How flat-rate cloud billing turns idle developer VMs into silent budget leaks โ and how to detect and fix them using FOCUS billing data.
How credential compromise shows up in cloud billing exports โ the zero-threshold new-region rule, four billing-observable attack phases, and two confirmed 2025 campaigns.
How to detect scheduling misses in cloud billing data โ the weekend/weekday ratio, real incidents ($6,700 Monday bill, $40K/year savings), and a practical fix checklist.
Data transfer misconfiguration โ cross-AZ traffic and NAT Gateway misrouting โ is an architecture tax that compounds with every gigabyte. How to detect it and eliminate it.
Commitment loss is an inverse anomaly โ the bill stays flat while waste climbs to 93%. How to detect the cliff (sudden) and the drift (gradual) using FOCUS CommitmentDiscountStatus.
The runaway pattern fires on persistence, not magnitude โ 4+ of 7 days above baseline. The $47K ECS overnight and $72K Cloud Run incident that nobody caught in time.
The 3-day vs 30-day baseline method for detecting cloud cost spikes โ $120K DDoS autoscaling, Lambda recursion, and why 2x threshold is the right bar.
Resources still billing, delivering nothing โ how to detect configured-and-forgotten resources and over-provisioned commitments using FOCUS ConsumedQuantity.
How missing cost allocation tags turn cloud resources invisible to alert routing โ the $1M sandbox incident, industry stats, and a practical fix checklist.
