What do you understand by CGI and WSGI?
WSGI is used for common tasks so it keeps the process around. CGI is for uncommon tasks so the process only runs when needed.
Is Django a WSGI?
Django’s primary deployment platform is WSGI, the Python standard for web servers and applications. Django’s startproject management command sets up a minimal default WSGI configuration for you, which you can tweak as needed for your project, and direct any WSGI-compliant application server to use.
Why do we need WSGI with Django?
WSGI is a protocol, it’s a standard of communication between a web server and a web application. Basically, between Gunicorn and Flask or Django. The web server should know how to speak to the web application, and the web application should know how to respond to the web server.
What is FastCGI Django?
Deprecated since version 1.7: FastCGI support is deprecated and will be removed in Django 1.9. The Web server delegates the incoming Web requests (via a socket) to FastCGI, which executes the code and passes the response back to the Web server, which, in turn, passes it back to the client’s Web browser.
What is the difference between uWSGI and WSGI?
uWSGI is a server and one of the protocols it implements is WSGI (do not confuse the uwsgi protocol with the uWSGI server). WSGI is a Python specification.
What does a WSGI do?
WSGI stands for “Web Server Gateway Interface”. It is used to forward requests from a web server (such as Apache or NGINX) to a backend Python web application or framework. From there, responses are then passed back to the webserver to reply to the requestor.

How does WSGI work Python?

How does Django ORM work?
Django lets us interact with its database models, i.e. add, delete, modify and query objects, using a database-abstraction API called ORM(Object Relational Mapper).
How does FastCGI work?
Basically, FastCGI is a program that manages multiple CGI requests within a single process, saving many program instructions for each request. Without FastCGI, each instance of a user requesting a service causes the Web server to open a new process that gets control, performs the service, and then is closed.
Why does Python need WSGI?
WSGI is a standard described on PEP 3333 and basically, provides a standard interface between web applications written in Python and Webservers. That means, WSGI gives portability to your Python Web Application across many different Web Servers, without any additional configurations on your NGINX, Apache, etc.
