Kubernetes can be expensive if not managed properly. Here are proven strategies to reduce your K8s spend:
Right-Sizing Resources
Use Vertical Pod Autoscaler (VPA) to automatically adjust CPU/memory requests based on actual usage.
Spot Instances for Fault-Tolerant Workloads
Run batch jobs, CI runners, and stateless services on spot instances for up to 90% savings.
Cluster Autoscaler + Node Pools
Use different node pools for different workload types. Scale down idle nodes automatically.
Monitor & Alert on Cost per Namespace
Implement chargeback/showback with tools like Kubecost or CloudZero to drive accountability.
