## Supported operating systems for Systems Manager
<a name="prereqs-operating-systems"></a>

Amazon Systems Manager provides support for a defined set of operating system (OS) versions that are actively supported by the OS vendor and are listed as supported in the Amazon Systems Manager documentation. Amazon Systems Manager OS support is aligned with vendors' lifecycles, as defined in their software terms of service. Not all operating systems or OS versions supported by a vendor are supported by Amazon Systems Manager.

Amazon Systems Manager support for an OS version ends when the OS vendor declares that version end-of-life (EOL). Support does not extend to vendor paid Extended Long-Term Support (ELTS), or similar paid programs. While customers can continue to use and install OS versions that have gone past vendor EOL, Amazon Support will only provide assistance if an issue is reproducible on a supported OS version.

New Amazon Systems Manager product releases, including new major releases of SSM Agent, do not add support for OS versions that are scheduled to reach vendor EOL within six months of the release date.

The following sections list the OSs and OS versions supported by Systems Manager.

**Note**  
If you plan to manage and configure Amazon IoT Greengrass core devices by using Systems Manager, those devices must meet the requirements for Amazon IoT Greengrass. For more information, see [Setting up Amazon IoT Greengrass core devices](https://docs.amazonaws.cn/greengrass/v2/developerguide/setting-up.html) in the *Amazon IoT Greengrass Version 2 Developer Guide*.  
If you plan to manage and configure Amazon IoT and non-Amazon edge devices, those devices must meet the requirements listed here and be configured as on-premises managed nodes for Systems Manager. For more information, see [Managing edge devices with Systems Manager](systems-manager-setting-up-edge-devices.md).

**Important**  
We strongly recommend that you avoid using OS versions that have reached End-of-Life (EOL). OS vendors including Amazon typically don't provide security patches or other updates for versions that have reached EOL. Continuing to use an EOL system greatly increases the risk of not being able to apply upgrades, including security fixes, and other operational problems. Amazon does not test Systems Manager functionality on OS versions that have reached EOL.  
Patch Manager might not support all the OS versions listed in this topic. For a list of OS versions supported by Patch Manager, see [Patch Manager prerequisites](patch-manager-prerequisites.md).

### Windows Server
<a name="prereqs-os-windows-server"></a>

SSM Agent requires Windows PowerShell 3.0 or later to run certain Amazon Systems Manager documents (SSM documents) on Windows Server instances (for example, the legacy `AWS-ApplyPatchBaseline` document). Verify that your Windows Server instances are running Windows Management Framework 3.0 or later. This framework includes Windows PowerShell. For more information, see [Windows Management Framework 3.0](https://www.microsoft.com/en-us/download/details.aspx?id=34595&751be11f-ede8-5a0c-058c-2ee190a24fa6=True).

**¹** **Windows Server 2012 and 2012 R2 support**: Windows Server 2012 and 2012 R2 reached end of support on October 10, 2023. To use SSM Agent with these versions, we recommend using Extended Security Updates (ESUs) from Microsoft. For more information, see [Windows Server 2012 and 2012 R2 reaching end of support](https://learn.microsoft.com/en-us/lifecycle/announcements/windows-server-2012-r2-end-of-support) on the Microsoft website.

## Supported machine types in hybrid and multicloud environments
<a name="supported-machine-types"></a>

Systems Manager supports several machine types as *managed nodes*. A managed node is any machine configured to work with Systems Manager.

This user guide uses the term *hybrid and multicloud* to refer to an environment that contains any combination of the following machine types:
+ Amazon Elastic Compute Cloud (Amazon EC2) instances
+ Servers on your own premises (on-premises servers)
+ Amazon IoT Greengrass core devices
+ Amazon IoT and non-Amazon edge devices
+ Virtual machines (VMs), including VMs in other cloud environments

For information about Amazon support for hybrid and multicloud environments, see [Amazon Solutions for Hybrid and Multicloud](https://www.amazonaws.cn/hybrid-multicloud/).
