We’ve all seen the horror stories of AWS bills. Usually, it's a runaway Lambda or a leaked API key. But some of the most expensive leaks are "passive."
The Ghost Volumes
A startup had a script to delete unattached EBS volumes older than 24 hours. It ran every night. Until it didn't.
For 4 months, the script was failing due to an IAM permission change. No errors were logged because the cron job itself couldn't even launch the script. By the time they noticed, they had accumulated $50,000 in storage fees for junk data.
The Payoff of Monitoring
If that cleanup script had been pings CronRabbit, they would have known within 25 hours that the job had stopped. Total cost of the incident: $400 for one day.
Reliability monitoring isn't just about uptime; it's about financial protection.
