High availability (HA) is a configuration in which two firewalls are placed in a group and their configuration is synchronized to prevent a single point of failure on your 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 you to ensure business continuity.

You can now deploy the CN-series-as-a-kubernetes-CNF in HA. This mode of deployment supports only active/passive HA with session and configuration synchronization.

When you deploy the CN-Series-as-a-Kubernetes CNF in HA, there will be two PAN-CN-MGMT-CONFIGMAP, PAN-CN-MGMT, and PAN-CN-NGFW YAML files each for active and passive nodes.
