When you use Azure Bastion, VMs don't require a client, agent, or additional software. For more information about Azure Bastion, see the [Overview](bastion-overview.md). For more information about virtual machine scale sets, see [What are virtual machine scale sets?](/azure/virtual-machine-scale-sets/overview) ## Prerequisites Make sure that you have set up an Azure Bastion host for the virtual network in which the virtual machine scale set resides. For more information, see [Create an Azure Bastion host](tutorial-create-host-portal.md). Once the Bastion service is provisioned and deployed in your virtual network, you can use it to connect to a virtual machine scale set instance in this virtual network. ## <a name="rdp"></a>Connect This section helps you connect to your virtual machine scale set. 1. Open the [Azure portal](https://portal.azure.com) and go to **Virtual machine scale sets**. To open the scale sets instances page, click the scale set that contains the instance that you want to connect to. 1. On the **Scale set instance** page, click the instance that you want to connect to. This opens the page for the instance. 1. On the instance page, select **Connect** at the top of the page, then choose **Bastion** from the dropdown. 1. On the **Bastion** page, fill in the required settings. The settings you can select depend on the virtual machine to which you're connecting, and the [Bastion SKU](bastion-sku-comparison.md) tier that you're using. For more information about settings, see [Bastion configuration settings](configuration-settings.md). 1. After filling in the values on the Bastion page, select **Connect** to connect to the instance. ## Next steps Read the [Bastion FAQ](bastion-faq.md).
