When servers crash from full disks, the problem is not mysterious bugs but basic observability. A client was paying three times what they needed for compute, just to store logs.

A company's EC2 instances crashed weekly because local logs filled disk space, forcing them to overprovision compute by 3x just for storage. Moving logs to CloudWatch eliminated crashes, reduced costs by two-thirds, and enabled rapid incident response. The case illustrates how deferring observability infrastructure creates compounding costs in debugging time, reliability, and emergency fixes. Companies that treat logging, monitoring, and tracing as prerequisites rather than overhead avoid expensive crises and operate more efficiently at scale.
