A mid-sized company discovered their AWS CloudWatch logging costs ($127,000/month) exceeded compute costs ($41,000/month) by 3x. Investigation revealed 80% of log volume came from DEBUG statements left in production—including one forgotten line costing $40,000 annually that was never queried. The root cause: adding logs is frictionless for developers while removal requires justification, creating a ratchet effect. The company reduced costs 89% to $14,280/month by enforcing retention policies, changing log levels from DEBUG to INFO, sampling high-traffic endpoints, and making costs visible to engineering teams through dashboards and attribution.
