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.
