People learn DevOps from docs and videos, but the real skill is debugging a broken system, and most engineers only get that practice in production, when the stakes are real. Setting up your own labs to break things on purpose takes VMs, cloud spend, and time. Who it’s for: 1.Freshers and career switchers with no production access 2.Engineers prepping for SRE or DevOps interviews, where troubleshooting rounds are common 3.Devs who want to get confident debugging Linux, Nginx, Docker and K8s
