gunicorn tracking and usage

Gunicorn, also known as Green Unicorn, is a Python Web Server Gateway Interface (WSGI) HTTP server. It is used to serve Python web applications behind a reverse proxy, enhancing performance, and allowing concurrent processing. It is commonly used with popular frameworks like Django and Flask, among others.

A reverse proxy is used in conjunction with Gunicorn to handle client connections, forward requests to Gunicorn, and receive responses to be sent back to clients. It provides additional features like load balancing, SSL termination, and protection against slow client connections, increasing the stability and robustness of the web application.

Gunicorn can be easily installed using pip, the Python package manager. Simply run the command `pip install gunicorn` to install Gunicorn on your system. However, it is recommended to use a virtual environment in order to manage dependencies properly, and you can use the command `pipenv install gunicorn` within the environment.

Gunicorn can be started by executing it from your application's directory with the appropriate application name and variable. The server can be stopped using standard terminal commands.

Gunicorn settings can be configured using either command-line arguments or a configuration file. This allows you to customize worker processes, bind address, and other server settings to optimize performance.
