The document discusses how Cox Automotive's subsidiary Manheim transformed their IT operations through a DevOps strategy and cloud migration. They faced challenges with tool selection, resource constraints, and managing cloud costs. Their DevOps approach involved creating new roles like Release Engineering and Site Reliability Engineering to automate deployments, reduce downtime, and enable developers. Through these changes, they achieved an 80% automated deployment rate, reduced mean time to recovery, and kept cloud spending within budget while growing their engineering team and migrating over 100 applications to AWS.
