High Availability
Resolution

High Availability (HA) is a configuration in which two identical Palo Alto Networks firewalls are placed in a group and their configurations are synchronized to prevent a single point to failure on the assigned network. A heartbeat connection between the firewall peers ensures seamless failover in the event that a peer goes down. Setting up the firewalls in a two-device cluster provides redundancy and allows business continuity.

 

The following table provides a list of valuable resources on understanding and configuring High Availability:
