An Azure service that is used to provision Windows and Linux virtual machines.
It sounds like you have purchased Azure Reserved VM Instances for multiple VMs but are not seeing the reservation being fully utilized. Is that correct?
There are several factors that affect whether a VM qualifies for a reservation. You can review them here. It is also helpful to review how the discount gets applied.
My recommendation would be to open a support request, so a member of our billing team can review the details of your subscription and check why your reservation is not being utilized.
