Kubernetes faces challenges with efficient node autoscaling due to fluctuating workload demands, leading to either capacity shortages or cost inefficiencies. The Cluster Autoscaler offers a native solution, automatically adjusting the number of nodes based on demand, but it has limitations such as reactive scaling and lack of multi-cluster awareness. Karpenter improves upon this by providing faster, cloud API-driven provisioning without the need for static node groups, but it still lacks advanced spot orchestration and bin-packing capabilities. Harness CCM Cluster Orchestrator builds on Karpenter, offering advanced spot orchestration, dynamic workload splitting, and enhanced bin-packing, while also integrating with Harness’s Commitment Orchestration for cost optimization. This makes Cluster Orchestrator a more efficient and cost-effective solution by proactively managing resource utilization and providing out-of-the-box spot orchestration without additional configuration.
