Practical articles on AI, DevOps, Cloud, Linux, and infrastructure engineering.
A synthesis of this year's major industry surveys (Stack Overflow, GitHub Octoverse, CNCF, DORA, and more), with the actual numbers and what they mean for a working team.
A service mesh buys you mTLS, traffic control, and uniform telemetry, and costs you a new distributed system. What it does, when it earns its keep, and how Istio, Linkerd, Cilium, and Consul compare.
A practical, layer-by-layer checklist for securing Kubernetes clusters, workloads, networking, secrets, and the software supply chain.
A practical walkthrough to install Istio, turn on automatic mTLS, and run a canary traffic split on Kubernetes.
A practitioner's comparison of Cilium's eBPF, sidecar-less dataplane against Istio's Envoy sidecar and ambient mesh models.
A practitioner-grade breakdown of Istio and Linkerd across architecture, mTLS, traffic control, performance, and total cost of ownership.
A practical guide to AIOps and self-healing infrastructure: the maturity ladder from alert to autonomous remediation, observability as the foundation, anomaly detection, Kubernetes-native self-healing, an operator-driven remediation loop, agentic SRE, and the guardrails that keep automation safe.
A practical comparison of Kubernetes-native continuous reconciliation against the classic CLI-driven, state-file IaC model for platform teams.
CrashLoopBackOff, ImagePullBackOff, OOMKilled, Pending, NodeNotReady, CreateContainerConfigError, and failing probes, each with what it means, the command that diagnoses it, and the usual fix.
The ordered kubectl toolkit we reach for when a pod misbehaves, with the five commands we run first and what each one actually tells you.
Both run pipelines as CRDs inside your cluster, but they were built for different jobs. Here's how Tekton and Argo Workflows actually differ in practice.
A node flips to NotReady and pods start disappearing. Here's the order we check things in, the usual culprits, and how to recover without making it worse.
