Provision Azure infrastructure for Redis

Create an Arm-based Cobalt 100 virtual machine to host your Redis deployment.

Prerequisites and setup

There are several common ways to create an Arm-based Cobalt 100 virtual machine, and you can choose the method that best fits your workflow or requirements:

  • The Azure Portal
  • The Azure CLI
  • An infrastructure as code (IaC) tool

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

The Learning Path focuses on general-purpose virtual machines in the Dpsv6 series. For more information, see the Microsoft Azure guide for the Dpsv6 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 .

Create an Arm-based Azure virtual machine

Creating a virtual machine based on Azure Cobalt 100 is no different from creating any other virtual machine in Azure. To create an Azure virtual machine:

  • Launch the Azure portal and navigate to Virtual Machines.
  • Select Create, and select Virtual Machine from the drop-down list.
  • Inside the Basic tab, fill in the instance details such as Virtual machine name and Region.
  • Select the image for your virtual machine (for example, Ubuntu Pro 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 as shown in the diagram below:

  • For Authentication type, select SSH public key.
Note

Azure generates an SSH key pair for you and lets you save it for future use. This method is fast, secure, and easy for connecting to your virtual machine.

  • Fill in the Administrator username for your VM.
  • Select Generate new key pair, and select RSA SSH Format as the SSH Key Type.
Note

RSA offers better security with keys longer than 3072 bits.

  • Give your SSH key a key pair name.
  • In the Inbound port rules, select HTTP (80) and SSH (22) as the inbound ports, as shown below:

  • Now select the Review + Create tab and review the configuration for your virtual machine. It should look like the following:

  • When you’re happy with your selection, select the Create button and then Download Private key and Create Resource button.

Your virtual machine should be ready and running in a few minutes. You can SSH into the virtual machine using the private key, along with the public IP details.

What you’ve learned and what’s next

You’ve created an Azure Cobalt 100 Arm64 virtual machine running Ubuntu 24.04 LTS with SSH authentication configured. The virtual machine is now ready for installing and running Redis workloads.

Next, you’ll install Redis on the VM and begin building a real-time messaging and event processing system using Pub/Sub and Redis Streams.
