# Concepts de déploiement { #deployments-concepts }

Lorsque vous déployez une application **FastAPI**, ou en fait n'importe quel type de web API, il existe plusieurs concepts qui vous importent probablement, et en les utilisant vous pouvez trouver la manière la **plus appropriée** de **déployer votre application**.

Parmi les concepts importants, on trouve :

* Sécurité - HTTPS
* Exécuter au démarrage
* Redémarrages

### Détails techniques au sujet du « subject » JWT `sub` { #technical-details-about-the-jwt-subject-sub }

La spécification JWT indique qu'il existe une clé `sub`, contenant le sujet du jeton.

Son utilisation est facultative, mais c'est là que vous placeriez l'identifiant de l'utilisateur ; nous l'utilisons donc ici.
