A growing, free tutorial library for engineers learning DevOps, SRE and Platform Engineering — written by a Principal DevOps Engineer, tied to real production tradeoffs rather than certification-exam trivia. Tutorials, presentation decks, cheat sheets, quizzes, and interview prep today; field notes and decision guides on the way — see the roadmap below.
Deep, multi-part series — real production depth, not a syntax refresher. Kubernetes, AWS/GCP/Azure, observability, incident response, databases and more.
Course review decks built from the tutorial library — modern HTML slide presentations for quick recall, teaching, and interview prep refreshers.
Topic-based quizzes — Git, Docker, Kubernetes, Terraform, CI/CD, observability, FinOps and more — open recall, multiple choice, fill-in-the-blank, ordering, matching, log analysis and more, plus a mixed random round pulling from every topic at once.
Quick-reference command and config pages per tool — kubectl, Terraform, AWS CLI — for when you already know it and just need the syntax.
Real interview questions across DevOps, SRE, and Platform Engineering domains — no multiple choice. Every answer is coached: how to structure your response, a full example answer, and what interviewers are listening for. Practice one domain, or mix several to match the job you're applying for.
Real production war-stories — the cost cuts, the migrations, the 3am incidents — written up as decision guides, not marketing copy.
"X vs Y" with real tradeoffs from having run both in production — ECS vs EKS, Kong vs Traefik, and more.
Every DevOps/SRE term defined once, cross-linked from every tutorial that uses it.
What's in progress and what's planned next — updated as content ships, not on a fixed schedule. Shipped items move here off the list, not onto it — see the pillars above for what's live.
Mohamed Salah, Principal DevOps Engineer — 8+ years across AWS, Azure and GCP, Kubernetes, observability and incident response.
