Django is full of shortcuts to make web developers' lives easier, but all those tools are of no use if you can't easily deploy your sites. Since Django's inception, ease of deployment has been a major goal.
There are many options for deploying your Django application, based on your architecture or your particular business needs, but that discussion is outside the scope of what Django can give you as guidance.
Django, being a web framework, needs a web server in order to operate. And since most web servers don't natively speak Python, we need an interface to make that communication happen.
Django currently supports two interfaces: WSGI and ASGI.
You should also consider how you will handle static files for your application, and how to handle error reporting.
Finally, before you deploy your application to production, you should run through our deployment checklist to ensure that your configurations are suitable.
