Starting from ZStack Cloud 4.7.21, you can configure NTP time servers for the Cloud to sync the clock of the time servers with all nodes of the Cloud. This allows you to manage your platform time efficiently and ensures the stability and reliability of time sync.

You can add up to 2 internal time servers and 2 external time servers for the Cloud.

The latest system time is displayed on the Cloud. If you configure time servers, this time is auto synced with the time servers. If the system time has large difference with the time servers, you can manually sync time by force to save your time.

Starting from ZStack Cloud 4.7.21, version detection is available. This feature periodically detects the latest version and provides information about the version number and the highlights if the latest version is available. You can upgrade to the latest version based on your needs.

If you enable version detection, you can configure the version pull strategy. You can pull production environment recommended versions or technical preview versions and specify the auto detection duration by day, week, month, or year. By default, the auto detection is implemented once every month.

Before you configure the strategy, make sure the management node is connected with the Version Maintenance Center. After the configuration, the version info detection and push is implemented based on the strategy. You can also implement manual detection and modify or disable the strategy on demand.

Starting from ZStack Cloud 4.7.21, you can generate a system self-signed certificate or import a 3rd-party SSL certificate to the Cloud. After you successfully configured the SSL certificate, you can log in to the Cloud UI via HTTPS protocol, which ensures that the data transmission is effectively encrypted for the Cloud.
