Kambi, a rapidly growing sports betting technology company, faced challenges with its in-house Graphite solution for monitoring metrics, which was overwhelmed by the volume of data from its 500 microservices and 200,000 incoming metrics messages per second. To address these issues, Kambi developed an open-source tool called Hadrianus to manage traffic and reduce load but ultimately opted for a more scalable solution by migrating to Grafana Cloud. This transition allowed Kambi to handle its data more effectively while providing a familiar user experience for its development teams, as Grafana Cloud supports both Graphite and Prometheus, facilitating a gradual migration. The move to Grafana Cloud also aligns with Kambi's future plans to potentially replace their existing Elasticsearch solution with Grafana Loki for enhanced observability and performance.
