uWSGI project aims at developing a full stack for building hosting services

If you want to make a hosted services eg an api that you would like to run all the time, uWSGI is quite a piece of software for this particular task. I even use uWSGI for my python rest api services.

Using uWSGI allows you to squeeze tremendously perfomes from your server by specifying frame, port, CPU usage, and a lot of other settings.
