 The Horizontal Autoscaler API is flexible to any and all of these options. However, many Kubernetes users don’t rely on one of these mechanisms for node group management, instead relying on cloud provider specific abstractions (e.g. ASG). Therefore, we will introduce a resource that can be optionally targeted by HorizontalAutoscaler’s scaleTargetRef for users who don’t have a KRM node group concept. This is a stop gap until other node group representations become more widespread. This object will follow a cloud provider model to provide implementations for different cloud provider solutions such as EKS Managed Node Groups, EC2 Auto Scaling Groups, and others. The only field supported by this resource is replicas, leaving management responsibilities like upgrade up to some other controller.

 Queue-based node autoscaling and pending pods are both viable approaches with different trade offs. Pending pods is aligned with Kubernetes bin-packing principles, and yields increased capacity utilization for clusters that host diverse workloads and are overprovisioned. In this case, new pods will first schedule into existing capacity before forcing node group scale up via a pending pod autoscaler. However, if users are looking for a simple batch processing workflow of scaleup → do work → scale down, the bin-packing benefits must be weighed against pending pods’ complexity, scalability, and scheduling latency tradeoffs.
