This template deploys an Azure Firewall with Availability Zones in a virtual network.
Azure Firewall is a managed cloud-based network security service that protects your Azure Virtual Network resources. It is a fully stateful firewall as a service with built-in high availability and unrestricted cloud scalability. You can centrally create, enforce, and log application and network connectivity policies across subscriptions and virtual network. Azure Firewall uses a static public IP address for your virtual network resources allowing outside firewalls to identify traffic originating from your virtual network.
The service is fully integrated with Azure Monitor for logging and analytics.
Azure Firewall is currently a managed public preview that you need to explicitly enable using the Register-AzureRmProviderFeature PowerShell command. Learn more at https://docs.microsoft.com/en-us/azure/firewall.
