I'm looking for clarification on the pricing for Azure Firewall as I seem to be finding conflicting information.
As I understand it, when deploying Azure Firewall I can choose to have it within a single AZ or across multiple AZ's. There is a 99.95% SLA in a single AZ or 99.99% in more than one AZ.
So, in order to get 99.99%, I effectively need to deploy/pay for a pair (two) units?
I normally check out some blogs on Azure resources and I spotted this post (and I've seen others with similar information)
There is no additional charge for running firewalls in an availability area. However, inbound/outbound data transfers to or from an availability zone incur additional costs.
It would seem that I don't get charged for the additional unit?
Also, I've had a look for Az data transfer costs
Which states it is free.
Maybe I should just be ignoring this and similar blogs? Hoping that someone might be able to shed some light!
