Kafka on Kubernetes: Performance Lessons for Any Disk-Heavy Data Service
https://dev.to/yaakovamar/kafka-on-kubernetes-performance-lessons-for-any-disk-heavy-data-service-3bl5
We recently started migrating Kafka clusters from EC2 to EKS using Strimzi. As soon as we moved the first cluster, we saw persistent disk reads across the brokers and higher latency than we expected on comparable hardware.

Your AI just deleted the wrong deployment. Now what?
https://medium.com/@mirusser/your-ai-just-deleted-the-wrong-deployment-now-what-d9e3a03bf46c
Picture this. A developer asks an AI assistant to "scale down staging to save costs." The AI, helpful as always, executes: kubectl scale deployment critical-api --replicas=0 -n production. Wrong namespace. Right outcome, wrong cluster. The API is down.

Building a Real k6 Test Suite Against a Live Kubernetes App
https://dev.to/matthew_wimpelberg_79193b/part-2-of-4-building-a-real-k6-test-suite-against-a-live-kubernetes-app-1f81
In part 1 I covered k6's philosophy and the anatomy of a first test. This post is where things get real — a production-grade test suite running against a live microservices app on a homelab Kubernetes cluster, including what went wrong on the first run and how I debugged it.

We recently migrated our production GKE cluster from the traditional Ingress controller to the Kubernetes Gateway API — and honestly, we should have done it sooner.

При переходе к продакшен-нагрузкам важно заранее продумать отказоустойчивость, сценарии переключения между узлами и поведение кластера при плановых работах и сбоях.
29 сентября эксперт Cloud․ru проведет вебинар о том, как обеспечить высокую доступность PostgreSQL в облаке.
В программе:
▶ как устроен отказоустойчивый кластер в Evolution Managed PostgreSQL▶ где проходит граница между высокой доступностью и аварийным восстановлением▶ какую роль играет Multi-AZ-архитектура▶ для каких задач используются реплики PostgreSQL▶ как работают ручное и автоматическое переключение▶ что важно учитывать при эксплуатации PostgreSQL в продакшене
Будет интересно всем, кто работает с PostgreSQL и отвечает за доступность баз данных и надежность инфраструктуры.

Heroic saves are near misses

What doesn't usually happen is anyone asking: what if she hadn't been there? Because that heroic save, for all the heartfelt celebration around it, was actually a near miss from a systemic point of view.
