Hello,
Etant donné que l'autoscaling des webapp est une ressource à part entière, oui c'est envisageable de faire une policy en deployIfNotExits. Par contre attention, en terme de délai d'application de la policy il n'y a pas de SLA.

Voici le template ARM pour l'autoscaling : https://github.com/Azure/azure-quickstart-templates/blob/master/monitor-autoscale-webappserviceplan-simplemetricbased/azuredeploy.json

il est possible de lancer le autoshutdown à un jour particulier de la semaine ? par exemple arrêter les machines tous les vendredi à une certaine heure
