This document discusses various types of virtualization including cloud virtualization. It defines virtualization as transforming hardware into software which allows multiple operating systems to run as virtual machines. It describes full virtualization using a hypervisor, para-virtualization where guest servers are aware of each other, and server virtualization which allows VMs to run on different physical servers. The document outlines benefits of cloud virtualization including cost savings, increased control, and simplified disaster recovery.

5. What Is Virtualization ?
• Virtualization is a
Technology that transforms
hardware into software.
• Virtualization allows to run
multiple operating systems
as virtual machines.
– Each copy of an operating
system is installed in to a
virtual machine.

6. Full Virtualization
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 OS.

7. Para Virtualization
The para-
virtualization
approach is a little
different than the
full virtualization
technique, the guest
servers in a para-
virtualization
system are aware of
one another.

8. Virtualization Allows Transformation
of a Server for Multiple Applications

9. Server Virtualization

10. Server Virtualization
• The VMs created on one physical server
can be run another physical server.
• Failure in one physical server will not
effect the VMs installed on that.

11. Storage
Virtualization is the
next frontier in
Storage Advances
that aims to provide
a layer of
abstraction to reduce
complexity

12. Software
virtualization is the
virtualization of
applications or
computer programs

14. INTRODUCTION
 Virtualization represents the logical
view of data representation- the power
to compute in virtualized environments.
It is a technique that has been used in
large mainframe computer for 30+
years. It is used to manage a group of
computers together- instead of managing
resources separately.
Cloud Virtualization Technology

15. Virtualization Defined
Virtualization is an abstraction layer that
decouples the physical hardware from the
os to deliver greater IT resources utilization
and flexibility.
Virtualization can bring the following
benefits
● save money
● increased control
● simplify disaster recovery
Cloud Virtualization Technology

16. Cloud Virtualization Technology
Benefits
1. Traditional benefits
a) server consolidation
b) “Green IT” - reduced power and cooling
2. Additional Benefits
a) increased availability/business continuity and
disaster recovery
b) efficient application and desktop software
deployment and
Maintenance
c) dynamic and extensible infrastructure to rapidly
address new business requirements

17. Current Virtualization Initiatives
Here is a list of different virtualization
initiative actively pursued in industry
Today
● Virtual Networking
● Virtual Disk
● Consolidated management
● Vmotion
● Svmotion
● Dynamic load balancing
● Zones

18. Cloud Virtualization Technology
Virtual Machine
Often called Virtual environment or container.
A Virtual machine is a server environment that
does not physically exist but is created within
another server.
For user interacting with a VM is seen or
presented as a physical machine providing
access to an operating system and machine
resources like CPU memory, hard disk and
network.

19. Cloud Virtualization Technology
Virtualization Technologies
Two major types of virtualization
technologies widely used are
● Hardware Virtualization
○ virtualizes the server hardware
● OS virtualization
○ virtualizes application environment

20. Cloud Virtualization Technology
Hardware based Virtual Machine
(HVM)
● Hardware based Virtual Machine or
Hardware assisted Virtualization ( HAV) is
done possible by using new features
developed by Intel and AMD
● These new features include Intel
Virtualization Technology (VT-x) and
AMD’s AMD-V

21. 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

22. DetailedDesign
It introduces many changes into the
environment, and ensures that the platform can co-
exist and interact with existing infrastructure.
The purpose of detailed design to set naming and
security standards, define the disk and network
structure. It includes the following
● Security and Administrative Model
● Back up methodology
● VMware service console configuration
● implement tables and configuration setting

23. Summary
This focuses on cloud virtualization and also
covers other flavours of virtualization. It
also covers software components used for
managing virtualization process
