Question on Azure Firewall

Question

Hello,

Could you please help me with following:

1. Are there any fixed charges for Azure firewall? If not, what is per deployment hour in Pricing calculator for firewall.
2. When I create Azure SQL database, I can see the expected monthly bill for Azure SQL but same is not the case with Azure firewall. Why for some Azure services expected billing is not displayed during creation of those resource/service
3. I see Premium firewall is cheaper than Standard - kind of strange. Is it possible to downgrade a Premium firewall to Standard firewall? Will there be any downtime ?

Appreciate your insightful response, thank you !!

Hello @anil kumar ,

Welcome to Microsoft Q&A Platform. Thank you for reaching out & hope you are doing well.

Please find the answers for your questions below:

1) A fixed hourly fee will be charged per a firewall deployment regardless of scale. In addition, data processing fee is billed per deployment for any data processed by your firewall. Please refer : https://azure.microsoft.com/en-in/pricing/details/azure-firewall/

2) Some Azure resources have data processing fees added with the fixed deployment or monthly charges which completely depends on the amount of the data processed by a customer and it differs from customer to customer, hence estimating this charge is not possible. So, estimated/expected billing is not displayed during creation of these resources/services.

3)Azure Firewall Premium is currently in public preview. This preview version is provided without a service level agreement, and it's not recommended for production workloads. Certain features might not be supported or might have constrained capabilities. And hence, you may find the pricing to be cheaper than Standard. Once the Premium Firewall goes GA, the pricing may change.

You cannot downgrade a Premium firewall to Standard firewall but you can migrate an Azure Firewall Standard to Azure Firewall Premium Preview to take advantage of the new Premium capabilities.
