Azure Dedicated Host

A dedicated physical server to host your Azure VMs for Windows and Linux.

Deploy your Azure VMs in a dedicated environment

Azure Dedicated Host provides physical servers that host one or more Azure virtual machines. Your server is dedicated to your organization and workloads—capacity isn't shared with other customers. This host-level isolation helps address compliance requirements. As you provision the host, you gain visibility into and control over the placement of your Azure VMs, and you determine the host's maintenance policies.

Schedule maintenance operations on your terms

Deploy WindowsLinux, and SQL Server virtual machines on Azure. Select the server and CPU type, number of cores, and additional features. The underlying hosts you provision are single-tenant and dedicated to your Azure VMs and workloads. You determine the timing of all platform-initiated maintenance operations, such as OS patching, or hardware or software restarts. Select Azure VM sizes and operating systems on the same host.

Address compliance requirements

Comply with corporate policies and industry-specific standards by taking advantage of the certifications Azure offers. Place your Azure VMs on a dedicated hosting server that runs only your organization's workloads to meet corporate compliance guidelines and standards. Get insights on the underlying cores to meet server-based software licensing requirements.

Reduce costs by using existing software licenses

Use your on-premises Windows Server and SQL Server licenses with Software Assurance benefits, or subscriptions with equivalent rights, when you migrate your workloads to Dedicated Host. Azure Hybrid Benefit licensing terms are available only on Azure. You'll also get free extended security updates for Windows Server and SQL Server 2008/2012 and 2008/2012 R2.

Apply your existing Windows Server Datacenter or SQL Server Enterprise edition licenses to the physical cores available to you on the host, utilize dual-use rights while migrating from on premises, and get unlimited virtualization rights.

  • Dedicated Host pricing

    Dedicated Host is charged at the host level regardless of the number of Azure VMs you run on the host. Software licenses are billed separately from compute resources at a VM level based on usage. Use Azure Hybrid Benefit for additional savings, if you’re eligible. Estimate the costs for your Dedicated Host with the pricing calculator.

Frequently asked questions about Dedicated Host

  • You can deploy Dsv3, Esv3, and Fsv2 Azure VM series and more. You can also deploy multiple VM sizes within a VM series on the same host. However, there are some exceptions, such as the NVasv4_Type1 Dedicated Host SKU. For more information, read the documentation.

  • Dedicated Host is available in most Azure regions. For detailed regional availability, select your region from the Dedicated Host pricing page.

  • No. It provides a virtualized environment that's architected to run Azure VMs, and it gives you control and visibility over the underlying physical server.

  • Dedicated Host currently supports Azure Standard HDDs, Standard SSDs, and Premium SSDs. Learn more about Azure Disk Storage.

  • Microsoft can't provide guidance or opine on whether you’re able to consider Dedicated Host a capital lease financial expense. You must consult your own legal or accounting department to make that determination. The service provides dedicated physical servers and lets you keep the same asset IDs for the underlying hardware. In the event of a hardware change, the asset ID for the host will be a new asset ID when the physical hardware is changed. The host ID for the host resource won’t change, even in the event of a change of physical hardware.

  • The outsourcing software licensing terms applicable to Windows Server and SQL Server licenses acquired before October 1, 2019, allow you to allocate your existing licenses to Dedicated Host. If you’re eligible for Azure Hybrid Benefit, save more on Dedicated Host deployments. If you purchased new licenses after October 1, 2019, you may allocate them to Azure only via Azure Hybrid Benefit. You’ll need Software Assurance or subscriptions with equivalent rights to apply those licenses to Dedicated Host. Read the licensing FAQ for details.

  • Azure Hybrid Benefit applies to Windows Server Standard/Datacenter licenses and SQL Server Standard/Enterprise Core licenses with Software Assurance or subscription licenses with equivalent rights.

  • Yes, you'll get three years of free extended security updates for Windows Server and SQL Server 2008/2012 and 2008/2012 R2 running in Dedicated Host after the end of support.

  • Yes, you do. Under Azure Hybrid Benefit program, when you apply your existing Windows Server Datacenter licenses or SQL Server Enterprise edition licenses with Software Assurance to all the physical cores available to you on any given Dedicated Host server, you are granted unlimited virtualization rights. For example, if you have 32 existing Windows Server Datacenter licenses with Software Assurance on premises, you can use the same 32 licenses to install on a Dedicated Host as many Azure VMs running Windows Server as you want, subject to the physical capacity of the underlying server. You should license only the available physical cores on each Dedicated Host that you plan to provision (for example, 32 cores for a Dsv3 Type 1 Dedicated Host).

  • The available physical cores are calculated by dividing the available vCPUs in the host (listed on the pricing page) by the vCPU:core value for each VM series (see the Azure compute unit documentation). Most Azure VMs available on Dedicated Host offer a vCPU:core ratio equal to 2. For example, an Esv3 series Type 1 Dedicated Host has 32 available physical cores and a vCPU:core ratio equal to 2 and can host up to 64 vCPUs.

  • With unlimited virtualization rights you can substantially reduce your Windows Server and SQL Server licensing costs. Instead of licensing each Azure VM based on the number of vCPUs each VM has or using Azure Hybrid Benefit on each VM that you deploy on Azure Dedicated Host, you can license the entire set of available physical cores on each dedicated host. For example, if you have 32 existing Windows Server Datacenter licenses purchased before October 1, 2019, and you need to deploy 32 Dsv3 VMs each with 2 vCPUs on Azure Dedicated Host Type 1, you'd need:

    • 256 Windows Server Datacenter licenses if you took advantage of Azure Hybrid Benefit while applying the benefits at the VM level.
    • 40 Windows Server Datacenter licenses if you applied the outsourcing rule and licensed the entire number of physical cores that Azure Dedicated Host Type 1 has.
    • Only 32 Windows Server Datacenter licenses if you use Azure Hybrid Benefit unlimited virtualization rights on the same host.

    Additionally, you can use concurrently on Azure Dedicated Host and your on-premises licensed servers the same licenses for up to 180 days.

  • For SQL Server, you'll need the Enterprise edition and active Software Assurance or subscription licenses to be eligible for unlimited virtualization. For Windows Server, you'll need the Datacenter edition, and, if you use licenses acquired after October 1, 2019, you’ll also need active Software Assurance or subscription licenses to be eligible for unlimited virtualization on Dedicated Host.

    Windows Server Datacenter licenses purchased before October 1, 2019, have unlimited virtualization rights based on license-only rights. Licenses acquired after that date have unlimited virtualization rights only by virtue of Azure Hybrid Benefit.

    When allocating SQL Server or Windows Server licenses to a Dedicated Host using Azure Hybrid Benefit, you only have to license the available physical cores on the host (for example, 32 cores for an Esv3 series Type 1 Azure Dedicated Host).

    When allocating Windows Server licenses purchased prior to October 1, 2019, to the host, without using Azure Hybrid Benefit, you must license all of the physical cores of the host (for example, 40 cores for an Esv3 series Type 1 Azure Dedicated Host).
