SUMMARY:The Hidden Cost of Managed Kubernetes and How to Run Production-Grade Clusters for 1/10th the Price
DESCRIPTION:Most teams assume production-grade Kubernetes requires a managed service. The real cost of that assumption shows up in the invoice: control plane fees, per-GB egress charges, storage markups, and load balancer surprises that collectively push an 8-node cluster to about $4000 month on AWS, Azure, or GCP. This talk works through the full TCO breakdown in terms of compute, egress, storage, managed control plane, and IP addressing, with price comparison across all major clouds, and shows how the same production-grade setup runs for under $400/month on bare metal using entirely open source tooling. The second half is architectural and practical: what “professional” Kubernetes actually requires – HA control plane, GitOps with Argo CD, Cilium CNI, Sealed Secrets, Prometheus, cert-manager, Cluster API, how these components fit together in a management and workload cluster topology, and how KubeAid (an AGPL-3.0 open-source project) with its companion CLI automates the full cluster lifecycle from a single YAML config. The session closes with a live demo bootstrapping a production-ready cluster end-to-end within a few minutes.\n
