Why can't you use Django's runserver in production, and what should you use instead? प्रोडक्शन में Django के runserver का उपयोग क्यों नहीं कर सकते, और इसके बजाय क्या उपयोग करना चाहिए?

Django's development server (manage.py runserver) is explicitly single-threaded by default, unoptimized for performance, and lacks the security hardening, connection handling, and process management needed to serve real traffic — the Django documentation itself warns it must never be used in production.

Production deployments use a dedicated WSGI application server such as Gunicorn or uWSGI to run the Django application with multiple worker processes handling requests concurrently, typically placed behind a reverse proxy like Nginx that handles TLS termination, serves static files efficiently, and buffers slow client connections before they reach the application workers.

gunicorn myproject.wsgi:application --workers 4 --bind 0.0.0.0:8000
