Dear Alibaba Cloud users,

From November 29, 2021, Alibaba Cloud starts to roll out updates based on Bastionhost V3.2.22. The features of Bastionhost V3.2.22 include new features and the features that are optimized based on V3.2.20 and V3.2.21.

New features

Bastionhost V3.2.22 introduces the following new features:
  • Authorization rules can be created. You can create authorization rules to authorize multiple users to manage hosts. You can also specify a validity period for an authorization rule.
  • The import and export of bastion host configurations are supported. You can export the configurations of a bastion host and import the exported configurations for use on other bastion hosts.
  • The proxy mode of the network domain feature is supported by Bastionhost HA Edition. This allows you to configure a secondary proxy server in a network domain. If an error occurs on the primary proxy server, the secondary proxy server is automatically connected to your bastion host.
For more information about the supported features, see Release notes.

Update methods

You can update your bastion host in custom or automatic mode.
  • Custom: You can specify a custom period during which you want to update your bastion host. The period must be within the available update period for the region of your bastion host For more information, see Update a bastion host.
    Notice If you choose the automatic mode, your bastion host is updated during a default period. Bastionhost randomly determines default periods based on available update periods.

    If you want to update your bastion host during a custom period, we recommend that you specify the custom period at the beginning of the available update period for the region of your bastion host. If you do not specify the custom period at the beginning of the available update period, your bastion host may be automatically updated when a default period starts.

  • Automatic: Your bastion host is automatically updated when a default period starts. If you do not specify a custom period for an update, your bastion host is automatically updated during a default period.
    Notice The default period may overlap with the peak hours of your business. This may affect your business. To prevent business interruptions, we recommend that you specify a custom period during which the impact of an update is minimized.

Impact

If your bastion host is being updated, it is in the Updating Configuration state, and your business may be interrupted for a few seconds. We recommend that you specify a custom period to update your bastion host in the off-peak hours of your business.

Available update periods

The available update periods vary based on the region of your bastion host. The following table lists available update periods for specific regions.

Note During the available update period for the region of your bastion host, you can specify a custom period to update your bastion host or wait until your bastion host is automatically updated.
