# À vous de créer :
|
|
# 1. Un VPC personnalisé avec auto_create_subnetworks = false
|
|
# 2. Trois sous-réseaux (frontend, backend, database)
|
|
# 3. Règles de firewall :
|
|
# - HTTP/HTTPS vers frontend
|
|
# - SSH vers toutes les instances
|
|
# - Port 8000 de frontend vers backend
|
|
# - Port 3306 de backend vers database
|
|
