12. Virtualization

Virtualization is a proven software technology that is
rapidly transforming the IT landscape and
fundamentally changing the way that people compute.

Today’s powerful x86 computer hardware was originally
designed to run only a single operating system and a
single application, but virtualization breaks that bond,
making it possible to run multiple operating systems
and multiple applications on the same computer at the
same time, increasing the utilization and flexibility
of hardware.
12

13. How Virtualization works?

Virtualization lets you transform hardware into
software. Use software such as VMware to
transform or “virtualize” the hardware resources
of an x86-based computer—including the CPU,
RAM, hard disk and network controller—to create
a fully functional virtual machine that can run its
own operating system and applications just like a
“real” computer.
13

14. How Virtualization works?

Multiple virtual
machines share hardware
resources without
interfering with each other
so that you can safely run
several operating systems
and applications at the
same time on a single
computer.
14

15. What is a Virtual Machine?



A virtual machine is a tightly isolated
software container that can run its own
operating systems and applications as if it
were a physical computer. A virtual machine
behaves exactly like a physical computer and
contains it own virtual (ie, software-based)
CPU, RAM hard disk and network interface
card (NIC).
An operating system or applications can’t
tell the difference between a virtual machine
and a physical machine. Even the virtual
machine thinks it is a “real” computer.
Nevertheless, a virtual machine is composed
entirely of software and contains no
hardware components whatsoever.
15

16. VMware approach

The VMware approach to virtualization inserts a
thin layer of software directly on the computer
hardware or on a host operating system. This
software layer creates virtual machines and
contains a virtual machine monitor or
“hypervisor” that allocates hardware resources
dynamically and transparently so that multiple
operating systems can run concurrently on a single
physical computer without even knowing it.
16

17. Benefits Virtualization (1)



Virtualization essentially lets one computer do the job
of multiple computers, by sharing the resources of a
single computer across multiple environments.
Virtual servers and virtual desktops let you host
multiple operating systems and multiple applications
locally and in remote locations, freeing you from
physical and geographical limitations.
In addition to energy savings and lower capital expenses
due to more efficient use of your hardware resources,
you get high availability of resources, better desktop
management, increased security, and improved disaster
recovery processes when you build a virtual
infrastructure.
17

18. Benefits Virtualization (2)




Compatibility: Virtual machines are compatible with all
standard x86 computers
Isolation: Virtual machines are isolated from each other
as if physically separated
Encapsulation: Virtual machines encapsulate a
complete computing environment
Hardware independence: Virtual machines run
independently of underlying hardware
18

19. Virtual Infrastructure

a virtual infrastructure is a dynamic mapping of physical
resources to business needs. While a virtual machine represents
the physical resources of a single computer, a virtual
infrastructure represents the physical resources of the entire IT
environment, aggregating x86 computers and their attached
network and storage into a unified pool of IT resources.
19

20. Benefits of Virtual Infrastructure

By decoupling the entire
software environment
from its underlying
hardware infrastructure,
virtualization enables the
aggregation of multiple
servers, storage
infrastructure and
networks into shared pools
of resources that can be
delivered dynamically,
securely and reliably to
applications as needed.
20

21. Benefits of Virtual Infrastructure

This approach enables organizations to build a computing
infrastructure or Data Centre with high levels of
utilization, availability, automation and flexibility using
building blocks of inexpensive industry-standard servers.

22. AppLogic Example: A Virtual Data Centre



AppLogic is a grid operating system which enables utility computing for running
and scaling web applications.
AppLogic captures and operates on the logical structure of the application.
This makes it very easy to assemble, deploy, monitor, control applications visually
in a browser.
