Generally Available: Prescaling in Azure Firewall

Azure Firewall now supports prescaling, a feature that enables admins to provision and reserve capacity units in advance to handle expected traffic loads – such as seasonal peaks or planned business events. This helps to ensure consistent throughput, faster scaling response, and greater control over capacity. Key highlights: * Proactive planning: Pre-allocate capacity to meet demand spikes and critical workloads * New observability metric: View current and historical capacity usage in the Observed Capacity Metric to provide strategic insight into planning * Flexible billing: Pay only for the provisioned capacity units, with the flexibility to adjust as your needs evolve. Prescaling is available for Azure Firewall Standard and Premium SKUs in all public regions. **Learn more:** * about [Azure Firewall monitoring data reference documentation](https://nam06.safelinks.protection.outlook.com/?url=https%3A%2F%2Flearn.microsoft.com%2Fen-us%2Fazure%2Ffirewall%2Fmonitor-firewall-reference&data=05%7C02%7Cv-sanyaibe%40microsoft.com%7C0c4a0ad4827945d1214908de0cda8e68%7C72f988bf86f141af91ab2d7cd011db47%7C1%7C0%7C638962329999949193%7CUnknown%7CTWFpbGZsb3d8eyJFbXB0eU1hcGkiOnRydWUsIlYiOiIwLjAuMDAwMCIsIlAiOiJXaW4zMiIsIkFOIjoiTWFpbCIsIldUIjoyfQ%3D%3D%7C0%7C%7C%7C&sdata=Z5OKHLbdHsDtaaUu2V6cug5ucCYsinoQ66dMlLec2xA%3D&reserved=0 "Original URL: https://learn.microsoft.com/en-us/azure/firewall/monitor-firewall-reference.
