Une application SaaS éducative nécessite une séparation stricte des données entre établissements scolaires. L'architecture multi-tenant par sous-domaine (ecole-alpha.classeo.local) permet cette isolation tout en utilisant une base de code unique. Le choix d'une résolution basée sur les sous-domaines plutôt que sur des headers ou tokens facilite le routage au niveau infrastructure (reverse proxy) et offre une UX plus naturelle où chaque école accède à "son" URL dédiée.
