Implementation

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 updated at the same time. Build high-availability into
your application architecture by colocating your compute, storage,
networking, and data resources within a zone and replicating in other
zones.
When you create a scale set, consider these parameters.

For all Virtual Machines that have two or more instances deployed across
two or more Availability Zones in the same Azure region, we guarantee you
will have Virtual Machine Connectivity to at least one instance at least
99.99% of the time.
For all Virtual Machines that have two or more instances deployed in the
same Availability Set, we guarantee you will have Virtual Machine
Connectivity to at least one instance at least 99.95% of the time.
For any Single Instance Virtual Machine using premium storage for all
Operating System Disks and Data Disks, we guarantee you will have Virtual
Machine Connectivity of at least 99.9%.
