Configure host scaling using the Azure portal

This article helps you add additional scale units (instances) to Azure Bastion to accommodate additional concurrent client connections using the Azure portal. For more information about host scaling, see Configuration settings.

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

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