What is Virtualization?
What is Hardware Virtualization?

3.  Hardware virtualization allows to run several
operating systems on a unique machine. This is
done due to a specific software called “Virtual
Machine Manager” (VMM).
 In hardware virtualization there are two things:
 Host machine
 Guest machine
-The software that creates a virtual machine on the
host hardware is called a hypervisor or Virtual
Machine Manager.

5.  Full Virtualization:
Almost complete simulation of
the actual hardware to allow
software, which typically consists
of a guest operating system, to run
unmodified.

6.  Some but not all of the target environment is
simulated. Some guest programs, therefore,
may need modifications to run in this virtual
environment.

7.  A hardware virtualization DR environment
will involve hardware and software
protection solutions based on business
continuity needs

8. Tape backup for software data long-
term archival needs This common method
can be used to store data offsite but can be a
difficult and lengthy process to recover your
data. Tape backup data is only as good as the
latest copy stored. Tape backup methods will
require a backup device and ongoing storage
material.
Whole-file and application
replication The data is replicated on a
different disk partition or separate disk device
and can be a scheduled activity for most servers
and is implemented more for database-type
applications.

9.  Virtualization lets you reduce the complexity
of your IT infrastructure by maximizing the
utilization of your physical computing
resources. But you still need to purchase and
maintain servers and software.
 Pros
 Real time sharing
 Testing and learning
 Portable
 Cons
 Resource hungry.
 Not compatible
