• When ETCD Crashes, Check Your Disks First: A Pod CrashLoopBack Debugging Story

  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.

• Zero-Downtime EKS Migration: Production-Grade Kubernetes at Scale

  Krishnakanth E

  This case study explains how an ECS workload was migrated to EKS across two AWS regions with zero production downtime.

  It covers KEDA autoscaling, HashiCorp Vault, IRSA, disaster recovery, and a coordinated production cutover.

• We’re a 3-person tech team running production Kubernetes — So we built an AI SRE

  Leo Blondel

  This case study shows how a 3-person team built a Claude-based AI SRE that triages SigNoz alerts, checks Kubernetes, GitLab, logs, traces, and Slack, then ignores noise, escalates, or runs safe fixes.

• How We Set Up One Private Container Registry for 6 AKS Clusters Across 3 Regions and What Broke Along the Way

  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.

• Engineering End-to-End Observability for Kubernetes Workloads

  Pruthvi Raj Seknametla

  This article explains why Kubernetes observability falls apart when metrics, logs and traces don't share context, and how consistent service identity, bounded label cardinality and OpenTelemetry pull them back together.

• The feedback loops behind Kubernetes

  Fatih Arslan

  This article explains Kubernetes operators as feedback controllers, connecting reconciliation, informers, queues, spec/status, and self-healing behavior to database operations.

• Inside Xatastor: ZFS + NVMe-oF for millions of Postgres databases

  Claudiu Dascalescu

  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.

• Kubernetes Through Control Theory Glasses: HPA

  Myroslav Vivcharyk

  This article reads the HPA as a proportional controller from control theory, showing why the deadband, high gain and slow response trade-offs are unavoidable, and what dead time and pod quantization do to a PID version of it.
