Houzz, a leading platform for home remodeling and design, undertook a significant upgrade of its tech stack to address scalability challenges and enhance operational efficiency. The company transitioned from monoliths to microservices and revamped their observability tools by adopting Grafana Loki for log visibility and Grafana Tempo for tracing. This shift aimed to streamline log searches and improve network observability amidst growing data volumes. By implementing these tools, Houzz reduced Mean Time to Resolution (MTTR) and Mean Time to Identify (MTTI), leading to increased uptime and improved developer and customer satisfaction. The integration of Grafana's tools allows Houzz to efficiently correlate metrics, logs, and traces, providing a unified view of system performance and issues, thereby enhancing their ability to diagnose and resolve problems quickly.
