How a reservation discount is applied to Azure SQL Edge
After you buy Azure SQL Edge reserved capacity, the reservation discount is automatically applied to SQL Edge deployed to edge devices that match the attributes and quantity of the reservation. A reservation applies to the future use of Azure SQL Edge deployments. You're charged for software, storage, and networking at the normal rates.
How reservation discount is applied
A reservation discount is use-it-or-lose-it. So, if you don't have matching resources for any month, then you lose a reservation quantity for that month. You can't carry forward unused reserved months.
When you shut down a resource, the reservation discount automatically applies to another matching resource in the specified scope. If no matching resources are found in the specified scope, then the reserved months are lost.
Stopped resources are billed and continue to use reservation hours. To use your available reservation months with other workloads, deallocate or delete resources or scale-in other resources.
Discount applied to deployed devices
The reserved capacity discount is applied to deployed devices monthly. The reservation that you buy is matched to the usage emitted by the deployed device. For devices that don't run the full month, the reservation is automatically applied to other deployed devices matching the reservation attributes. The discount can apply to deployed devices that are running concurrently.
If you don't have any devices deployed for the entire month that align with the reservation attributes, you don't get the full benefit of the reservation discount for that month.
If your number of devices deployed exceeds your reservation quantity, then you're charged the nondiscounted cost for the number beyond the reservation quantity.
