Structure des modules Terraform¶

Les fichiers Terraform sont répartis en deux niveaux :

terraform/           ← point d'entrée (terraform init/apply lancé ici)
  1_main.tf          ← orchestration des modules
  2_variables.tf     ← déclaration des variables
  3_providers.tf     ← provider azurerm v4.54.0
  terraform.tfvars   ← valeurs des variables (subscription, credentials)

modules/             ← modules réutilisables (racine du projet)
  event_hubs/        ← namespace Event Hubs + 3 hubs + policies send/listen
  sql_database/      ← SQL Server + base dwh-shopnow (S0) + container db-setup
  stream_analytics/  ← job ASA + inputs Event Hubs + outputs SQL + démarrage
  container_producers/ ← ACI producteurs Python (orders/products/clickstream)
