Practical articles on AI, DevOps, Cloud, Linux, and infrastructure engineering.
We moved a 60-node production EKS cluster to Auto Mode. Some pain points evaporated, others got harder. The cost picture is more nuanced than the marketing suggests.
We've been running the OTel Collector at the edge of every cluster for 18 months. The config patterns that lasted, the ones we ripped out, and a few processors that quietly saved us money.
Blue/green is easy for stateless services. We did it for our primary Postgres cluster with 3.2TB of data and ~8k connections. Here's exactly how — and what almost went wrong.
We were drowning in 200 alerts a week. Most got ignored. After a quarter of triage and rework, we're at about 15 — and on-call actually responds to them.
We wrote pretty postmortems for two years and kept hitting the same incidents. Here's what changed when we started writing ugly ones.
A real walkthrough of shrinking bloated Docker images from 1.2GB to 240MB using multi-stage builds, Alpine, and dependency auditing.
A real-world multi-cluster traffic routing guide for SaaS teams that have outgrown a single Kubernetes cluster and need safer rollout control without a service-mesh science project.
A Kubernetes blue-green deployment guide built around a real rollout failure, showing the guardrails that matter when traffic shifting, health checks, and rollback timing all interact.
Practical game day scenarios for CI/CD: broken rollbacks, permission issues, and slow feedback loops—and how we fixed them.
Cut Kubernetes spend without hurting reliability using a practical FinOps playbook for rightsizing, autoscaling guardrails, showback, and weekly waste cleanup.
Understand Kubernetes networking: ClusterIP, NodePort, LoadBalancer, Ingress, and policy.
