create one VM in multiple zones

Question

Hi, when we create a single VM from the Portal, we now see the option to create the VM in multiple zones. As my VM is a standalone VM, I choose the value "No infrastructure redundancy required".

However, from Azure Advisor, I got the following recommendation:

"HighAvailability","recommendationImpact":"High","recommendationName":"Use Availability zones for better resiliency and availability".

For a single/standalone VM, I do not understand what does it mean using Availability zones. Because if we choose the "Availability zones" option, then at least two VMs will be created and to benefit from the load balancing between the two VMs, then we need to create a VM Scale Set.

Thanks for feedback, Regards.

Hi

creating your VM or any other resources with Infrastructure redundancy means that in the event of an outage in a specific datacenter, your VM will be available from other datacenters.
