Letgo Boosts Observability Strategy With New Relic One

Letgo, a mobile app designed for selling second-hand goods, has achieved over 100 million downloads by simplifying local buying and selling. As the app's traffic increased, the company faced challenges in efficiently resolving errors, which initially involved using an ELK Stack that proved cumbersome due to tool sprawl and distributed logging data. To address these issues, Letgo transitioned from EC2 to Kubernetes and adopted New Relic One for a more streamlined observability strategy. This migration allowed their product team to enhance error resolution by offering a consolidated view from high-level Kubernetes clusters to specific transactions, significantly reducing troubleshooting time and allowing developers to focus more on innovation rather than managing external systems.
