    Ashka123Yes, to have VMs in separate Azure datacentres within a region you need to use Availability Zones:
    https://docs.microsoft.com/en-us/azure/availability-zones/az-overview#availability-zones

     

    An Availability Zone has "one or more" datacentres- so in some cases you might by chance end up spread across different physical buildings within that Zone, but to guarantee different datacentres you need to use the Availability Zones.

Hi 

As said in Microsoft documentation :

An Availability Zone is a physically separate zone, within an Azure region.

There are three Availability Zones per supported Azure region.

So you need to verify the Availability zones for the region in wich you deploy Azure resources .

Then you should select Availability options : Availability zone

And you'll be able to select the main zone 1 2 or 3 . You'll notice that you can choose only one in the same time but it's fine .In case of datacenter outage you should be OK since data are replicated to other datacenters .
