Building reliable automatic gateway failover for critical infrastructure recovery access. How naive health checks broke everything, and why a 30-second stable recovery is better than a 5-second flapping failover. »
Kubernetes HPA with CPU metrics fails for queue-based workloads. Learn why queue depth is the right signal, how KEDA makes event-driven autoscaling trivial, and the configuration that reduced processing latency from 45 minutes to 5-15 minutes with zero manual scaling. »
Security patches can’t wait, but unplanned reboots break production. The update runbook for Debian, FreeBSD, and OpenBSD — with real scripts, hold patterns, and a zero-downtime cluster update sequence. »
Production machine learning requires more than training good models. This guide covers building a complete MLOps system with Kubernetes, Prometheus monitoring, and automated accuracy checks to catch model drift and prevent silent failures in production. »
