Azure Stack HCI is a new hyperconverged infrastructure offering from Microsoft as an Azure service that enables hyperconverged infrastructure from Microsoft Azure to run virtual machines.

It provides all Microsoft’s new features and capabilities in terms of an enterprise hypervisor, blending on-premises capabilities with those found in Microsoft Azure.

The Azure Stack hyperconverged infrastructure solution runs on top of a custom-built operating system, separate from Windows Server 2019 or Windows Server 2022.

You can run Azure Stack HCI on your own datacenter hardware, or use ready-nodes from a certified Azure Stack HCI vendor, which is arguably the easier approach to ensure the hardware is supported.

Azure Stack HCI is equally adept running in large cluster configurations in the enterprise data center or in a simple two-node configuration in branch offices.

What Is HCI?

Hyperconverged infrastructure, or HCI for short, is a way of running virtual machines that's both efficient and easy to manage. It combines all the necessary components, such as software, hardware, and networking, into one cohesive unit.

In an HCI cluster, each server contains its own compute, storage, and networking functionality, and shares these resources with other cluster members without needing external devices.

This approach eliminates the need for separate storage area networks, or SANs, which can be a hassle to manage.
