Installing kali linux as os on a external ssd

Hi. Im using KALI LINUX in both VMWARE AND VMWARE FUSION(MAC) . But i like much more Kali than MACOS so i was wondering instead of carrying my MACBOOK LAPTOP i can have KALI on a external SSD and use it as i would use a it as main OS with changes,files, modifications and more been saved into it. And boot it in any pc instead o using a latop for it.

Also i was thinking on maybe replacing the MACOS with KALI or having KALI in a cloud server ( but i think cloud may not be all that good.

Thanks for replys
