:Microsoft licenses and Software Assurance

Last Updated:Aug 12, 2025

When you want to deploy your business in a Microsoft software-based environment, Microsoft licenses can be provided through Alibaba Cloud.

You can use one of the following methods to use a Microsoft license in Alibaba Cloud:

  • Use Microsoft licenses provided by Alibaba Cloud

    Purchase Microsoft licenses from Alibaba Cloud. These licenses are included in Windows Server public images that are provided by Alibaba Cloud or Alibaba Cloud Marketplace images that have SQL Server pre-installed.

  • Bring your own license

    If you have purchased a Microsoft license, apply for Microsoft License Mobility through Software Assurance to bring your own license (BYOL) to Alibaba Cloud.

Use Microsoft licenses provided by Alibaba Cloud

Alibaba Cloud provides Microsoft licenses through the Services Provider License Agreement (SPLA). Alibaba Cloud Elastic Compute Service (ECS) and ApsaraDB RDS provide software licensed by Microsoft, such as Windows Server images and ApsaraDB RDS for SQL Server. Client Access Licenses (CALs) are not required for Alibaba Cloud ECS instances that run Windows Server images. By default, each Windows Server instance has two connections that are used only for management purposes. If you need more connections or want to use the connections for non-management purposes. If you need more than two connections, or need to use the connections for non-management purposes, additional Remote Desktop Services CALs (RDS CALs) are required.

The following table lists the Windows Server and SQL Server versions that Alibaba Cloud provides. For more information, see Create an instance on the Custom Launch tab.

Note

Starting January 14, 2020, Microsoft no longer provides support for Windows Server 2008 and Windows Server 2008 R2. Alibaba Cloud no longer provides technical support for ECS instances that run the preceding operating systems. If your ECS instances run the preceding operating systems, we recommend that you upgrade to Windows Server 2016 or later at the earliest opportunity. For more information, see Windows Server EOL guidance.

Bring your own license

If you have existing Microsoft licenses, you can bring them to Alibaba Cloud under the Bring Your Own License (BYOL) model. Your options depend on whether your licenses include Software Assurance coverage. For more information about Software Assurance, visit the official Microsoft website.

Note

You can import a BYOL image to Alibaba Cloud and use this image to create ECS instances. Set License Type to BYOL when you import a BYOL image. For more information, see Import a custom image.

  • Microsoft licenses without Software Assurance coverage

    If your Microsoft licenses do not include Software Assurance, you must run them on services that provide dedicated physical hardware, such as ECS Bare Metal Instances or Dedicated Hosts. Because you are the sole tenant of the hardware, you can use your existing licenses on these services. For more information, see Overview and What is DDH?.

    Important

    To meet compliance requirements, you must have obtained your license before October 1, 2019 and the operating system versions must have been released before October 1, 2019.

    All Microsoft software covered by the Microsoft Product Terms can be deployed on ECS bare metal instances or dedicated hosts. Examples include:

    • Microsoft Windows Server

    • Microsoft Exchange Server

    • Microsoft SharePoint Server

    • Microsoft SQL Server

    • Microsoft System Center

    • Microsoft Dynamics

    • MSDN

    • Microsoft Remote Desktop Services (user CALs)

  • Microsoft licenses with Software Assurance coverage

    If your licenses have Software Assurance coverage, you can migrate them to Alibaba Cloud by using License Mobility. Before you migrate your services to ECS, you must verify your license eligibility through the License Mobility program. For more information, see Apply for License Mobility and What is SMC?.

    The following list describes eligible Microsoft applications and services:

    • Microsoft Exchange Server

    • Microsoft SharePoint Server

    • Microsoft SQL Server

    • Microsoft System Center

    • Microsoft Dynamics

    • Microsoft BizTalk Server

    • Microsoft Remote Desktop Services (user CALs)
