Use Azure portal to create an Arm-based virtual machine

In this section, you’ll create a virtual machine with the Arm-based Azure Cobalt 100 processor using the Azure portal.

This Learning Path uses a memory-optimized virtual machine in the Epdsv6 series. For more information, see the Microsoft Azure guide for the Epdsv6 size series .

While the steps to create this instance are included here for convenience, you can also refer to the Deploy a Cobalt 100 virtual machine on Azure Learning Path .

Configure an Azure Cobalt 100 virtual machine

Creating a virtual machine on Azure Cobalt 100 follows the standard Azure VM flow. You specify basic settings, select an operating system image, configure authentication, and set up networking and security options.

For more information, see the Azure VM creation documentation .

To create a VM using the Azure portal, follow these steps:

  1. In the Azure portal, go to Virtual machines.

  2. Select Create, then choose Virtual machine from the drop-down.

  3. On the Basics tab, enter Virtual machine name and Region.

  4. Under Image, choose your OS (for example, Ubuntu Pro 24.04 LTS) and set Architecture to Arm64.

  5. In Size, select See all sizes, choose the E-series v6 series, then select E4pds_v6.

  6. Under Authentication type, choose SSH public key. Azure can generate a key pair and store it for future use. For SSH key type, ED25519 is recommended (RSA is also supported).

  7. Enter the Administrator username.

  8. If generating a new key, select Generate new key pair, choose ED25519 (or RSA), and provide a Key pair name.

  9. In Inbound port rules, select HTTP (80) and SSH (22).

  10. Select Review + create and review your configuration. It should look similar to:

  11. When you’re ready, select Create, then Download private key and create resources.

  12. After deployment completes, confirm that the VM is running and note the public IP address.

Your virtual machine should be ready in a few minutes. You can then connect over SSH using your private key and the VM public IP address.

What you’ve accomplished and what’s next

You’ve now created an Arm-based Azure Cobalt 100 virtual machine and confirmed the deployment details needed for SSH access.

Next, you’ll install Elasticsearch and ESRally on the virtual machine.
