Your reservation discount applies to virtual machines, SQL databases, Azure Cosmos DB, or other resources that match your reservation and run in the reservation scope. The billing context is dependent on the subscription used to buy the reservation.
You can scope a reservation to a management group. When you set the scope to a management group, the reservation discount is applied to matching resources in the list of subscriptions that are a part of the management group and the billing context.
