You mean using nginx as a replacement for apache, correct?
Correct. Apache is often replaced with nginx/lighttpd when you don't
need features like kerberos, WebDAV, ...

So the application is written in aiohttp, I'm pretty sure I can make it run as a
systemd service but I have no experience of gunicorn.
Would you advice for it? Does it bring us much?
Depends on how much load do you expect on mdapi. I haven't done any
testing performance wise so I can't tell if it's actually worth. I would
say try it as there's not much difference in effort required for running
an app with apache/wsgi compared to nginx/gunicorn. nginx/gunicorn
configuration is quite easy, I would say even easier now (no supervisord
required) than apache/wsgi.
