Ce qui fait qu'avec une URL comme :

```
http://localhost:8000/items/?q=foo&q=bar
```

vous recevriez les valeurs des multiples paramètres de requête `q` (`foo` et `bar`) dans une `list` Python au sein de votre fonction de **path operation**, dans le paramètre de fonction `q`.

전단계에서의 배포 개념들을 다시 확인해보겠습니다:

* 보안 - HTTPS
* 서버 시작과 동시에 실행하기
* 재시작
* **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.
