Deploying with Gunicorn involves using this powerful Python WSGI HTTP server to serve web applications built with frameworks like Flask and Django. Gunicorn, which stands for “Green Unicorn,” operates on a pre-fork worker model, allowing it to handle multiple requests simultaneously by spawning multiple worker processes. This makes it an efficient choice for production environments, as it can effectively manage load and improve application performance. When combined with a reverse proxy server like Nginx, Gunicorn can enhance security and scalability, making it a popular choice for deploying Python web applications in real-world scenarios.
