10m requests in 10 minutes for $0.0116, CPU Usage + Requests + Limits, Optimizing Resource Utilization, Threw away 13 years of work for EKS
2 Apr 2025
This newsletter is brought to you by LoftLabs — simplify Kubernetes with vCluster, the leading solution for Kubernetes multi-tenancy and cost savings
In the past month, we've partnered with LoftLabs on a free educational series on Kubernetes multi-tenancy. We delivered six webinars and covered networking, security, costs and more for multi-tenant clusters.
All the sessions and labs are available on demand, and if you sign up for the series, you will get an email with all the links.

Deep Dive into Kubernetes CPU Usage, Requests, and Limits
John Tucker
Kubernetes CPU performance isn't just about limits: in this article, you will learn how thread count, time-slicing, and CPU requests interact to prevent throttling and optimize container workload efficiency.
Optimizing Kubernetes Resource Utilization: CPU and Memory Requests and Limits
Alexander Ibrahim
Learn how to optimize Kubernetes resource utilization by setting appropriate CPU and memory requests and limits.
Discover how to use autoscaling and continuous monitoring to balance requests and limits, avoiding over-provisioning and under-provisioning.
We threw away 13 years of work for EKS
Andrew George
In this case study, you'll learn how GumGum, an ad tech company, migrated their 13-year-old EC2 infrastructure to Amazon EKS and the benefits they gained from the modernization.
Proxyless scale-to-zero with eBPF
Isala Piyarisi
You can achieve 'scale-to-zero' efficiency with eBPF and overcome KEDA's limitations.
eBPF intercepts requests at Layer 3, eliminating proxies and reducing latency & costs.

Code & tools
Multus CNI is a CNI plugin enables attaching multiple network interfaces to pods.
Typically, in Kubernetes, each pod only has one network interface (apart from a loopback).
With Multus, you can create a multi-homed pod with multiple interfaces.
Liqo: multi-cluster topologies
Liqo is an open-source project that enables dynamic and seamless Kubernetes multi-cluster topologies, supporting heterogeneous on-premise, cloud and edge infrastructures.
VolSync asynchronously replicates Kubernetes persistent volumes between clusters using either rsync or rclone.
It also supports creating backups of persistent volumes via restic.
Kube-vip: virtual IP and load balancer
kube-vip provides Kubernetes clusters with a virtual IP and load balancer for both the control plane (for building a highly-available cluster) and Kubernetes Services of type LoadBalancer without relying on external hardware or software.
Karpor: Kubernetes Visualization Tool
KusionStack
Karpor is a tool that brings advanced Search, Insight, and AI capabilities to Kubernetes, providing crucial visibility into Kubernetes clusters across any cloud.
