Most EKS clusters over-provision. Static node groups and the Cluster Autoscaler react slowly and force you into fixed instance types, so you pay for idle headroom and oversized nodes. Karpenter takes a different approach — it provisions exactly the right instances for pending pods in seconds, and removes them when they’re no longer needed.
SquareOps tunes Karpenter for cost and reliability together: diverse instance flexibility, safe Spot adoption with interruption handling, Graviton (ARM) where workloads support it, and tight bin-packing. Paired with our FinOps practice and SpendZero, that typically means 30–50% lower EC2 spend with faster scaling, not slower.
From a cost review to a tuned, Spot-and-Graviton autoscaling setup with guardrails.
We find where your spend leaks — idle nodes, oversized requests, on-demand where Spot would do — and quantify the savings.
Replace static node groups with Karpenter provisioners tuned for flexibility, consolidation, and fast scale-up.
Capture the biggest savings safely — diversified Spot with graceful interruption handling and ARM/Graviton where it fits.
Keep savings durable with budgets, cost visibility, and policies — backed by our SpendZero cost platform.
A safe path to just-in-time autoscaling that cuts spend — tuned for reliability and aligned with your wider Kubernetes cost optimization on EKS.
We review your node groups, workloads, and spend to size the opportunity.
We design provisioners, instance flexibility, and Spot/Graviton strategy.
We deploy Karpenter, migrate workloads, and add interruption handling.
We hand over guardrails and train teams to manage provisioners safely.
Optional managed support tunes bin-packing and tracks ongoing savings.
Karpenter watches pending pods and the live cluster, then provisions and consolidates capacity to match demand precisely.
Karpenter sees unschedulable pods and reads their exact CPU, memory, and constraints.
It launches the cheapest suitable instance — Spot, Graviton, right-sized — in seconds.
As load drops, it bin-packs workloads onto fewer nodes and terminates the rest.
Disruption budgets and interruption handling keep consolidation and Spot safe for production.

Our published Graviton4-on-EKS benchmark quantifies the price/performance gains of moving compatible workloads to ARM.
Migrated to Karpenter with diversified Spot and consolidation, cutting EC2 cost while improving scale-up time.
SpendZero continuously flags idle and oversized resources, keeping the savings from drifting back over time.
"Working with SquareOps has been a great experience — their AWS DevOps engineers are highly skilled and consistently deliver strong results."
Karpenter and AWS-native capabilities, backed by our own FinOps tooling.
We optimise cost and reliability together. Savings that page your on-call at 2am aren’t savings — our guardrails make them durable.
We tune Spot diversification and disruption budgets so savings never come at the price of uptime.
We benchmark and migrate compatible workloads to ARM for real price/performance gains, not guesswork.
SpendZero’s 37+ waste checks and budgets stop savings from quietly eroding over time.
Ongoing optimisation and on-call coverage so the cluster stays cost-efficient and healthy.
