In data center and cloud environment, servers used for hosting the virtual machines usually have more than one wired networking interfaces. In fact there are multiple Ethernet interfaces on each server. It is common practice to use one of the interface for ‘managing’ the host itself. This interface is usually accessible from corporate networks and administrators will use this interface for doing SSH into the server. The other interfaces are usually used for virtual machine traffic or storage traffic.
