slack, PagerDuty, DynamoDB, or CloudWatch

This serverless architecture provides real-time visibility into RDS parameter changes, enabling proactive maintenance planning and reducing database downtime risk.
