Our colleague, Denys Kondratenko, presented the talk FinOps: Cloud Billing and Usage with ClickHouse at the FroSCon 2025.
Managing costs and billing across numerous Cloud-managed Kubernetes clusters presents significant challenges. In this talk, we’ll explore these challenges and discuss solutions using ClickHouse, OpenCost, and how a unified FOCUS schema helps with it. Leveraging ClickHouse’s capabilities, we’ll demonstrate how it efficiently imports diverse Cloud billing data streams. Additionally, we’ll delve into how OpenCost addresses the complexities of real-time cost management within a multitenant architecture. Join us to uncover practical insights into optimizing cloud costs effectively
