This case study shows how a team ran one Kafka cluster stretched across three separate Kubernetes clusters with Strimzi, Submariner and Cilium, and kept it alive when a whole cluster went down

➤ ku.bz/h_X-GXdB5

This case study shows how a payments company rebuilt deployments around GitOps with Argo CD on Kubernetes, so every production change is a reviewed Git commit and PCI audits stop being guesswork

➤ ku.bz/rPwVfs6rD

This case study shows how to migrate from fragile EC2-based infrastructure to AWS EKS with GitOps using ArgoCD, Jenkins, and SonarQube for a URL shortening platform, achieving 80% faster deployments and self-healing infrastructure

➤ ku.bz/RGMgc_zBz

This case study shows how a nightly export job kept getting OOM-killed on Kubernetes, and how switching to streaming dropped its memory use from 700 MB to about 30 MB

➤ ku.bz/T5zphvrfJ

This article explains how the Kuadrant Console Plugin turns raw policy YAML into guided forms inside the OpenShift console, and how the form and YAML views stay in sync in both directions

➜ ku.bz/bZqvJv5VL

This case study shows how one engineer built k8s-rightsizer in four days and cut Kubernetes costs by 36%, by applying CPU and memory recommendations automatically

➤ ku.bz/k2P-c1P8V

This article lays out a GitOps reference architecture for running one app across 25 regions, where every region reconciles itself with Argo CD and a rollback is a git revert scoped to that region alone

➤ ku.bz/Szhjv5TwS

This case study shares how a team upgraded a production OpenShift cluster on IBM Cloud with Portworx replication in place, and which compatibility and worker-replacement checks kept it from turning into an outage

➜ ku.bz/fZr2FXszm

This tutorial shows how to chain KEDA cron scaling with Karpenter so non-prod EKS clusters drop to zero nodes at night and on weekends, cutting the compute bill by 65 to 85%

➤ ku.bz/J18t6k5N5

This article argues that uptime, latency and error rate only tell you a system is alive, not correct, and shows which behaviour-level signals and baselines belong in dashboards and alerts instead

➜ ku.bz/v09SHsxGG

This case study traces a 503 at the ingress back to a broken CNI overlay between nodes, even though every pod and endpoint looked healthy, and fixes it with topology spread constraints

➤ ku.bz/M-PjSd6Tl

This case study shows how a team gives every feature branch its own staging environment on Kubernetes, generating manifests in CI and letting an Argo CD ApplicationSet create and delete them

➜ ku.bz/FLNLH90vp

This article explains how to make Kubernetes spend traceable to each team, using a consistent label taxonomy, Prometheus recording rules on resource requests, policy enforcement and chargeback reporting

➤ ku.bz/w2TsnQRVb

This article walks through a real-time object detection pipeline where Kafka absorbs bursty camera traffic, YOLOv8 workers autoscale on Kubernetes, and MLflow tracks every model version

➜ ku.bz/vKPdn6ST4

Rune is a fast native macOS app for people who debug clusters every day, with unified pod logs, YAML editing with server dry-run, port-forwarding and a command palette

➤ ku.bz/zRfTn2ZwJ

This case study shares a production Strimzi Kafka setup that survives broker and zone failures, using KRaft instead of ZooKeeper, per-zone node pools, Cruise Control rebalancing and careful JVM tuning

➤ ku.bz/Jmj90fchK

This case study shows how Zalando moved over one million requests per second to in-process load balancing, kept caches warm during scaling, and saved more than $1,000 a day

➜ ku.bz/p9Lpdy2Hh

🗣️ Frédéric Gaudet explains the critical relationship between Kubernetes deployment strategies and Istio's warm-up feature effectiveness. Without proper rollout configurations, warm-up becomes completely ineffective
