KubeCon EU 2024 Lightning Talk Understanding the cost and efficiency of Kubernetes on public clouds is essential once you start expanding your infrastructure with real production workloads. The FinOps Certified Solution and CNCF Sandbox OpenCost project monitors cloud costs and models current and historical Kubernetes cloud spend and resource allocation by service, deployment, namespace, labels, and much more. This data provides transparency for cloud bills and can be used as the basis for optimizing your Kubernetes deployments based on cost allocation. This quick introduction to OpenCost will start your foundation for monitoring and Kubernetes and cloud costs.
