Key facts
  • How BMW Group detects cost anomalies across 14,000 cloud accounts This post is co-written with Philipp Karg from BMW Group and Christopher Masurek from Data Reply.
  • Cost anomalies are hard to spot when you run 14,000 cloud accounts.
  • BMW Group operates Cloud Efficiency Analytics (CLEA), an in-house FinOps system built on AWS with Reply that monitors more than 14,000 cloud accounts across BMW Group’s cloud estate.
  • CLEA began as a set of dashboards in Amazon Quick Sight , which gave BMW employees visibility into their cloud spend.
  • But a dashboard shows what already happened, and only when someone opens it.
  • To close that gap, CLEA now runs anomaly detection every day and sends email to account owners when spending departs from its expected pattern.
