3. VMware software provides a completely virtualized set of
hardware to the guest operating system.
The VMware virtual machines become highly portable
between computers, because every host looks nearly
identical to the guest.
A systems administrator can pause operations on a virtual
machine guest, move or copy that guest to another physical
Hardware seen as pool of resources available on-demand on
an arbitrary basis.
4. History of Virtualization
Initially developed in the 60’s to leverage the usage of
mainframe computers. Each user sees the machine as fully
dedicated (timeslot multitasking).
Deployed from the late 60’s to the mid 80’s, then abandoned in
favor of the emerging mini and microcomputer architectures.
VMWARE appears after successful reutilization of the
virtualization concept for a (non-standard) multiprocessor
prototype. Standard software could be run using middleware.
Investigation team founds VMWARE in 1999. First desktop
product in the same year, server version in 2001.

8. Virtualize data centers
VMware vSphere leverages the power of virtualization and
enables transformation of Classic Data Centers (CDCs) into
Virtualized Data Center (VDC), which is the foundation for cloud
computing infrastructures. vSphere aggregates the underlying
physical x86 based hardware resources across multiple systems
and provides a pool of virtual resources. The VMware vSphere
consists of the components shown on this slide. VMware
vSphere also provides additional modules and plug-ins, such as
VMware Distributed Resource Scheduler (DRS), VMware High
Availability (HA), and VMware Data Recovery.
9. Virtualize data centers
VMware vCenter Converter is a highly robust and
scalable enterprise-class migration tool that
automates the process of creating virtual machines from
physical machines and other virtual machine formats (for
example virtual machines created using Microsoft
VMware vCenter Converter lets users quickly, easily, and
affordably convert Microsoft Windows and Linux-based
physical machines to VMware virtual machines. It also
converts virtual machines between VMware platforms.
Encapsulation : strong isolation,
independence between guest

replicated, transmitted (migrated),

from templates, ready with
configuration and data.

migrated a large number of servers into VMware
virtual machines. We saw how
well the applications performed, and we never
looked back. At this point, all
new programs are built using VMware software. It’s
become our server hosting
platform of choice.“

13. Case Study- Welch's
Challenge: Server consolidation and optimized management
Solution: VMware virtual infrastructure provides centralized management,
reporting, performance and high availability.
Saved more than $100,000
Saved $75,000 this year in switch costs
Expect to save $250,000 by the end of the year
CPU utilization increased from 5-10 percent to 50-60 percent
Reduced deployment time from 4-6 hours to 15-20 minutes. Server procurement also used to
take 2-4 weeks
VirtualCenter cut costs and maximized ease of server management
