Then, it will be balanced across Fault Domains as far as possible. Within each Fault Domain, the virtual machines chosen for removal will be the newest ones that are not protected from scale-in. <br><br> **OldestVM** When a virtual machine scale set is being scaled-in, the oldest virtual machines that are not protected from scale-in will be chosen for removal.
