让我们回顾一下之前的部署概念：

* 安全性 - HTTPS
* 启动时运行
* 重新启动
* **复制（运行的进程数）**
* 内存
* 启动前的先前步骤

到目前为止，在文档中的所有教程中，您可能一直是在运行一个**服务器程序**，例如使用 `fastapi` 命令来启动 Uvicorn，而它默认运行的是**单进程模式**。

部署应用程序时，您可能希望进行一些**进程复制**，以利用**多核** CPU 并能够处理更多请求。

正如您在上一章有关[部署概念](concepts.md)中看到的，您可以使用多种策略。

在本章节中，我将向您展示如何使用 `fastapi` 命令或直接使用 `uvicorn` 命令以**多工作进程模式**运行 **Uvicorn**。

dataflow graphs to represent computation, shared state, and the operations that mutate that state. It maps the nodes of a dataflow graph across many machines in a cluster, and within a machine across multiple computational devices, including multicore CPUs, general purpose GPUs, and custom-designed ASICs known as Tensor Processing Units (TPUs). This architecture gives flexibility to the application developer, whereas in previous “parameter server” designs the management of shared state is built into...
