How to avoid errors when setting up a server?

Question

Python

Prompt articles or tutorials on the correct configuration of the frontend and backend server.
Nginx will serve as a frontend to avoid performance drops when working with blocking requests - thread pools built into it. For quick work with the database - asyncpg.
Additional server logic will be written in python (pypy). To speed up server calls - uvloop.

Please correct me if I messed something up with the "scheme" of the server part somewhere.
I don't want to make rookie mistakes. I would like to use the possibilities of these technologies optimally. Thanks

Googled 10 manuals for setting up the front, then 10 for setting up the back. Read it, sift it out, highlight the right moments for yourself. Do a basic setup of all services, make sure it works. Then tune until redness of the eyes.
