The devops interview questions most hiring managers use were written for SaaS companies. They test knowledge of CI/CD pipelines, container orchestration, infrastructure as code, and incident response. A candidate who answers all of them well can still cause a slashing…
Chaos engineering Kubernetes tutorials cover the same experiments: kill a pod, inject network latency, simulate a node failure. Those experiments are valuable for stateless web applications. They are insufficient for blockchain workloads. A Cosmos validator or Ethereum consensus client that…
Kubernetes security best practices start with an uncomfortable truth: Kubernetes is not secure by default. A default installation allows pods to run as root, has no network segmentation between pods, stores secrets base64-encoded (not encrypted), and grants broad default service…
GitOps Kubernetes is no longer a pattern that forward-thinking teams adopt early, it is the default delivery model for production Kubernetes in 2026. GitOps adoption has reached 64% of enterprises as the primary delivery mechanism, leading to measurable increases in…
This helm chart tutorial takes you from zero Helm knowledge to deploying a production-ready application with multi-environment values, dependency management, hooks, and CI/CD integration. Helm is used by over 80% of Kubernetes adopters according to the CNCF annual survey, and…
Kubernetes cost optimization is the problem most tams reach for too late, after the AWS invoice lands at twice the expected amount and the CFO is asking questions that engineering cannot answer cleanly. The instinct at that point is to…
Agentic DevOps is the term for something that is already happening in production at a small number of organizations and being actively piloted at a much larger number: AI agents that do not just assist engineers but autonomously execute operational…
This docker kubernetes tutorial takes you from writing your first Dockerfile to running a production-grade deployment with autoscaling, health checks, and rolling updates. Most Docker Kubernetes tutorials stop at Minikube with a hello-world container. This one does not. The goal…
Platform engineering vs devops is one of the most consistently misunderstood distinctions in modern software engineering. Not because the concepts are complex, but because most explanations treat them as competing philosophies when they are actually sequential ones. DevOps came first,…
DevOps outstaffing vs in-house is a decision that most startups make badly, not because the analysis is complex, but because they make it at the wrong moment, with the wrong inputs. The typical pattern: a Series A startup with four…
