制限よ、さようなら。データよ、こんにちは。Qontoが ClickHouse Cloud でオブザーバビリティを再構築する方法

Qonto, a digital bank serving over 600,000 small businesses and freelancers in Europe, has significantly enhanced its observability capabilities by adopting ClickHouse Cloud, allowing comprehensive monitoring across its platform without sampling or cardinality constraints. Transitioning from Grafana Tempo to ClickHouse Cloud enabled Qonto to extend query timeframes from a few hours to two weeks, significantly compress high-cardinality data, and reduce storage costs, while integrating OpenTelemetry for semantics and leveraging AI to democratize incident investigation. This approach not only improved incident response times and accuracy but also allowed Qonto's teams to utilize data more effectively, facilitating a shift from a focus on mere infrastructure management to innovative use-case exploration. The integration of AI-powered tools, like the "incident companion," has empowered all employees, regardless of technical expertise, to efficiently query and analyze data, fostering a culture of continuous learning and improvement.
