Gunicorn with Uvicorn Workers:

In Simple Words: Gunicorn acts as the master process manager, spawning and monitoring multiple worker processes (one per CPU core) running the Uvicorn ASGI event loop.

# Production deployment command:
gunicorn app.main:app   --workers 4   --worker-class uvicorn.workers.UvicornWorker   --bind 0.0.0.0:8000   --timeout 60
