Real-time database notifications and email alerts play a crucial role in keeping stakeholders informed about critical events and data changes. Even in an age where flashy observability and dashboarding services are all the rage, many (the Data Scientist in me would argue too many) C-Suite executives spend most of their time in meetings and responding to emails. When a KPI dashboard or application error alert is too removed from your key decision makers - this architecture pattern leverages Amazon SES triggered via Lambda to look for and send reports on key data changes right into a leader’s inbox.

Deep Dive: 

AWS RDS (Relational Database Service):
AWS RDS offers managed database instances, allowing you to set up, operate, and scale relational databases in the cloud. It supports popular database engines like MySQL, PostgreSQL, and more.

AWS Lambda:
AWS Lambda enables serverless event-driven computing, allowing you to run code in response to database events or triggers.

AWS SES (Simple Email Service):
AWS SES is a scalable and cost-effective email service that enables sending email notifications and alerts.

Architecture Overview:

  • Database Events: AWS RDS database events, such as data changes, updates, or specific conditions, trigger Lambda functions.

  • Lambda Function: The Lambda function is invoked in response to the database event. It processes the event, generates relevant data, and triggers email alerts.

  • Email Generation: The Lambda function utilizes AWS SES to send customized email notifications to designated recipients.

  • Recipient Notification: Stakeholders receive real-time email alerts containing relevant information about the triggered event.


  • Real-time Alerts: Database events trigger immediate notifications, allowing stakeholders to respond promptly to critical situations.

  • Automated Processes: Lambda automates the process of event detection, data processing, and email generation.

  • Scalability: AWS RDS, Lambda, and SES can handle a large number of events and alerts as your application scales.

  • Cost Efficiency: The serverless nature of Lambda and the pay-as-you-go model of SES contribute to cost-effective event handling.


  • Security: Implement appropriate security measures to ensure that sensitive data is handled securely, both in the Lambda function and during email transmission.

  • Error Handling: Design the Lambda function to handle potential errors and failures to ensure reliable notifications.

  • Recipient Management: Keep recipient lists up to date and configure SES to handle bounces and complaints to maintain email deliverability.
