#### Gateway

Gateway (referring to the [Kubernetes API](http://gateway-api.org/), not the same-named Istio type) works very similarly to [Ingress](#ingress). The Gateway controller also converts Gateway API types into `VirtualService` and `Gateway`, implementing the `ConfigStore` interface.

⏮️ **FastAPI** 👆 📣 🔢 ⏮️ 🆎 🔑 &amp; 👆 🤚:

* **복제본 (실행 중인 프로세스의 숫자)**
* 메모리
* 시작하기 전의 여러 단계들

지금까지 문서의 모든 튜토리얼을 참고하여 **단일 프로세스**로 Uvicorn과 같은 **서버 프로그램**을 실행했을 것입니다.

애플리케이션을 배포할 때 **다중 코어**를 활용하고 더 많은 요청을 처리할 수 있도록 **프로세스 복제본**이 필요합니다.

전 과정이었던 [배포 개념들](concepts.md){.internal-link target=_blank}에서 본 것처럼 여러가지 방법이 존재합니다.

지금부터 <a href="https://gunicorn.org/" class="external-link" target="_blank">**구니콘**</a>을 **유비콘 워커 프로세스**와 함께 사용하는 방법을 알려드리겠습니다.

Pydantic 是 FastAPI 中所有数据验证和序列化的核心，当你在没有设默认值的情况下使用 `Optional` 或 `Union[Something, None]` 时，它具有特殊行为，你可以在 Pydantic 文档中阅读有关<a href="https://docs.pydantic.dev/latest/concepts/models/#required-optional-fields" class="external-link" target="_blank">必需可选字段</a>的更多信息。

### 使用Pydantic中的`Required`代替省略号(`...`)

如果你觉得使用 `...` 不舒服，你也可以从 Pydantic 导入并使用 `Required`：
