“I’m already invested, so do I need to buy additional licenses when I move to cloud?”

This is one of the most frequently asked questions when it comes to migrating workloads to the cloud. Having made an existing investment in licensing is a huge consideration, and one that often leads to a delay in making the transition to public cloud.

Leveraging the capability of operating system license mobility under Software Assurance (SA) in the form of Azure Hybrid Use Benefit (AHUB) affords organisations huge discounts on their workload running costs when moving from on-premise infrastructure to Azure.

Enabling Azure HUB on new workloads being deployed is as simple as selecting a button in the portal during workload creation.

But what workloads that have already been deployed?

Fortunately, Azure Hybrid Use Benefit (AHUB) for Windows Server can be enabled through Azure Command Line Interface (CLI) with a simple command and organisations can start saving on their Azure consumption bill immediately.

To demonstrate the process, let’s first create a basic new virtual machine without enabling AHUB:

Now that the virtual machine, TestVM, is created, we can check the license status of it.

The “licenseType : null” field indicates that no existing operating system license is applied to the virtual machine, and the cost is included in the running cost of the particular workload.

Enabling Azure Hybrid Use Benefit (AHUB) is done by updating the license type key to include the operating system license. This is done with the following line in Azure CLI:

az vm update –name TestVM –resource-group TestGroup –license-type Windows_Server

Once executed, the output should produce the following result, indicating that a license has now been assigned to the workload:

The following example shows a 48% saving in the running cost of the virtual machine by simply leveraging AHUB.

AHUB not enabled:

AHUB enabled:

Enabling Azure Hybrid Use Benefit on existing workloads is a quick and efficient way to optimise the running costs of workloads in Azure and can result in significant savings.
