This document discusses virtualization and how it can help Hira, a software developer who needs to use different operating systems for his projects. Virtualization allows a single physical machine to run multiple virtual machines, each with its own operating system. This solves issues around managing multiple physical machines. The document defines key virtualization concepts like virtual machines, hypervisors, types of virtualization including desktop, network, storage and application virtualization. It also covers benefits of virtualization like improved resource efficiency, time management and reduced downtime.

2. Meet Hira, he works as
a SDE in an IT firm

3. To complete his project
he has to use Different OS
for working
Windows
Linux
Mac

4. But this often leads to
different management
issues due to multiple
operating System
Windows
Linux

10. It is a technique which
allows to share single
physical instance of an
application or resource
among multiple
organization or
customers.

14. What is
Virtual Machine(VM) ?
14

15.  They are also referred to as
guest, whereas the physical
system they run on is
referred to as the host
 Virtual machine is an
emulation or a virtual
presentation of a physical
system
Windows
Linux Mac

16. Rule of
Hypervisor
16

17.  It acts as interface between
VM and physical hardware
to ensure proper access to
the resources needed for
working
 Hypervisor is a software
that manages VMs

18. Types of
Hypervisor

19. Hardware Hypervisor
OS
Type-1/ Bare Metal
19
A Type 1 hypervisor runs directly on the underlying computer's physical
hardware, interacting directly with its CPU, memory, and physical storage

20. Hardware Hypervisor
OS
Type-2/ Hosted
Host OS
20
A type 2 hypervisor is hosted, running as software on the O/S, which in turn
runs on the physical hardware.

23. Desktop virtualization
allows us to run
multiple desktop OS in
each VM.
Types of desktop virtualization:
1. Virtual desktop infrastructure (VDI)
2. Local desktop virtualization
23

24. NV can combine multiple
physical networks into one
virtual, software-based
network, or it can divide one
physical network into
separate, independent
virtual networks.
Types of network virtualization:
1. Software-defined networking (SON)
2. Network function virtualization (NFV)
24
Network Virtualization

25. Storage virtualization uses all the
storage devices on the system to
be accessed and managed as a
single storage unit
The management and provision of
storage are made by the software.
All the storage is formed in a
shared pool from which they can
be allotted to any VM on the
System.
25
Storage Virtualization

26. Application virtualization
runs software applications
without installing them
directly into the host's OS.
Types of Application virtualization:
1. Local application virtualization
2. Application virtualization
3. Server-based application
virtualization
26
Application Virtualization

27. Paravirtualization is a
computer hardware
virtualization technique that
allows VMs to have an
interface similar to that of
the underlying hardware.
Paravirtualization involves
modifying the OS kernel. The OS
kernel acts as a bridge between the
applications and the processing
done at the hardware level.
27

28. Full virtualization is a
virtualization technique
used to provide a VME that
completely simulates the
underlying hardware.
Full virtualization differs from
paravirtualization in that the
unmodified operating system
operates completely isolated

29. Benefits of
Virtualization

30. 30
Resource efficiency, using
virtualization the maximum
computing capacity can be
utilized.
Time management, setting
up whole server from
scratch can be avoided by
using sufficient hardware
devices for virtualization
Minimum downtime,
application and OS crash
cases can be neglected by
running multiple VMs with
the same OS.
