General availability: Virtual Machine software reservations

The new Virtual Machine software reservations enable savings on your Virtual Machine software costs when you make a one- to three-year commitment for plans offered by third-party publishers such as Canonical, Citrix, and Red Hat.

You can choose to pay monthly or up-front
You can change the size of the deployed Virtual Machine, and Microsoft handles the application of reservation benefits and overage charges
You do not have to redeploy your workloads to use the reservation benefits
