Configuring a failover or redundant Apex
If you need a high degree of availability for Apex, then enable the Apex redundancy feature. Redundancy, also known as failover, helps maintain a high “up” time for your Apex system.
If your primary Apex system becomes unavailable for any reason, then the secondary Apex system automatically becomes active and available for dashboards. By having a failover Apex system, you can help ensure that maximum availability is maintained.
