How I automated AWS cost alerts in 2 hours (and saved $500/month)
Working on CloudWise, I ran into this exact challenge and wanted to share what I learned.
The Problem:
Manual tracking of AWS spending led to delays in identifying overspend, risking budget overruns.
My Approach:
I leveraged CloudWatch and Lambda to create real-time cost alerts based on usage thresholds.
Results:
Automated alerts sent notifications at $100 increments, saving $500/month by enabling proactive resource adjustments.
Implementation Steps:
- Set up CloudWatch to monitor spending metrics.
- Create a Lambda function to trigger alerts.
- Integrate SNS for alert notifications.
Pro Tip for Indie Hackers:
Use AWS Cost Explorer APIs to refine alert criteria and target specific services for optimization.
This saved me hours of debugging and might help your projects too.
Anyone else dealt with AWS cost management? What approaches worked for you?

The incremental threshold approach is smart - getting $100 alerts instead of waiting for a big surprise at month end makes a real difference. Did you run into any issues with CloudWatch lag on the cost data? Last time I tried this the metrics were delayed by several hours which made real-time alerts less useful.
