This article opens up Xatastor, the storage system Xata built for millions of Postgres databases, explaining why they chose ZFS zvols over NVMe-oF instead of Ceph or Longhorn, and how their Kubernetes operator drives it.
Vakeesh Moorthy
This article describes the architecture behind a self-hosted cloud IDE, where each developer workspace is an isolated container on Kubernetes, requests are routed to small or large models by task, and clusters are spread across regions.
Braulio Dumba
This article presents a three-layer tenant isolation design where each tenant gets its own control plane, VM nodes and isolated network via KubeFlex, KubeVirt and OVN-Kubernetes, with latency measurements.
Anastassios Nanos
This case study shows how etcd CrashLoopBack pods on a Karmada/k3s demo cluster turned out to be a ZFS I/O latency problem, and how four ZFS tuning settings fixed it — including the exact etcd Prometheus metrics to watch.
Tools and utilities
booter is a small container that PXE-boots Talos machines on the same subnet, and can pass Omni kernel arguments so new nodes register with your cluster automatically.
ModelExpress is an NVIDIA service that manages model weights across a cluster, caching them and moving them GPU-to-GPU over RDMA instead of reloading from storage, so new vLLM or Dynamo pods start serving much sooner.
IncidentFox automates incident investigation with AI agents using 178+ tools for Kubernetes, AWS, and Grafana, featuring RAPTOR knowledge base for runbooks, alert correlation reducing noise by 85-95%, and Slack/GitHub/PagerDuty integrations.
MAAS (Metal-as-a-Service) is a production-grade tool that automates provisioning, network config, and OS installs (Ubuntu, CentOS, Windows, ESXi) across physical servers using PXE, IPAM, and full API-driven workflows.

Alex
This case study explains how one private container registry was shared across six AKS clusters in three regions.
It covers ACR geo-replication, image pull reliability, network access, permissions, and operational breakages.
Aadhith
This case study shows how CoreDNS became an EKS bottleneck under heavy DNS traffic and uses kube-burner test results to explain why NodeLocal DNSCache helped.
Groww Engineering Team
This case study explains how Groww built an internal chaos engineering platform on Kubernetes to run controlled failure drills like network faults, dependency outages, and traffic replay before real incidents hit production.
In this blog post, the author tracks down persistent sandbox-cleanup errors in a Kubernetes cluster, finds that zero-length CNI cache files cause the problem, and shows how manually deleting those files cleared the error.

Nahuel Aldrey
This tutorial shows how to automatically create and scale GitHub Actions runners on Kubernetes using Argo CD ApplicationSets that read config files from Git and deploy runner pods with custom resources and autoscaling.
Jeff Rescignano
This tutorial shows how to advertise Kubernetes LoadBalancer IPs to a LAN by configuring Cilium BGP Control Plane, an IP pool, Cilium BGP resources, and FRR on a UniFi Gateway.
Kenrick Tandrian
This tutorial explains why standard GKE Ingress breaks under Istio STRICT mTLS and shows how to replace it with an Istio Ingress Gateway, Gateway resource, and VirtualService.

This article explains how Kubernetes pod DNS failures can come from the default ndots:5 setting and a Linux conntrack issue, and shows how ndots:2 plus single-request-reopen can reduce DNS noise and fix intermittent resolution errors.
Mateen Ali Anjum
This article explains how to control runaway GPU spend in Kubernetes by adding taints, quotas, labels, Prometheus rules, and admission controls so teams can see who is using expensive GPU workloads and why.
Federico Iezzi
This article explains why low GPU utilization during LLM inference can be normal by breaking down prefill, decode, memory bandwidth limits, batching, and GKE B200 benchmark numbers.
Pavel Buchnev
This article teaches how to build self-evolving AI systems using Kubernetes, Temporal workflows, and automated deployment pipelines, enabling AI agents to detect errors, fix code, and redeploy services without manual intervention.
