Reduce Amazon EKS cost: Coral rebalances workloads, nodes and clusters autonomously, without any downtime. Kubernetes cost optimization for platform, DevOps and FinOps teams, with no application code changes.
Coral is a Kubernetes cost optimization platform that continuously identifies and removes unnecessary infrastructure capacity while keeping workloads running. Built for Amazon EKS, Coral provides visibility into Kubernetes resource utilization, identifies waste, recommends right-sized workloads and optimizes node capacity based on actual demand.
Coral helps engineering and platform teams reduce Kubernetes infrastructure costs without application code changes. It continuously monitors workloads and nodes, provides actionable optimization recommendations, and automates safe capacity optimization while maintaining workload availability. Coral works alongside native Kubernetes autoscaling capabilities and supports environments using Karpenter, Node Auto Provisioning and Cluster Autoscaler.
With Coral, teams can understand where Kubernetes spend is going, identify unused capacity, optimize CPU and memory requests, and reduce unnecessary node capacity while maintaining operational visibility and control.
Highlights
Monitoring and recommendations: each Amazon EKS cluster's running cost today, its cost at the optimum and what you can recover, at AWS list price, with the CPU and memory each workload needs and the nodes you don't need.
Workload and node optimization: Coral rebalances your workloads and nodes autonomously, without any downtime. CPU and memory requests are set to what each workload really uses, and the nodes you don't need are removed. No application code changes.
Works with AWS: Amazon EKS with your Karpenter or Cluster Autoscaler, plus your Horizontal Pod Autoscaler and KEDA. Connect a cluster with one command, the Helm chart or the Terraform module. You stay in control: workloads are resized only after you switch on "Automatically optimize".
AWS Marketplace now accepts line of credit payments through the PNC Vendor Finance program. This program is available to select AWS customers in the US, excluding NV, NC, ND, TN, & VT.
This listing has one pricing dimension: Free. You pay nothing to use the product on Amazon EKS. There are no tiers, usage charges, or quantity options to configure. The single Free dimension covers all usage. The product right-sizes container CPU and memory requests and drains spare nodes so your autoscaler can remove them. Cost monitoring stays on, while workload sizing starts only after you switch on automatic optimization. If you later agree to paid terms, those details appear in your order or marketplace purchase.
Top-of-mind questions for buyers
What does the Free dimension cover, and what does billing cover if I later agree to paid terms?
The Free dimension covers all usage on Amazon EKS at no software charge. There are no unit counts to track. If you later agree to paid terms, the price, billing period, and payment terms appear in your order or marketplace purchase. You still pay your own AWS compute costs separately.
Does running the product add charges based on cluster size, nodes, or workloads?
No. The software dimension stays Free regardless of how many nodes or workloads you connect. One command connects a cluster, and the agent reads its nodes and workloads with no code changes. Cost monitoring runs always; workload sizing starts only after you switch on automatic optimization. Node optimization starts at install.
Will using this product change my AWS compute bill, and how is that saving measured?
The product right-sizes requests and empties spare nodes, so your autoscaler can remove them and cut your AWS compute spend. Savings are figured at your cloud's published list price for the region, with spot nodes at the spot rate and a 730-hour month. Discounts, reservations, and savings plans are left out.
