KubeCon + CloudNativeCon Europe 2025 · Session
In the dynamic landscape of cloud-native environments, managing costs effectively has become as critical as ensuring robust security. This talk, "Beyond Security: Leveraging OPA for FinOps in Kubernetes," delivered by Sathish Kumar Venkatesan at KubeCon EU, explores a paradigm shift: utilizing the **Open Policy Agent (OPA)**, a tool traditionally associated with security and compliance, to implement robust **FinOps** practices within **Kubernetes** clusters. Venkatesan argues that by extending OPA's capabilities, organizations can proactively govern cloud spend, optimize resource utilization, and foster a culture of cost accountability.

Venkatesan delivers a highly practical and technically sound presentation on extending Open Policy Agent (OPA) beyond traditional security use cases to implement robust FinOps practices in Kubernetes. By leveraging OPA Gatekeeper as an admission controller, organizations can proactively enforce cost-saving policies, prevent overprovisioning, and integrate with real-time cost data for dynamic budget enforcement. This isn't just theory; it's a clear roadmap with concrete Rego examples and a compelling demo, offering significant actionable insights for anyone wrestling with Kubernetes cloud…
