When Cloud Bills Crash the System: Cost as a Reliability Issue
Cloud cost and system reliability are the same problem viewed through different instruments. Cost anomalies surface bugs, retry storms, and memory leaks before they cause outages — if you're watching. The fix: embed billing telemetry into your observability stack, enforce resource tagging at the pipeline level, write anomaly-based cost alerts, and treat budget overruns as budget burns the same way you treat SLO violations. Manage them separately and you'll always be six weeks behind the failure that caused them.
