Server code upgrade

We are aiming to provide a more robust server with standard practices. Please research what would be ideal for our data collection process with different scales. The focus is to ensure a reliable connection for handling frequent incoming data transaction requests under HTTPS.

The solution I recommend would be Nginx + Gunicorn + Fastapi + Redis.
Other potential tools include Apache, Flask, Django, and more.
