您几乎可以使用**任何云服务商**来部署 FastAPI 应用程序。

在大多数情况下，主要的云服务商都有部署 FastAPI 的指南。

## 云服务商 - 赞助商

一些云服务商 ✨ [**赞助 FastAPI**](../help-fastapi.md#sponsor-the-author){.internal-link target=_blank} ✨，这确保了FastAPI 及其**生态系统**持续健康地**发展**。

这表明了他们对 FastAPI 及其**社区**（您）的真正承诺，因为他们不仅想为您提供**良好的服务**，而且还想确保您拥有一个**良好且健康的框架**：FastAPI。 🙇
