2. VIRTULIZATION
• Virtualization technology is the process of
creating a virtual platform with the aid of
virtualization software.
• These software’s acts as a layer between
the primary system and the secondary
system or virtual systems.
• It allows the virtual system to access the
resources of the primary system such as
RAM, ROM, Storage, CPU, Network etc.

4. Virtualization - One Server for
Multiple Applications/OS

5. Types of Operating System
Host Operating System:
• The operating system actually running on
the hardware itself.
Guest Operating System:
• The operating system running in the
simulated environment
likeVMware,virtualbox,ect.

6. Virtualization Techniques
1. Para-virtualization
2. Full-virtualization
3. OS level-virtualization

7. Para-virtualization
• The para-virtualization approach is a little
different. Unlike the full virtualization technique,
the guest servers in a para-virtualization system
are aware of one another.
• A para-virtualization hypervisor doesn't need as
much processing power to manage the guest
operating system

8. Full virtualization
1. Full virtualization uses a special kind of
software called a hypervisor. The
hypervisor interacts directly with the
physical server's CPU and disk space. It
serves as a platform for the virtual
servers' operating systems.

9. OS level-virtualization
• An OS-level virtualization approach
doesn't use a hypervisor at all.
• Instead, the virtualization capability is part
of the host OS, which performs all the
functions of a fully virtualized hypervisor.

11. Types of Virtualization
1. Server virtualization
2. Desktop virtualization
3. Network virtualization
4. Storage virtualization

12. Server/Hardware Virtualization
1. Hardware Virtualization is nothing but creating
a completely new system on the existing
primary system via virtualization that acts as a
real computer with an operating system it is
also termed as a virtual machine.
2. For e.g. creating a virtual machine via means
of hypervisor or virtual machine manager with
Ubuntu Linux operating system on a computer
which is already running a Windows OS.

13. Desktop Virtualization
• The Phrase ‘Work from Anywhere’ is practically
possible because of Desktop Virtualization it
provides work convenience and security.
• It enables us to remotely access the data from
anywhere and anytime through any device.
• It provides a lot of flexibility and feasibility for
employees and the data is safe and secure as it
is stored at a centralized location.

14. Desktop Virtualization

15. Network virtualization
• Network Virtualization is nothing but
virtually pooling & managing all the
available network resources such as IP’s,
Switches, Routers, NIC’s, VLAN tags etc.
via means of tools such as routing tables
in real time and each channel is
independently secured and distinct from
one another.

16. Storage virtualization
• It is the pooling of physical storage from
multiple network storage devices into what
appears to be a single storage device that
is managed from a central console.
Storage virtualization is commonly used in
storage area networks (SANs).

17. Hypervisor
• Hypervisor, also known as a virtual
machine monitor, is a process that creates
and runs virtual machines (VMs).
• It allows some of the multiple operating
systems to share a single host and its
hardware.
• This hypervisor manages requests by the
virtual machines to access the hardware
resources like RAM , CPU etc.

18. Types of Hypervisor
• 1) Type-1/Native/Bare Metal Hypervisor.
• 2) Type-2/Hosted Hypervisor.

19. Type 1Hypervisor
• Type 1 hypervisor is installed directly on
bare-metal hardware, it doesn't require
an additional OS, it is the OS, even it it is
a light or minimal OS.
• EX. Xen, Microsoft Hyper-V
• System is thin, the hypervisor has direct
access to the HW.

20. Type 1Hypervisor

21. Type 2 Hypervisor
• Type-2 Hypervisor is also known as
Hosted Hypervisor.
• Type-2 hypervisor runs on a host operating
system that provides a virtualization service.
• Type-2 Hypervisor is installed on an
operating system and then it supports in
other operating systems.
• EX. VirtualBox and Vmware Workstation

22. Type 2 Hypervisor

23. Virtual Box
