Right Place, Right Size: Using an Autoscaler-Aware Multi-Cluster Kubernetes Fleet Manager for ML/AI Workloads

Introduction

Are you tired of juggling multiple Kubernetes clusters, desperately trying to match your ML/AI workloads to the right resources? A smart K8s fleet manager like the Elotl Nova policy-driven multi-cluster orchestrator simplifies the use of multiple clusters by presenting a single K8s endpoint for workload submission and by choosing a target cluster for the workload based on placement policies and candidate cluster available capacity.  Nova is autoscaler-aware, detecting if workload clusters are running either the K8s cluster autoscaler or the Elotl Luna intelligent cluster autoscaler.

In this blog, we examine how Nova policies combined with its autoscaler-awareness can be used to achieve a variety of "right place, right size" outcomes for several common ML/AI GPU workload scenarios. When Nova and Luna team up you can:

1. Reduce the latency of critical ML/AI workloads by scheduling on available GPU compute.
2. Reduce your bill by directing experimental jobs to sunk-cost clusters.
3. Reduce your costs via policies that select GPUs with the desired price/performance.
