Why do you need to deploy a Flask project if it already works through www.mysite.com:5000?

Answer 1

At 5000, a development server is deployed. It is slow, unsafe, inferior. If you make 100 requests to it at the same time, they will be processed one after the other sequentially.
If you do it wisely - run the application server (uwsgi,) in several threads and put nginx in front of it, distributing requests among these threads (workers), you will get a much faster, more flexible and reliable system.
