Karpenter is a Node-based scaling solution built for K8S, and its goal is to improve efficiency and cost. It is a great solution because we don't need to configure instances types or create nodegroups, which drastically simplifies configuration. On the other hand, the integration with Spot instances is painless and we can reduce our costs (up to 90% cheaper than On-Demand instances)
A Kubernetes node autoscaling solution is a tool that automatically adjusts the size of the Kubernetes cluster based on the demands of our workloads. Because of this, we don’t need to create manually a new Kubernetes Node every time we need it (or delete it). Karpenter automatically provisions new nodes in response to unschedulable pods.
