It watches your cluster, notices that the workload fits on cheaper capacity, and rearranges the nodes to match. On a fleet running mostly spot, the savings are real and continuous — when I went through <a href="https://artazar.pages.dev/blog/04-cutting-the-eks-bill/" >the cost optimisation exercise</a>, it was one of the few changes that measurably moved the bill.</p> <p>It is also a machine that deliberately deletes your nodes, all day, forever. If your workloads aren&rsquo;t ready for that, consolidation turns into a steady drip of alerts that eventually teaches everyone to ignore the alerting channel — which is a worse outcome than paying for the oversized nodes.</p>
