Public preview available for Azure Firewall’s Parallel IP Group update support | Microsoft Azure updates

Azure Firewall now allows users to update multiple IP groups concurrently, a feature that was previously unavailable. This backend update enables users to update up to 20 IP groups referenced in a firewall policy simultaneously. This enhancement is particularly beneficial for administrators who need to make configuration changes quickly and at scale, especially when utilizing a DevOps approach. By leveraging templates, ARM, CLI, and Azure PowerShell, administrators can now streamline the update process. For more information on this new feature, refer to the articles on Parallel IP Pool Updates (Preview).
