Choosing the right nodes for your specific environment is challenging, and requires repetitive, time-consuming tasks to maintain lean clusters.

  • How can you adjust the size of your instances dynamically when more workloads are deployed?
  • Will a new deployment affect previous measurements for resources and requests?
  • Are we setting requests and limits at optimal levels?

Tools like  Kubernetes Instance Calculator can help you estimate your costs and compare options, but the results lack the precision needed for right-sizing production clusters.

Using these suggested values can lead to oversizing your nodes and wasting your cloud budget, or worse, under-sizing your environment causing un-schedulable or crashing pods due to unforeseen runtime constraints.

With PerfectScale's data-driven insights, you can select nodes based on your real resource needs, optimizing your infrastructure utilization and reducing your overall node counts.

With PerfectScale you will: 

  • Quickly identify idle and unused resources throughout your node groups
  • Autonomously right-size your workloads to improve bin packing and reduce wasted resources
  • Improve the performance and efficiency of your Node-Autoscaler, like Karpenter
  • Size your nodes for peak performance at the lowest possible cost 

Selecting the right nodes is the key to maintaining a lean and performant cluster. Sign up today and start optimizing efficiently and eliminate guesswork today!

FAQ

  1.  What is PerfectScale?
    PerfectScale is an automated Kubernetes cost optimization and management platform. It's the industry's only production-ready automation platform that can safely and autonomously right-size your environment to enhance resilience and availability, eliminate waste, and reduce carbon emissions. With PerfectScale you can ensure your environment is always perfectly scaled to meet demand by effortlessly optimizing every layer of your K8s stack. 

  2.  What is PerfectScale Infrafit?
    PerfectScale’s Infrafit provides a granular view into the resource allocation to the various nodes and VM instances supporting your Kubernetes clusters. This gives organizations over-time visibility into the idle (unused) resources in each node group, presenting large cost savings opportunities to select nodes that more optimally support your cluster's needs.

  3.  Why Karpenter and auto-scaler don't guarantee optimized Kubernetes nodes?
    While Karpenter and Cluster Autoscalers can help scale your cluster, over-provisioned CPU and Memory requests severely impact their efficiency. To get the most out of Karpenter, and other node autoscalers, PerfectScale continuously and autonomously optimizes every workload in your environment to improve bin packing and to ensure new nodes are only added when they are actually needed.
