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. 🙇

Um `EmailStr` zu verwenden, installieren Sie zuerst <a href="https://github.com/JoshData/python-email-validator" class="external-link" target="_blank">`email-validator`</a>.

Stellen Sie sicher, dass Sie eine [virtuelle Umgebung](../virtual-environments.md){.internal-link target=_blank} erstellen, sie aktivieren und es dann installieren, zum Beispiel:

```console
$ pip install email-validator

FastAPI CLI 接收你的 Python 程式路徑（例如 `main.py`），並自動檢測 FastAPI 實例（通常命名為 `app`），確定正確的引入模組流程，然後運行該應用程式。

在生產環境，你應該使用 `fastapi run` 命令。 🚀

**FastAPI CLI** 內部使用了 <a href="https://www.uvicorn.dev" class="external-link" target="_blank">Uvicorn</a>，這是一個高效能、適合生產環境的 ASGI 伺服器。 😎
