running at only 10 or 15 percent of total
processing capacity.
85 or 90 percent of the machine’s power is
unused

power, and possibly IT staff.
the practical aspect of virtualization:
• Minimize hardware costs
• Provide disaster recovery
• Consolidate idle workloads
• Balance loads
• Test software
• Centralize server management
• Conserve power
• Deploy servers faster

12. Virtual server (system) is like a physical server, is
dedicated to a job or jobs for which it is designed.
Configuring a virtual server is much the same as
configuring a physical dedicated server.

system from local hardware to a remote server
system.
remote desktop is accessed by using some
lightweight client in the form of a small or minimal
operating system

Network segment, or isolate, traffic into separate
(VLAN) broadcast domains
VLANs are usually created using intelligent switches, but you can also
create them with:

technology, it has the effect of making
hardware more important.
