Scaling Kubernetes Workloads with Node Swap

Memory is often the first hard limit a Kubernetes cluster hits. Nodes run out of RAM long before they run out of CPU, and the new wave of agentic AI workloads makes this worse. These workloads demand large memory footprints to start up and run untrusted code, then sit idle waiting for the next prompt. That idle but resident memory is expensive, and it caps how many pods a node can hold. This is where swap helps. Kubernetes support for running nodes with swap enabled reached General Availability in v1.34, and by backing that swap with fast NVMe solid state drives (SSDs), a node can page out do…
