Does Kubernetes cost money?
Worker nodes are priced at regular machine instance prices. So the total costs for running our cluster using GKE equals $30,874 (with sustained use discounts). When we apply the committed use discount for 70% of the worker nodes, the total Kubernetes cost equals $28,718.
