You can have a shared cluster for compute, management and edge, but sizing and design has to be considered. It is usually easier and more secure to segregate at least a management+edge cluster separate from compute. Having everything on prepared hosts with only N-VDS just makes it even harder when you have Edge VM, as you have an N-VDS connected to another N-VDS, although it works without any problems.

If you have hosts with multiple NICs I usually like to have 2 for vDS/vSS and 2 for N-VDS. This way things are much simpler.
