• 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.

• We replaced etcd with Google Cloud Spanner. Here's what happened.

  Petr Petrenko

  This case study shows what happened when a team swapped etcd for Google Cloud Spanner, using commit timestamps instead of a single revision counter, so writes no longer queue behind each other.
