`BackgroundTasks` funktioniert auch mit dem <abbr title="Einbringen von Abhängigkeiten">Dependency Injection</abbr> System. Sie können einen Parameter vom Typ `BackgroundTasks` auf mehreren Ebenen deklarieren: in einer *Pfadoperation-Funktion*, in einer Abhängigkeit (Dependable), in einer Unterabhängigkeit usw.

**FastAPI** weiß, was jeweils zu tun ist und wie dasselbe Objekt wiederverwendet werden kann, sodass alle Hintergrundtasks zusammengeführt und anschließend im Hintergrund ausgeführt...

Olası kombinasyonlar ve stratejiler:

* `--workers` ile **Uvicorn**
    * Bir Uvicorn **process manager** **IP** ve **port** üzerinde dinler ve **birden fazla Uvicorn worker process** başlatır.
* **Kubernetes** ve diğer dağıtık **container sistemleri**
    * **Kubernetes** katmanında bir şey **IP** ve **port** üzerinde dinler. Replikasyon, her birinde **tek bir Uvicorn process** çalışan **birden fazla container** ile yapılır.

///

## Deployment Kavramları { #deployment-concepts }

Bu örnekler server programını (ör. Uvicorn) çalıştırır; **tek bir process** başlatır, tüm IP'lerde (`0.0.0.0`) ve önceden belirlenmiş bir port'ta (ör. `80`) dinler.

Temel fikir budur. Ancak muhtemelen şunlar gibi bazı ek konularla da ilgilenmek isteyeceksiniz:

* Güvenlik - HTTPS
* Açılışta çalıştırma
* Yeniden başlatmalar
* Replikasyon (çalışan process sayısı)

Wenn Sie irgendeine Art von Validierung durchführen müssen, die eine Kommunikation mit einer **externen Komponente** erfordert, wie z. B. einer Datenbank oder einer anderen API, sollten Sie stattdessen **FastAPI-Abhängigkeiten** verwenden. Sie werden diese später kennenlernen.
