Create an Arm-based virtual machine using Microsoft Cobalt 100

Create an Arm-based Azure virtual machine using Cobalt 100

You can create an Arm-based Cobalt 100 virtual machine using the Microsoft Azure console, the Azure CLI tool, or Infrastructure as Code (IaC). For this Learning Path, you use the Azure console to create a virtual machine with an Arm-based Cobalt 100 processor.

You’ll focus on the general-purpose virtual machine of the D series. For more details, see Dpsv6 size series in the Microsoft Azure documentation.

If you haven’t used Microsoft Azure before, see Create a Linux virtual machine in the Azure portal .

Create an Arm-based Azure virtual machine

To create an Azure virtual machine based on Cobalt 100, launch the Azure portal and navigate to Virtual Machines.

• Select Create, and click on Virtual Machine from the drop-down list.
• In the Basic tab, fill in the instance details such as Virtual machine name and Region.
• Choose the image for your virtual machine (for example, Ubuntu 24.04 LTS) and select Arm64 as the VM architecture.
• In the Size field, select See all sizes and select the D-Series v6 family of virtual machines. Select D4ps_v6 from the list.

Select the D-Series v6 family of virtual machines

• Select SSH public key as an authentication type. Azure automatically generates an SSH key pair for you and allows you to store it for future use.
• Fill in the administrator username for your virtual machine.
• Select Generate new key pair, and select RSA SSH Format as the SSH key type. RSA offers better security with keys longer than 3072 bits. Give a key pair name to your SSH key.
• In Inbound port rules, select HTTP (80) and SSH (22) as the inbound ports.
