Billing model overview - Modular Data Center (MDC)
As a user of the MDC or Azure Stack Hub ruggedized, you are billed by Microsoft based on how long you have each appliance. The charge is per period, and includes the right to use the basic compute, storage and networking services. You are charged based on usage for App Service, Event Hubs, and any other PaaS services, as well as Windows Server PAYG VMs that run on Azure Stack Hub Ruggedized and MDC. If you are completely disconnected and cannot report usage data, you must obtain capacity licenses for PaaS services and bring your own licenses for Windows VMs.
Billing starts 14 days after an order for an appliance is shipped. For Azure Stack Hub Containerized, the initial billing period is one year. After one year, the order can be extended for an additional year, and another year of usage will be billed. If the order is not extended and the device is not returned, billing will continue on a monthly basis. For Azure Stack Hub ruggedized, billing is always on a monthly basis.
When the appliance is returned to Microsoft, billing stops as soon as the appliance is received back at the Microsoft warehouse.
