Carvana, the leading online vehicle retailer, successfully automated its infrastructure provisioning process using Harness, significantly reducing task completion time from 4 hours to just 20-30 minutes. This automation was crucial during a period of rapid growth, as the company expanded from 7,000 to 21,000 employees. The initiative, led by Sr. Cloud Infrastructure Engineer Richard Taylor, involved implementing infrastructure as code through a project named TURBO, which stands for The Universal Request to Build Orchestrator. TURBO allowed developers to submit requests via a portal, enabling Harness to automatically build the infrastructure, thus alleviating the workload on Carvana's small team of infrastructure engineers. This shift not only streamlined operations but also supported the company's innovative approach to car buying, which eliminates traditional dealership overhead and provides customers with a hassle-free experience and significant cost savings.
