How BMW Group detects cost anomalies across 14,000 cloud accounts

Amazon Web Services 1 month ago 21

BMW Group uses CLEA, an in-house FinOps system on AWS, to monitor 14,000 cloud accounts and run daily cost anomaly detection instead of relying on on-demand dashboards. The pipeline trains Prophet models on 365 days of daily cost history per account-service pair and completes a full 14,000-account run in about 20 minutes. As a result, CLEA forecasts expected daily spend with confidence intervals, filters deviations to reduce false alerts, and emails account owners actionable anomaly reports each day.
