@SoftwareEngineer I thought it was one and the same question in several blocks, I clean it out and keep the part I need ! Thank for your response :) — Valensto 24 secs ago

There are billions of forums online. Search engines can be used to find articles etc, we're not a free do-my-research service, sorry. Depending on what your specific query is, there is a software engineering / architecture stack exchange. Check their on-topic guidance in case it's any more suitable there. — ADyson 36 secs ago
