사실상 거의 **모든 클라우드 제공업체**를 사용하여 여러분의 FastAPI 애플리케이션을 배포할 수 있습니다.

대부분의 경우, 주요 클라우드 제공업체에서는 FastAPI를 배포할 수 있도록 가이드를 제공합니다.

## 클라우드 제공업체 - 후원자들

몇몇 클라우드 제공업체들은 [**FastAPI를 후원하며**](../help-fastapi.md#sponsor-the-author){.internal-link target=_blank} ✨, 이를 통해 FastAPI와 FastAPI **생태계**가 지속적이고 건전한 **발전**을 할 수 있습니다.

이는 FastAPI와 **커뮤니티** (여러분)에 대한 진정한 헌신을 보여줍니다. 그들은 여러분에게 **좋은 서비스**를 제공할 뿐 만이 아니라 여러분이 **훌륭하고 건강한 프레임워크인** FastAPI 를 사용하길 원하기 때문입니다. 🙇

`FastAPI` est une classe Python qui fournit toutes les fonctionnalités nécessaires au lancement de votre API.

/// note | "Détails techniques"

`FastAPI` est une classe héritant directement de `Starlette`.

Vous pouvez donc aussi utiliser toutes les fonctionnalités de <a href="https://www.starlette.io/" class="external-link" target="_blank">Starlette</a> depuis `FastAPI`.

///

### Étape 2 : créer une "instance" `FastAPI`

Você também pode usá-lo para gerar código automaticamente para clientes que se comunicam com sua API. Por exemplo, aplicativos front-end, móveis ou IoT.

## Recapitulando, passo a passo

### Passo 1: importe `FastAPI`
