To Gunicorn or to Poetry, That is The Question | HackerNoon
Briefly

Gunicorn is ideal for production environments needing concurrency and high performance. The command to start it involves exporting environment variables and binding the server to a specific IP and port. The export command filters environment variable files to ensure only valid variables are used. In contrast, Poetry offers a simpler setup for development or debugging, running the application in a single thread without concurrency. The choice between Gunicorn and Poetry depends on application demands; Gunicorn is preferred for high-demand situations, while Poetry is for simpler needs.
Using Gunicorn is recommended for production environments requiring concurrency and high performance. Specify the number of workers, server IP, and port when starting.
The export command sets environment variables for the current shell. Grep filters out comments, and xargs formats the variables for export in one line.
Poetry is suitable for development or debugging scenarios without the need for concurrent execution. It runs Flask in a simpler, single-threaded mode.
Choosing between Gunicorn and Poetry depends on the performance requirements. Gunicorn excels in high-demand situations, while Poetry is sufficient for simpler setups.
