Generally Available: Attach and detach of VMs on Virtual Machine Scale Sets for a single fault domain

With attach and detach support for Virtual Machines (VMs), you can easily bring your existing 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. Likewise, you can use this functionality to move VMs between scale sets. 

This feature is now generally available in all regions.
