• How I Built a Kubernetes Rightsizer in 4 Days During Easter Vacation — and Cut k8s Costs by 36%

  Mcpunzo

  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.

• 503 at the Ingress: Debugging a Kubernetes Cross-Node Network Failure

  Karim Mirzaguliyev

  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.

• Kafka without ZooKeeper: My Strimzi HA Playbook on Kubernetes

  Dmitriy Shmatov

  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.

• Running ServiceNow’s MID Server on Kubernetes (and Tricking It Into Using IRSA)

  Ron Matsliah

  This case study shows how a team ran ServiceNow's MID Server on EKS as a StatefulSet and faked the EC2 metadata service so the agent would accept IRSA credentials.

• Zero-Day Runtime Isolation for Containers: Rethinking Dependency Trust

  Francesco Vitullo

  This article asks what a container can block on its own when a dependency turns malicious, and tests nono, a capability-based sandbox that limits file and network access at runtime.

• Scaling Kubernetes Deployments to multiple Regions: A GitOps Reference Architecture

  Vtulasinadh

  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.

• Leaked Kubernetes Secrets: Impact Assessment and Mitigation Strategies

  Dwayne McDaniel

  This article explains what an attacker can really do with leaked Kubernetes credentials, from kubeconfigs to service account tokens, and how to check the blast radius and shut it down.

• Distributed Consensus at Scale: Running Zookeeper on GKE with Local SSD (Z4D)

  Anuj Ashok Potdar

  This article explains how running ZooKeeper on Google Cloud Z4D nodes with local SSDs removes the disk latency that slows consensus writes, plus the GKE anti-affinity, volume binding and JVM tuning it needs.
