What would be better run on vm or on bare metal?

metricbeat getting large set of data, about billion document a day, 100+ gig data,  
data will be feed by three logstash

spec I was making was 8 data node, three master and three logstash. data node with ssd or nvme.  
will that better or spinning up vms.

nothing on cloud all local.

yes I have some money for it  
this is what I was thinking dell sever with nvme 2TB for 8 data node.  
master don't need anything small systems.  
logstash no storage but same hardware as datanode

Will that better or buying three/five loaded systems and spin up docker on it? I am only talking about performance wise which one is better?

Bare metal is usually more performant.
