# Implantar FastAPI em provedores de nuvem

Você pode usar praticamente **qualquer provedor de nuvem** para implantar seu aplicativo FastAPI.

Na maioria dos casos, os principais provedores de nuvem têm guias para implantar o FastAPI com eles.

/// info

The <a href="https://github.com/Kludex/python-multipart" class="external-link" target="_blank">`python-multipart`</a> package is automatically installed with **FastAPI** when you run the `pip install "fastapi[standard]"` command.

However, if you use the `pip install fastapi` command, the `python-multipart` package is not included by default.
