AKS Edge Essentials requirements and support matrix

The following are the requirements on the host machine that runs AKS Edge Essentials:

Hardware requirements

Specs Local cluster Arc-connected cluster and GitOps
Host OS Windows 10/11 IoT Enterprise/Enterprise/Pro and Windows Server 2019, 2022
Total physical memory 4 GB with at least 2.5 GB free 8 GB with at least 4.5 GB free
CPU 2 vCPUs, clock speed at least 1.8 GHz 4 vCPUs, clock speed at least 1.8 GHz
Disk space At least 14 GB free At least 14 GB free

To better understand the concept of vCPUs, read this article.

You can run AKS Edge Essentials on an Azure VM. You can create a Windows VM with either Windows 10/11 IoT Enterprise/Enterprise/Pro and Windows Server 2019, 2022 SKU, on a VM image that supports nested virtualization like the Dv5 and Dsv5-series virtual machines.


Running AKS Edge Essentials on a virtual machine, using nested virtualization is an experimental feature and is recommended only for developer use cases.

OS requirements

Install Windows 10/11 IoT Enterprise/Enterprise/Pro on your machine and activate Windows. We recommend using the latest client version 22H2 (OS build 19045) or Server 2022 (OS build 20348). You can download a version of Windows 10 here or Windows 11 here.

Maximum hardware specifications supported

Parameter Permissible limit
Maximum number of VMs per machine 1 Linux VM + 1 Windows VM (optional)
Maximum number of vCPUs assigned to virtual machines 16 vCPUs
Maximum number of machines per cluster 15 machines

GA Feature support matrix
