Je vais vous en dire un peu plus ici sur ces **concepts**, ce qui devrait vous donner l'**intuition** nécessaire pour décider comment déployer votre API dans des environnements très différents, voire même dans des environnements **futurs** qui n'existent pas encore.

En tenant compte de ces concepts, vous serez en mesure **d'évaluer et de concevoir** la meilleure façon de déployer **vos propres API**.
