Deployment

Development and production have different running methods. Production environments use WSGI/ASGI servers and reverse proxies.

Technology Choices:

• WSGI: Gunicorn + gevent/Meinheld, or Waitress (Windows)
• ASGI: Uvicorn + asgiref (Flask 3 provides experimental async view support)
• Frontend with Nginx/Apache for reverse proxy, TLS, static resources

Gunicorn Example:

pip install gunicorn gevent
export FLASK_APP=app:create_app
gunicorn -w 4 -k gevent -b 0.0.0.0:8000 "app:create_app()"

Containerization:

FROM python:3.11-slim
WORKDIR /app
COPY . .
RUN pip install -r requirements.txt
CMD ["gunicorn", "-w", "4", "-b", "0.0.0.0:8000", "app:create_app()"]

Configuration:

• Inject sensitive information through environment variables
• Enable health checks and readiness probes
• Use process management/daemons (systemd/supervisor)
