This release adds a new way to install an XS4 Face Server in Microsoft Azure.

### Azure installation {{% label type="new" %}} {{% label type="beta" %}} {#azure-installation}

The server installation wizard has a new Azure installation type.
It deploys an XS4 Face Server into your own Azure subscription, using a confidential or trusted launch virtual machine.
You enter your Azure details in the wizard, and the XS4 Face Console generates the **Azure Deployment Command** to run.
Salto technical support must enable this option for the site.
For more information, see [Azure installation](/xs4face/user-guide/systems-admin/server-installation#azure-installation).
