Why production setup matters in Flask - Quick Recap

Recall & Review

beginner

What is the main reason to have a production setup for a Flask app?

A production setup ensures the app runs securely, efficiently, and reliably for real users, unlike the simple development server meant only for testing.

beginner

Why should you not use Flask's built-in server in production?

Flask's built-in server is single-threaded and not designed for handling many users or security threats, so it can crash or expose vulnerabilities in production.

What role does a WSGI server like Gunicorn or uWSGI play in production?

They act as a bridge between the web server and Flask app, managing multiple requests efficiently and improving performance and stability.

intermediate

How does configuring environment variables help in production?

It keeps sensitive data like passwords and API keys out of the code, making the app safer and easier to manage across different environments.

beginner

What is the benefit of using HTTPS in a production Flask app?

HTTPS encrypts data between users and the server, protecting sensitive information from being intercepted or tampered with.

Why is Flask's built-in server not suitable for production?

A It uses HTTPS by default

B It supports too many users

C It automatically scales the app

D It is single-threaded and not secure

Flask's built-in server is simple and single-threaded, making it unsuitable for handling multiple users or security needs in production.

What does a WSGI server do in a Flask production setup?

A Replaces the Flask app code

B Runs the Flask app and manages multiple requests

C Creates the database

D Handles frontend styling

A WSGI server like Gunicorn runs the Flask app and efficiently manages multiple user requests.

Which of these is a good practice for production security?

A Using environment variables for secrets

B Hardcoding passwords in code

C Disabling HTTPS

D Running Flask debug mode

Using environment variables keeps secrets out of code and improves security.

What is the benefit of HTTPS in production?

A Encrypts data between user and server

B Allows unlimited users

C Faster page loading

D Disables cookies

HTTPS encrypts data to protect user information from interception.

Which tool is commonly used to serve Flask apps in production?

A SQLite

B Flask built-in server

C Gunicorn

D Bootstrap

Gunicorn is a popular WSGI server used to serve Flask apps in production.
