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

Python packages

A python package is a collection of python module s. These modules are python scripts with *.py file extension. Typically, these scripts will contain python functions, classes, custom data types etc. Looking at the figure above, the Game package consist of an _init_.py file together with 3 other sub-packages Sound, Image and Level respectively. The _init_.py file must be included inside a directory for it to be considered a python package.In addition, the directory must be defined inside sys.path. Example usage: 1. import Game.Level.Start Suppose the start.py module consists of a function called mince() Inside your python application, you would need to call it as follows 2. Game.Level.Start.mince(<input_params>) Alternatively, you can reference it as follows 3. from Game. Level import Start     // recommended approach 4. Start.mince(<input_params>) A less common method is calling the function as if it was defined inside your curr...
