Practical articles on AI, DevOps, Cloud, Linux, and infrastructure engineering.
Unify traces, metrics, and logs with OpenTelemetry. Instrumentation, sampling, and backend-agnostic pipelines.
We upgraded a 60-node EKS cluster from 1.27 to 1.31 over six months. Four minor versions, one bad surprise, zero customer impact. Here's the playbook.
The Argo CD patterns that held up under real traffic: repo layout, sync policies you can trust, secrets that stay out of git, and the anti-patterns we stopped repeating.
Practical ways to cut Kubernetes spend: rightsizing, spot/preemptible nodes, and FinOps practices.
Why IDPs are core to modern DevOps. Self-service, standardized CI/CD, and better developer experience.
Practical game day scenarios for CI/CD: broken rollbacks, permission issues, and slow feedback loops—and how we fixed them.
We replaced 47 percentile threshold alerts with 3 SLO burn-rate alerts. The on-call rotation gets paged less and catches more.
We expanded from one Kubernetes cluster to four across two regions. The traffic-routing layer was the hardest piece. Here's what we tried, what worked, and what we'd do again.
We had Datadog for app metrics, Loki for logs, and zero useful insight into what our LLM service was actually doing. Here's the observability stack we built specifically for model serving.
HPA, VPA, and Cluster Autoscaler / Karpenter solve overlapping problems badly when you don't understand which one owns what. The mental model that keeps them from fighting.
We run a fleet of LLM agents on Kubernetes. They're stateful, bursty, and expensive — none of which K8s defaults are good at. Here's what we changed.
