<p>Cloud bills arrive and suddenly everyone wants answers. Who spent what? Why did costs spike last month? Platform teams often find themselves caught in the middle, translating cryptic infrastructure costs into something finance and engineering leads can actually understand. It doesn't have to be this painful.</p><p>This talk shares practical approaches to building cost accountability into Kubernetes platforms without creating friction or finger-pointing. It covers how to implement team-level cost allocation using labels and namespaces effectively, set up showback dashboards that engineering teams will actually check, create budgets and alerts that inform rather than annoy, and have productive conversations with finance that don't end in spreadsheet wars.</p><p>Drawing from real experiences across platform teams of different sizes, this session focuses on what actually works using open source tools like OpenCost, Prometheus, and Grafana. No expensive enterprise platforms required. No blaming developers for writing code that runs.</p><p>The goal is simple: make cost visibility a natural part of platform engineering instead of a quarterly fire drill.</p><p><strong>Attendee Takeaways:</strong></p><p>Learn labeling strategies that make cost allocation painless. Build a showback dashboard in Grafana that teams trust. Set up meaningful budget alerts using Prometheus. Navigate the platform team vs finance conversation with confidence.</p>
