• Kafka on Kubernetes: Performance Lessons for Any Disk-Heavy Data Service

  Jacob Amar

  This case study traces why Kafka started reading from disk after moving from EC2 to EKS, and lands on cgroup v2 reclaim pressure.

• 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.

• Autoscalable GitLab runners on AWS EC2

  Timur Nizamutdinov

  This tutorial shows how to replace always-on EC2 runners with autoscaling GitLab runners using the AWS fleeting plugin and an Auto Scaling Group, so instances start per job and shut down when the queue is empty.

• Kubernetes KEDA Autoscaling: Scale Smarter, Not Harder

  Dharmendra Yadav

  This tutorial shows how KEDA scales workloads on queue depth instead of CPU, with a full RabbitMQ example: install, TriggerAuthentication, ScaledObject and a load test that proves the scaling works.

• Building a Distributed Bot Detection PoC Using Nginx Logs, awk, and Terraform on GCP

  Parag Shahade

  This tutorial shows how to build a simple bot-detection system from Nginx logs and use GCP controls to investigate and slow suspicious traffic.

• Testing Go Microservices with Real Production Traffic Using GoReplay

  Imesh Herath

  This tutorial shows how GoReplay replays real production traffic in Kubernetes so you can test a new Go service before sending users to it.

• Vlan migration: moving a live Kubernetes cluster without downtime

  zolty

  This case study covers migrating a live k3s cluster from a flat network to a VLAN architecture, including an etcd quorum loss caused by moving too many nodes at once and the recovery steps using k3s server --cluster-reset.

• To Centralise or Not to Centralise: The Questions That Shaped the Kubernetes CODECO Federated Architecture

  Rute C. Sofia

  This article explains the centralise-or-not trade-off behind CODECO's federated Kubernetes architecture across cloud, edge and IoT, and how neighbourhood-scoped control, decentralised AI and federated scheduling answer it.

• The Illusion of CPU: Why HPA Fails for Pub/Sub Consumers and What to Do Instead

  Sujith K. Surendran

  This article explains why CPU is the wrong scaling signal for Pub/Sub consumers, since pods look healthy while the backlog grows, and argues for scaling on queue depth with KEDA instead.

• Go Fiber Benchmark Deep-Dive: Breaking 1 Million RPS on Apple Silicon

  Max Taylor

  This article explains how Go Fiber reached 1.16M RPS on Apple Silicon by running client and server benchmarks inside Docker Desktop's Linux VM to bypass macOS loopback TCP limits.
