Bare Metal can be seen as the single-tenant server and this means that you will only be taking resources of that server. The server only belongs to you. Compared with the cloud model that has multiple users that depend on the same server, bare metal will only have one customer per server
The single tendency lets you avoid noisy neighbors’ effects that are described as the user that impact the stability and performance of different users within the same servers. Through Bare metal, as you will be the only user, you are not going to witness this effect at all which is the main advantage.
