## Conceitos de Implantação { #deployment-concepts }

Aqui você viu como usar vários **trabalhadores** para **paralelizar** a execução do aplicativo, aproveitar **vários núcleos** na CPU e conseguir atender **mais solicitações**.

O atributo `model_config` é usado apenas para configuração do Pydantic. Você pode ler mais em <a href="https://docs.pydantic.dev/latest/concepts/config/" class="external-link" target="_blank">Pydantic: Concepts: Configuration</a>.

При деплое приложения вам, скорее всего, захочется использовать **репликацию процессов**, чтобы задействовать **несколько ядер** и иметь возможность обрабатывать больше запросов.

Как вы видели в предыдущей главе о [Концепциях деплоя](concepts.md){.internal-link target=_blank}, существует несколько стратегий.

Здесь я покажу, как использовать **Uvicorn** с **воркер-процессами** через команду `fastapi` или напрямую через команду `uvicorn`.

    * In requests and responses will be represented as a `float` of total seconds.
    * Pydantic also allows representing it as a "ISO 8601 time diff encoding", <a href="https://docs.pydantic.dev/latest/concepts/serialization/#custom-serializers" class="external-link" target="_blank">see the docs for more info</a>.

    * In requests and responses, treated the same as a `set`:

    * En requests y responses se representará como un `float` de segundos totales.

FastAPI는 이를 위해 Pydantic 모델의 `.dict()`의 <a href="https://docs.pydantic.dev/latest/concepts/serialization/#modeldict" class="external-link" target="_blank"> `exclude_unset` 매개변수</a>를 사용합니다.

* `response_model_exclude_none=True`

    * Wird in Requests und Responses als `float` der Gesamtsekunden dargestellt.
    * Pydantic ermöglicht auch die Darstellung als „ISO 8601 Zeitdifferenz-Kodierung“, <a href="https://docs.pydantic.dev/latest/concepts/serialization/#custom-serializers" class="external-link" target="_blank">siehe die Dokumentation für weitere Informationen</a>.
* `frozenset`:
    * Wird in Requests und Responses wie ein `set` behandelt:
