Deploying with Gunicorn involves using this powerful WSGI HTTP server to run Python web applications in a production environment. Gunicorn, short for “Green Unicorn,” is designed to serve applications built with popular frameworks like Flask and Django. It operates on a pre-fork worker model, allowing multiple worker processes to handle incoming requests efficiently. This setup enhances performance and scalability, making it suitable for handling high traffic. By integrating Gunicorn with a reverse proxy server like Nginx, developers can ensure better load balancing and security for their applications, ultimately leading to a more robust deployment strategy.
