Kubernetes spend grows with idle capacity, oversized requests and expensive instance choices. Rightsizing and autoscaling recover most of it.
Reduce Kubernetes costs by buying cheaper capacity, running fewer idle nodes and sizing Pod requests to real usage, then trimming network and storage charges.
A request is the CPU and memory the scheduler reserves for a container. A limit is the most it may use. Requests decide placement and how many nodes you buy.
Clusters run idle because Pods request far more CPU and memory than they use. Rightsizing sets requests from measured usage so work fits on fewer nodes.
Kubernetes adds cross-zone traffic, NAT gateway processing, a load balancer per Service and public IPv4 fees. Same-zone routing and shared ingress cut them.
Stateless replicas, checkpointed batch jobs and CI runners suit spot nodes. Singleton databases, quorum systems and long jobs without checkpoints do not.
Bin packing places Pods on as few nodes as possible. The default scheduler spreads Pods instead, so nodes stay half empty until something consolidates them.
Usually not for latency-sensitive services. Always set CPU requests and memory limits, and add CPU limits only for fairness, Guaranteed QoS or repeatable tests.
