Azure Local

Microsoft's on-premises platform for Azure services in your own datacentre — 1 to 16 nodes, centrally managed through Azure Arc.

Overview

Azure Local in practice

Azure Local is the new name for Azure Stack HCI — Microsoft renamed the product with the 2411 release in November 2024, while the technology stayed the same. It brings the Azure operating model into your own datacentre: virtual machines, AKS clusters and Azure Virtual Desktop run on validated hardware on site, managed from the Azure portal through Azure Arc.

A hyperconverged instance spans 1 to 16 nodes and uses Storage Spaces Direct as its storage layer; disaggregated variants with external SAN storage scale to as many as 64 nodes. Billing is per physical processor core, and every system must connect to Azure at least once every 30 days. For strictly regulated environments there are disconnected operations with a local control plane; in production Microsoft requires a dedicated three-node management cluster for it.

Alendris deliberately designs hyperconverged clusters on Storage Spaces Direct and NVMe storage to be Azure Local compatible: connecting them to Azure later becomes a step, not a rebuild.
