Configure host scaling using the Azure portal

  • Article

This article helps you add more scale units (instances) to Azure Bastion to accommodate additional concurrent client connections. The steps in this article use the Azure portal. For more information about host scaling, see Configuration settings. You can also configure host scaling using PowerShell.

Configuration steps

  1. Sign in to the Azure portal.

  2. In the Azure portal, go to your Bastion host.

  3. Host scaling instance count requires Standard SKU tier or higher. On the Configuration page, for Tier, verify the tier is Standard or higher. If the SKU tier is Basic, select a higher SKU. To configure scaling, adjust the instance count. Each instance is a scale unit.

  4. Select Apply to apply changes.

    Note

    Any changes to the host scale units will disrupt active bastion connections.
