Kubernetes Cluster Autoscaler vs Karpenter

Qovery has announced official support for Karpenter in all Managed AWS EKS clusters, highlighting its potential as a cost-effective alternative to the Cluster Autoscaler. While the Cluster Autoscaler adjusts Kubernetes cluster sizes based on resource availability and underutilization, Karpenter, launched by AWS, optimizes pod placement and reduces billing costs by automatically provisioning the necessary compute resources for Kubernetes clusters. Although both solutions have their merits, Karpenter is particularly advantageous for significant workloads, whereas the Cluster Autoscaler is more stable and widely used for production environments. Qovery considers Karpenter suitable for pre-production, staging, or testing phases, with the hope that other cloud providers will adopt it as a new standard in the future.
