Microsoft makes SQL Server on Azure Local generally available

Microsoft has made SQL Server on Azure Local generally available for connected and disconnected operations on infrastructure in customers’ own environments.

The release gives organizations a choice between Azure-connected management and a local control plane for sites where external connectivity is restricted or unavailable. In both modes, SQL Server runs in Windows Server or Linux virtual machines on Azure Local, allowing database workloads and data to remain in a customer’s datacenter or edge location instead of moving to a public-cloud database service.

In connected deployments, Azure Local maintains a connection to Azure. Customers can connect SQL Server instances to Azure Arc for centralized inventory, governance, monitoring, security and licensing, while the databases continue to run locally. The setup focuses on locally placed workloads, unlike Microsoft’s separate Azure-to-AWS private networking preview, which addresses links between cloud environments.

Disconnected operations move the Azure Local control plane into the customer environment and remove an ongoing dependency on the Azure public-cloud control plane. Microsoft positions that mode for regulated, sovereign, remote and air-gapped settings, including sites with intermittent network access.

The two modes do not have identical management features. Microsoft’s SQL Server on Azure Local documentation says the SQL Server extension for Azure Arc is not supported in disconnected deployments. Its Azure-hosted SQL inventory, best-practices assessments and SQL management experiences are therefore unavailable; administrators use supported local tools instead.

Microsoft says the release lets customers retain control over infrastructure, connectivity and data placement. It also says keeping databases near users, devices, factories or application servers can reduce data movement and inference latency. Microsoft did not provide customer adoption figures or independent performance benchmarks with the release.

SQL Server licensing remains separate from Azure Local. Microsoft says connected deployments can use eligible existing SQL Server licenses or pay-as-you-go licensing through Azure Arc. Fully disconnected deployments can use eligible existing licenses through Azure Hybrid Benefit, subject to applicable licensing terms. The company did not publish a fixed price for the configuration.

Disconnected operations also carry infrastructure and access requirements. Microsoft’s documentation says customers need extra capacity for a local virtual appliance, a dedicated management cluster and supported Premier Solutions hardware. They must also have an eligible Microsoft agreement, qualifying support, a valid business need and staff or a partner able to run the environment.

Microsoft also presents Foundry Local on Azure Local as a way to run AI inference near SQL Server data. That product remains in preview and is not included in the SQL Server on Azure Local general-availability milestone.
