BMW’s CLEA uses Prophet to detect cost anomalies across 14,000 cloud accounts
BMW Group’s in-house FinOps system, Cloud Efficiency Analytics (CLEA), ingests billing exports (including AWS CUR) and builds per-account-service daily forecasts with Prophet to run daily anomaly detection across roughly 14,000 cloud accounts. The serverless pipeline (Step Functions, Lambda, S3, Distributed Map) processes hundreds of thousands of account-service time series in about 20 minutes and alerts owners when actual spend departs from the forecast; the team reports the compute run costs around $50/month.
