Azure Local

What is Azure Local?

Azure Local is essentially the new name for Azure Stack HCI. Azure Local targets organizations who continue to have the need to run workloads upon on-premises infrastructure for compliance, security or other needs. Azure Local is often evaluated by organizations pursuing hybrid cloud strategies.

Azure Local is hyperconverged infrastructure software that runs directly on bare metal hardware validated by OEM partners. With it, you can run containers, virtual machines (both Linux and Windows VMs), and some Azure services at distributed locations with central management from the cloud, enabled by Azure Arc. Microsoft provides and supports the complete software stack, so you don’t need separate tools or vendors for the underlying virtualization or storage.

Azure Local is a hybrid product that connects the on-premises system to Azure for cloud-based services, monitoring, and management.

Azure Local can only be run upon hardware validated by Microsoft OEM partners, this means that it usually requires a dedicated hardware purchase to deploy. Many OEMs will provide their compatible hardware with Azure Local pre-installed.


What Happened to Azure Stack HCI?

Azure Stack HCI is now part of Azure Local. The same features and functionality continue to be offered in Azure Local. Azure Local provides additional flexibility: it supports smaller and larger deployments, more hardware, disconnected operations, and other capabilities such as new supported Azure services. Azure Local is essentially support for Azure Stack HCI in a wider range of configurations and scenarios.

Architecturally little has changed and a large amount of the Microsoft documentation continues to describe and explain the product using the “Azure Stack HCI” nomenclature / naming.


What is Azure Arc?

Azure Arc is a bridge that extends Azure to other environments and other clouds. Azure Local is an infrastructure solution that includes the capabilities of Azure Arc built-in and sets up automatically. Use Azure Local when you need new or refreshed infrastructure at distributed locations. Use Azure Arc when your environment already has infrastructure.


Does Microsoft Manage Azure Local?

No, customers own the hardware and have full responsibility for its day-to-day operations.

Some Azure Local customers choose to outsource some or all of the operational management to professional services providers or similar.


What Hardware is Validated for Azure Local?

The hardware compatibility lists for Azure Local are available in a catalogue maintained by Microsoft. See: Azure Local Solutions | Catalog.


Understanding Azure Stack HCI

Azure Stack HCI can combine the following:

  • Validated hardware from a hardware partner.
  • Azure Stack HCI operating system.
  • Hyper-V based compute resources.
  • Storage Spaces Direct-based virtualized storage.
  • Windows and Linux virtual machines as Arc-enabled servers.
  • Azure Virtual Desktop.
  • Azure services including monitoring, backup, site recovery, and more.
  • Azure portal, Azure Resource Manager and Bicep templates, Azure CLI and tools.

Use Cases for Azure Local

Remembering that Azure Local is built upon Azure Stack HCI, common use cases for Azure Local are:

  • Azure Virtual Desktop (AVD): Allows you to deploy AVD session hosts on-premises on Azure Local. Those session hosts are then managed from the Azure portal. See Azure Virtual Desktop on Azure Local | Azure Docs
  • Run Azure Arc services on-prem: Azure Arc allows you to run Azure services on-prem upon Azure Local systems to support hybrid workloads. Azure data and application services commonly run in this way include, Azure App Service, Functions, Logic Apps, Event Grid and API Management. Learn more: Azure Arc overview - Azure Arc | Azure Docs.
  • Highly performant SQL Server: Azure Stack HCI has purpose built support and optimizations for SQL Server as well as integrations with Azure Site Recovery. See: Deploy SQL Server on Azure Stack HCI (AKS-HCI) | Azure Docs for details.
  • Enterprise Virtualization: Azure Local is built upon the Microsoft Hyper-V hypervisor allowing the benefits of virtualization on-premises, this means it is often evaluated as an alternative to VMware ESXi for on-prem use cases. See: Deploy trusted enterprise virtualization on Azure Stack HCI | Azure Docs.
  • Scale-out Storage: Azure Stack HCI is a hyperconverged solution and provisions storage in a manner designed for scale-out use cases. This makes it suitable for those looking at an alternative to traditional / legacy storage provision mechanisms such as SAN or NAS. Learn more about Storage Spaces Direct as used by Azure Local, see: Storage Spaces Direct overview | Microsoft Learn.

Who Needs Azure Local

Azure Local offers an on-prem technology that suits certain needs particularly well, such as:

Organizations already invested in Microsoft technologies

If your environment is Microsoft-centric, Azure Local benefits include:

  • You’ll use core Microsoft technologies including Windows Server, Hyper-V, Active Directory, System Center, or Azure services. Technologies your existing staff skill set is likely to handle.
  • Azure Local facilitates a hybrid cloud that extends Azure to your data center.
  • Familiar Azure billing, Microsoft licensing, and Windows Admin Center for management.

Typical examples:

  • Enterprises with strong Windows/AD foundations.
  • Mid-sized businesses running mostly Microsoft workloads.
  • Government or regulated industries already certified with Microsoft infrastructure.

Hybrid Cloud and Edge Deployments

If you need to keep some workloads on-premises (for latency, data residency, or regulatory reasons) and already use or plan an Azure integration, Azure Stack HCI is ideal.

Example use cases:

  • Retail / manufacturing sites (branch/edge servers that sync with Azure).
  • Hospitals / banks / government needing local compute but Azure-based management and DR.
  • Disconnected or semi-connected environments that periodically sync to Azure.

Modernization of Legacy On-prem Virtualization Environments

Organizations using old Hyper-V clusters or VMware and SAN architectures may find the underling HCI stack of Azure Local an easier to scale alternative based around software defined infrastructure (compute + storage + networking). Features such as Storage Spaces Direct may appeal.

Azure Hybrid Cloud Strategy

If your IT strategy already includes Azure, Azure Local may be the natural choice, especially if you are:

  • Using Azure services for DR, monitoring, or compliance.
  • Wanting single-pane management across cloud + on-prem.
  • Already using Azure Arc to manage VMs, Kubernetes, and SQL servers anywhere.

In these scenarios Azure Local / Stack HCI gives you the “Azure experience” locally — same APIs, billing, and even unified policy enforcement.

VDI (Virtual Desktop Infrastructure) or Remote Workloads

Azure Local works particularly well for delivering AVD (Azure Virtual Desktop), closely integrated Microsoft technologies, it’s a good choice for those looking for a one-stop VDI solution for:

  • Running Azure Virtual Desktop (AVD) on-prem for performance/security reasons.
  • Providing low-latency virtual desktops in regulated or remote sites.

AVD is often evaluated as an alternative to Citrix Virtual Apps & Desktop (CVAD) and Omnissa Horizon.


When Azure Local May Not be a Good Fit

  • You don’t already use Azure or plan to integrate with it. If you do not have a hybrid cloud strategy, a traditional on-prem virtualization solution may better suit your needs such as VMWare ESXi or Microsoft Hyper-V, or an alternative HCI choice such as Nutanix.
  • You are pursuing a pure multi-cloud or open-source hypervisor strategy. Azure local would tie you in to proprietary closed source Microsoft technologies.
  • You are looking to virtualize very large-scale or mixed-OS performance workloads. If you are looking for very large clusters or working predominantly with Linux workloads, other alternatives may offer more flexibility.
  • Your needs are simple and require a few virtualized servers. Azure Local may be overkill for use cases that maybe better suited to simpler, lower-cost alternatives.

Azure Local (Azure Stack HCI) vs. Nutanix

Azure Local is often evaluated alongside solutions from Nutanix. Nutanix also offer HCI (Hyper Converged Infrastructure). The following table covers some of the similarities and differences between the two solutions and may help you evaluate which may be the best fit for your organization.

Azure Local Nutanix
Hybrid Cloud Integration Very strong; built to integrate with Azure services (monitoring, backup, Site Recovery, Arc, etc.) Strong multi-cloud and hybrid support; can extend on-prem to Azure or other clouds via Nutanix Clusters etc.
Ecosystem Fit Good fit if already invested in Microsoft stack (Windows Server, Azure, Active Directory) More agnostic; supports mixed environments and flexibility in hypervisor choice
Management & Operations Uses Windows Admin Center, Azure management tools, and native Azure tooling Provides its own management plane (Prism), unified for compute, storage, networking
Hypervisor Options Windows/Hyper-V + HCI stack Offers AHV (its own hypervisor) or supports VMware ESXi, Hyper-V, etc.
Flexibility & Portability Good for workloads that stay local with cloud integration; less abstraction from Azure More flexibility, especially in moving workloads across clouds or data centers, because it’s more vendor-neutral
Performance & Scalability Strong performance for many workloads; Microsoft validates hardware and configurations Very mature performance, especially in environments with heavy I/O, because Nutanix optimizes storage, caching, data locality
Cost Model Subscription/licensing tied to Microsoft and Azure usage; you may get benefits if you already have Azure agreements More freedom of hardware/software choice; but licensing costs, support, and scale economics are key considerations
Vendor Lock-in Considerations Strong tie to Microsoft’s ecosystem; easier to leverage Azure but also more bound to it Less tied to a single cloud vendor; easier to shift across different hypervisors or clouds
