Cluster Settings

The Cluster Setting is used to configure High Availability (HA) in the Active-Passive (AP) or Active-Active (AA) mode across multiple instances. This setup ensures that if the primary (active) instance fails, a secondary (passive) instance automatically takes over to minimize downtime and maintain service continuity.

HA Settings

How to Use:​

  1. Go to Stack > Instances > Cluster Settings
  2. Configure your settings
  3. Click Save Changes
