Dedicated Servers | Windows & Linux Hosting Hypervisors Vs Bare Metal Servers: a Beginner’s Gu | Page 13

 Improved mobility: The VM’s structure has been designed in a way that it operates
independently separate from the underlying hardware. This enables it to have the ability
to roambetween local and remote servers that have an abundance of resources.
 Optimization of hardware: Hypervisors have the ability to optimize hardware to a
greater extent. It allows virtual machines to run on their own by dividing resources into
separate entities. In addition, with virtualized servers, hypervisors make VMs super
mobile to a level that the underlying hardware is rendered irrelevant.
 Security: Virtual environments are quite secure too. Even if the virtual instances haven’t
been physically separated, they are technically isolated from each other. Sure, they may
be on the same server but they have no knowledge of each other. So yes, the noisy
neighbor effect may be witnessed but the hypervisors are secure.
