它不是 Web 框架，而是服务器。例如它不提供按路径路由的工具——这是 Starlette（或 **FastAPI**）这类框架在其之上提供的功能。

它是 Starlette 与 **FastAPI** 推荐的服务器。

/// check | **FastAPI** 推荐将其作为：

运行 **FastAPI** 应用的主要 Web 服务器。

你也可以使用 `--workers` 命令行选项以获得异步的多进程服务器。

FastAPI アプリケーションでは、Uvicorn を実行する `fastapi` コマンドのようなサーバープログラムを使用し、**1つのプロセス**で1度に複数のクライアントに同時に対応できます。

しかし、多くの場合、複数のワーカー・プロセスを同時に実行したいと考えるでしょう。

### 複数のプロセス - Worker { #multiple-processes-workers }

クライアントの数が単一のプロセスで処理できる数を超えており（たとえば仮想マシンがそれほど大きくない場合）、かつサーバーの CPU に**複数のコア**がある場合、同じアプリケーションで同時に**複数のプロセス**を実行させ、すべてのリクエストを分散させることができます。

同じAPIプログラムの**複数のプロセス**を実行する場合、それらは一般的に**Worker／ワーカー**と呼ばれます。
