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 today; field notes, cheat sheets 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.
Every tutorial series ships with its own interview-question set — real questions with worked answers, not a flashcard deck.
Real production war-stories — the cost cuts, the migrations, the 3am incidents — written up as decision guides, not marketing copy.
Quick-reference command and config pages per tool — kubectl, Terraform, AWS CLI — for when you already know it and just need the syntax.
“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 shipped, what's in progress, and what's planned next — updated as content ships, not on a fixed schedule.
Mohamed Salah, Principal DevOps Engineer — 8+ years across AWS, Azure and GCP, Kubernetes, observability and incident response.
