Dealer.com, a large automotive dealership website, relies on its site performance and availability to drive business for thousands of dealerships across the country. The site's performance is affected by dozens of discrete services, making it challenging to resolve performance issues and provide good customer experiences. To address this, Dealer.com uses New Relic distributed tracing, which provides end-to-end visibility into complex architectures, allowing teams to capture, visualize, and analyze traces through complex systems. Distributed tracing helps software teams understand the performance of every service, both upstream and downstream, enabling them to resolve performance issues, measure overall system health, and prioritize high-value areas for improvement. New Relic's distributed tracing provides actionable detailed visualizations for various language frameworks and supports common standards like OpenTelemetry and W3C, making it easier to identify insights in the data across the stack.
