For deploying VM-Series firewalls in high availability (HA), it is crucial to ensure that both firewalls in the HA pair have identical licenses and subscriptions to ensure feature parity and uninterrupted service during failover. Additionally, both firewalls must be deployed on the same type of hypervisor to ensure compatibility and proper synchronization of state and configurations between the active and passive units.

In AWS, VM-Series firewalls support only active-passive high availability (HA) configuration. This means that one firewall is active and processing traffic, while the other remains passive and takes over in the event of a failure. This design consideration ensures continuous availability and reliability of firewall services in the AWS environment.
