Where does the VMs place, if does not assign those VMs to Availability Zone.

Answer 1

Hello Lucas Deng

Welcome to Microsoft Q&A Platform, thanks for posting your query here.

If you don't select any Availability Zone when you deploy a VM, then they are placed within the Azure region where the virtual machine is created.

Azure regions consist of one or more data centers that are geographically located near each other and connected by a low-latency network. When a VM is deployed within a region, Azure's infrastructure platform automatically distributes the VMs across multiple physical servers within the region, based on the provider's load balancing algorithm.

Hope this helps.

Answer 2

Hi,

If you create a Virtual Machine in an Azure Region that has Availability Zones, but you don't specify a zone, it will be placed in one of the zones automatically by Azure.

For example, say you use the portal to create a VM in North Europe region and select "No infrastructure redundancy required" on the Basics tab. Azure will automatically place it in logical Availability Zone 1 or Zone 2 or Zone 3, however, when examining the properties of the VM it will show blank for Availability Zone.
