Public Preview: Attach and VMs to and from Existing Virtual Machine Scale Sets

With Attach and Detach support for Virtual Machines (VMs), you can easily bring your VMs to Virtual Machine Scale Sets (VMSS) with Flexible Orchestration Mode and a Fault Domain Count of 1. After attaching a VM to the VMSS, it’s considered as part of the scale set and benefits from scale set features like Autoscale, Instance Repair, Automatic OS Upgrades, and more. Attaching the VM to the VMSS requires no downtime.

Should you need to troubleshoot your VM outside of the scale set, you can simply detach the VM from the VMSS and investigate further.
