In the world of Kubernetes, resource management is more than just creating, deleting, or updating objects. It's an intricate dance involving numerous tools, operators, and users. As our infrastructure grows, it becomes increasingly challenging to maintain control, necessitating the adoption of more advanced and sophisticated resource management and control systems and approaches. In this article, I will not delve into the basic methods of creating resources, as that is a rather trivial task. Instead, I would like to share my experience in optimizing resource update paths, which have proven to be immensely valuable in managing resources within large and complex Kubernetes clusters, as well as during the development of operators.https://hackernoon.com/battle-for-resources-or-the-ssa-path-to-kubernetes-diplomacy
Are your Kubernetes applications inexplicably slowing down, even when your nodes seem to have plenty of CPU to spare? You might be experiencing CPU throttling. I recently watched an excellent CNCF video by Dave Chiluk, an engineer at Indeed. This article has some of my takeaways from the video.https://www.kubeblog.com/blog/understanding-and-fixing-cpu-limits-in-kubernetes
The Kubernetes NodeSwap feature, likely to graduate to stable in the upcoming Kubernetes v1.34 release, allows swap usage: a significant shift from the conventional practice of disabling swap for performance predictability. This article focuses exclusively on tuning swap on Linux nodes, diving into the critical Linux kernel parameters that govern swap behavior and how they influence workload performance, swap utilization, and eviction mechanisms.https://kubernetes.io/blog/2025/08/19/tuning-linux-swap-for-kubernetes-a-deep-dive
Kubernetes is powerful, but troubleshooting issues in a live cluster can be painful. In a complex deployment, critical warning signs often hide in thousands of log lines and events. What if we could surface these reliability issues before they take applications down?https://prequel.hashnode.dev/how-i-find-and-fix-kubernetes-exit-codes-and-misconfigurations-for-free
Istio is a foundational piece of our architecture, which makes ongoing maintenance and upgrades a challenge. Despite that, we have upgraded Istio a total of 14 times. This blog post will explore how the Service Mesh team at Airbnb safely upgrades Istio while maintaining high availability.https://medium.com/airbnb-engineering/seamless-istio-upgrades-at-scale-bcb0e49c5cf8
Kubernetes networking doesn't have to be a black box. This guide breaks it down, starting from the fundamentals of Linux networking and container isolation. We then dive into the complete Kubernetes model, explaining everything from Pod IPs and CNI plugins to Services, NetworkPolicy, and Ingress, providing a clear end-to-end map of how connectivity works in your cluster.https://www.lucavallin.com/blog/kubernetes-networking-from-packets-to-pods

Sveltos is a Kubernetes add-on controller. It deploys and manages add-ons and applications across many clusters using label-based matching. Sveltos does not compete with GitOps controllers like ArgoCD or Flux. Instead, it extends their capabilities. A GitOps controller monitors a repository and syncs manifests. In contrast, Sveltos takes these manifests and applies them across the entire fleet. Its configurations are cluster-agnostic; they do not reference a specific cluster. Instead, they target clusters by labels, which means when a new cluster joins the fleet, it requires no configuration changes, only the right labels. One configuration can serve any number of clusters that meet the defined criteria.https://github.com/projectsveltos
Ingress2gateway helps translate Ingress and provider-specific resources (CRDs) to Gateway API resources. Ingress2gateway is managed by the Gateway API SIG-Network subproject.https://github.com/kubernetes-sigs/ingress2gateway

ORAS is the de facto tool for working with OCI Artifacts. It provides CLI and client libraries to distribute artifacts across OCI-compliant registries.https://oras.land
Cluster API (CAPI) is an open-source Kubernetes sub-project. Its goal is to bring Kubernetes-style, declarative APIs and controllers to the problem of bootstrapping, configuring, upgrading and operating entire Kubernetes clusters, treating clusters themselves as first-class Kubernetes resources rather than as external, manually-provisioned infrastructure.https://itnext.io/build-your-own-managed-kubernetes-service-on-proxmox-with-capi-8d9786644818
The Kubernetes ecosystem is undergoing a significant transformation in how it handles networking, shifting from traditional Ingress API and annotations to the more advanced Gateway API.https://blog.nginx.org/blog/migrating-from-nic-to-ngf
In Kubernetes clusters, GPUs are expensive. Really expensive. And when your data science team is fighting over GPU resources like it’s Black Friday at Best Buy, you know something’s broken. That was the challenge I faced a few years ago. I implemented this solution back then, and though it’s been a while, I thought now would be a great time to share the experience. We had a k8s cluster with 8 NVIDIA A100 GPUs, and our data scientists were… unhappy. Small model training jobs waited hours for GPU access while large distributed training jobs hogged entire GPUs at 30% utilization. The culprit? GPU allocation granularity. Kubernetes treats GPUs as atomic resources, you either get a whole GPU or nothing. There’s no middle ground. I needed to fix this. And the solution wasn’t what I expected.https://medium.com/@nscharan1/gpu-starvation-in-kubernetes-how-dynamic-mig-partitioning-saved-our-gpu-budget-d242d6e56581
In Amazon Web Services, each instance type has a different upper limit on how many Pods it can run. For example, an m5.large instance can only run 29 Pods, but an m5.4xlarge can run up to 234. The reason is that each EC2 instance can only have a limited number of IP addresses assigned to it.https://medium.com/@mohamed.elmasary123/optimizing-pod-ip-allocation-in-aws-eks-with-amazon-vpc-cni-prefix-delegation-07d99004fdc2
