I have a Flask application running on port 5001 on my remote Ubuntu 20.04 computer. I need to make sure that it can be accessed on the internet. My organization bought the domain name myapp.edu.
For the web server itself they told me to use Apache2 web server. I set up my Apache2 configuration without any mod_wsgi module and by just proxying the request addressed to https://myapp.edu:443 to https://my-IP-address:5001 and it works for now.
But after reading up on the internet on how to set up Python backend apps, I stumbled upon WSGI servers such as Gunicorn that sit between the web server and the application. I see them especially when deploying Django applications in conjunction with Ngnix webserver.
I feel uneasy about how I did my setup right now, without any explicit WSGI server. I don't know if it's the correct approach.
I have tried the approach I wrote above. The main reason I am asking this is that the website is accessible on my organization's network, but not outside the network. I was wondering if not having the WSGI application server inbetween is the issue.
