# RAS Provider Agent installation options

If you are installing a dedicated RAS Provider Agent, you first need to determine where it will be installed. Depending on the Provider type, the following options are available:

* The host on which the hypervisor is running. This option is available for Microsoft Hyper-V only.
* A supported version of Windows Server running on a physical box or in a virtual machine. For supported Windows Server versions, see **Software requirements** > **RAS Provider Agent**.

The following table lists RAS Provider Agent installation options for each supported Provider:

<table><thead><tr><th width="194">Provider</th><th>Built-in Agent (part of PA)</th><th>Agent on a Provider</th><th>Agent on a Windows Server (VM or HW)</th></tr></thead><tbody><tr><td>Microsoft Hyper-V</td><td>Yes</td><td>Yes</td><td>Yes*</td></tr><tr><td>Microsoft Hyper-V Failover Cluster</td><td>Yes</td><td>No</td><td>Yes*</td></tr><tr><td>VMware VCenter</td><td>Yes</td><td>No</td><td>Yes*</td></tr><tr><td>VMware ESXi</td><td>Yes</td><td>No</td><td>Yes*</td></tr><tr><td>SC//HyperCore</td><td>Yes</td><td>No</td><td>Yes*</td></tr><tr><td>Nutanix AHV (AOS)</td><td>Yes</td><td>No</td><td>Yes*</td></tr><tr><td>Remote PC (see the Note below)</td><td>Yes</td><td>No</td><td>Yes*</td></tr><tr><td>Microsoft Azure</td><td>Yes</td><td>No</td><td>Yes*</td></tr><tr><td>Amazon Web Services</td><td>Yes</td><td>No</td><td>Yes*</td></tr></tbody></table>

**\*** High Availability is not available with these Provider Agent installation options. For details, see [**Enabling high availability for VDI**](/landing/ras-admin-guide/parallels-ras-21-administrators-guide/virtual-desktop-infrastructure-vdi/enabling-high-availability-for-vdi.md).

{% hint style="info" %}
**Note:** The **Remote PC** is a special type that can be used to create and manage pools of Remote PCs as part of hosted desktop infrastructure (HDI). When you add a Provider of this type, you can manage it like one of the real Providers with some limitations, such as you cannot create templates and use some other strictly VDI-specific functions. The main feature when using this type is the ability to create pools of HDI-based Remote PCs (e.g. HPE Moonshot System, Atrust Remote PC Array) and making PCs persistent by assigning an individual PC to a specific user. For more info, see [**Remote PC pools**](/landing/ras-admin-guide/parallels-ras-21-administrators-guide/virtual-desktop-infrastructure-vdi/remote-pc-pools-in-vdi.md).
{% endhint %}

In the table above, find the Provider type that you are using and see where the RAS Provider Agent can be installed. Depending on the available choices, do one of the following:

* **Built-in Agent:** The agent is a part of RAS Connection Broker, so it is already installed. When possible, it is always recommended to use the built-in Provider Agent for high availability and business continuity.
* **Agent on a the provider:** This option is only available if you are using Microsoft Hyper-V. You can simply install the agent on the host, as described in [**Add a Provider**](/landing/ras-admin-guide/parallels-ras-21-administrators-guide/virtual-desktop-infrastructure-vdi/add-a-provider.md).
* **Agent on a Windows Server (VM or HW):** To use this option, make sure you have a physical box or a virtual machine running a supported version of Windows Server. You will need to specify its FQDN or IP address when adding a Provider to the Farm.
