Availability Set in Availability Zone Azure

Question

I've read somewhere that availability sets can be deployed in availability zones, however I can't find the doc again. Now I cannot find the doc and can't find anywhere to validate what was written. So my question is can an availability set be deployed in an availability zone, and if there's any docs on how to do it?

Thanks in advance.

Answer 1

In an Availability zone you automatically get the functionality of an Availability Set.

An Availability Zone in an Azure region is a combination of a fault domain and an update domain. For example, if you create three or more VMs across three zones in an Azure region, your VMs are effectively distributed across three fault domains and three update domains. The Azure platform recognizes this distribution across update domains to make sure that VMs in different zones are not scheduled to be updated at the same time.
