## Concepts de déploiement { #deployment-concepts }

Ici, vous avez vu comment utiliser plusieurs workers pour paralléliser l'exécution de l'application, tirer parti de plusieurs cœurs du CPU et être en mesure de servir davantage de requêtes.

Dans la liste des concepts de déploiement ci-dessus, l'utilisation de workers aide principalement à la partie réplication, et un peu aux redémarrages, mais vous devez toujours vous occuper des autres :
