# Despliega FastAPI en Proveedores de Nube { #deploy-fastapi-on-cloud-providers }

Puedes usar prácticamente **cualquier proveedor de nube** para desplegar tu aplicación FastAPI.

En la mayoría de los casos, los principales proveedores de nube tienen guías para desplegar FastAPI con ellos.

<a href="https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS" class="external-link" target="_blank">CORS ou "Cross-Origin Resource Sharing"</a> refere-se às situações em que um frontend rodando em um navegador possui um código JavaScript que se comunica com um backend, e o backend está em uma "origem" diferente do frontend.

/// tip

Alternatively, you can perform the same steps that scripts does manually.

Go into the language directory, for the main docs in English it's at `docs/en/`:

```console
$ cd docs/en/
```

Then run `mkdocs` in that directory:

```console
$ mkdocs serve --dev-addr 127.0.0.1:8008
```

<a href="https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS" class="external-link" target="_blank">CORS or "Cross-Origin Resource Sharing"</a> refers to the situations when a frontend running in a browser has JavaScript code that communicates with a backend, and the backend is in a different "origin" than the frontend.

...et déclarez que son type est le modèle que vous avez créé : `Item`.

## Résultats

En utilisant uniquement les déclarations de type Python, **FastAPI** réussit à :

* Lire le contenu de la requête en tant que JSON.
* Convertir les types correspondants (si nécessaire).
* Valider la donnée.
