PBX Express and Azure Reserved Instance

[poynter.net]

Can PBX Express be used with Azure RI?

Looks like it, run PBXExpress, then apply the RI:

"After you buy an Azure Reserved Virtual Machine Instance, the reservation discount is automatically applied to virtual machines that match the attributes and quantity of the reservation. A reservation covers the compute costs of your virtual machines. "

Anyone had any experience of using this?
