Gunicorn vs NGINX Explained

Web applications typically disseminate information via three server layers:

  1. Web server  - First layer: Receives request from client(web browser)
  2. Application server - 2nd layer: Receives requests from web server if the client is requesting dynamic content
  3. Database - 3rd layer: Receives database queries from web framework's request handler methods
In this example , nginx is the web server, gunicorn is the application server(interface between nginx and web framwork request handling function) and the database can be assumed to be a lightweight sqlite3 database.

Example: Django architecture


Alternatives to nginx:

  • Cherokee
  • Apache HTTP server



 Alternatives for gunicorn:

  • Apache
  • Mongoose
