Support for High Availability on VM-Series on Azure

Traditional HA configuration is not relevant in Azure. For HA, use cloud-native load balancers such as the Azure Application Gateway.
To ensure availability, you can Set up Active/Passive HA on Azurein a traditional configuration with session synchronization, or use a scale out architecture using cloud-native load balancers such as the Azure Application Gateway or Azure Load Balancer to distribute traffic across a set of healthy instances of the firewall. For details, see Deploy the VM-Series and Azure Application Gateway Template.
