What Exactly is Virtualization?

How Will Virtualization Benefit Me?

Getting Started: vSphere Hypervisor

Who is VMware? What are We Trying to Solve?

Agenda

Virtualization Defined

Virtualization ● virt·tual·iz-a-tion ● [vur-choo-uhl-iz-ey-shuhn]

–noun 1. Today’s x86 computer hardware was designed to run a

single operating system and a single application,

leaving most machines vastly underutilized.

Virtualization lets you run multiple virtual machines on

a single physical machine, with each virtual machine

sharing the resources of that one physical computer

across multiple environments. Different virtual

machines can run different operating systems and

multiple applications on the same physical computer.

2. Something only VMware can do well :)

Virtualization Defined

For those more visually inclined…

Traditional Architecture Virtual Architecture

ESXi: 3rd Generation Hypervisor Architecture

VMware GSX

(VMware Server)

• Installs as an

application

• Runs on a host OS

• Depends on OS for

resource management

• Installs “bare metal”

• Complete HW

management

• Relies on a Linux OS

(Service Console) for

running agents and

scripting

• Installs “bare metal”

• Complete HW

management

• Management tasks are

moved outside of the

hypervisor (3rd party

integration via APIs and

CIM; scripting via vRCLI)

to simplify operations

and maintenance

Some Benefits of Virtualization

Consolidation - One-time event that moves existing applications

onto a fewer number of servers

Containment - An ongoing effort to virtualize new applications

and manage growth of existing ones

Availability – Introducing virtualization to increase application

availability and data recoverability

…there are many more benefits of virtualization

Capital costs

The Results are Transformational

“Strategically, virtualization leads

inexorably down a path toward agility,

flexible sourcing and cloud computing.”
