CN-Series as a Kubernetes CNF in HA mode of deployment supports which type of HA with session and configuration synchronization?

In the context of deploying a CN-Series as a Cloud Native Firewall (CNF) in a Kubernetes environment, the active/passive high availability (HA) model is characterized by one node taking on the active role while the other remains in a standby mode. This means that the active node is handling all traffic and processing, while the passive node is configured to take over in the event of a failure of the active node.

The active/passive configuration allows for session and configuration synchronization between the two nodes, which is crucial for maintaining service continuity and minimizing downtime. When a failover occurs, the passive node can quickly become active and continue operations without losing any sessions or configurations, thanks to this synchronization.

This model is particularly effective for ensuring reliability and predictable behavior in a firewall deployment, where maintaining the state of connections and current configuration is critical. Thus, it ensures that both the session data and configurations are replicated and ready to switch immediately in case the active node experiences an issue, providing seamless failover and continuity of service.
