Introduction

• The Report’s Objective– Prove that virtual infrastructures can be implemented into

information systems using the system development life cycle stages

• Focus of Our Presentation– Introduce a complex topic by going through the basics

– Demonstrate how virtualization technology works

– Information about Virtual Infrastructure

– Benefits of Virtual Infrastructures

– Limitations of Virtual Infrastructures

– Suggestions and Recommendations

Virtualization• What is server or computer virtualization?

– Basic idea: converting a physical computer to a virtual machine• What is a virtual machine?

– It’s a computer (except that its virtual).– Operating system running on software that emulates hardware

(virtual hardware).– Hardware parts of a typical computer:

• Processor• Memory• Hard Drive• CDROM• Network card• Etc…

– Convert all hardware to software• All previously listed hardware are now software• Operating system still thinks its running on hardware

Virtualization• What is server or computer virtualization?

– Basic idea: converting a physical computer to a virtual machine

• What is a virtual machine?

No hardware just a virtual machine

Virtualization• What do we do with this virtual machine? Where does

it run?– The virtual machine runs a physical computer using the

virtualization software.– A bunch of virtual computer on top of one physical computers.

Virtual Infrastructure

• What is it?• Three components

– Single-node hypervisors (physical component)

– Virtualization-based distributed system

– Automations solutions

Virtual Infrastructure Setup

Virtual Infrastructure (continued)

• Current status of virtual infrastructures

– Hardware advancements

– Running multiple-operating systems

– Meeting business needs

Benefits

• Use fewer computers• Does the job of

multiple computers• Allows you to use

your hardware sources more efficiently

• Gain better desktop management

Security Benefits

• Safe and secure virtualization platform– More than 100,000 customers trust it– Many virtualization security resources

Cost Benefits

• Reduces cost– Cost reduction from combining server outputs– Main reason why businesses choose to

virtualize their physical infrastructures

• Reduces space– Put everything you need all in one computer

Limitations

• Challenge• Main purpose of

virtualization• Hosting hardware choices

Capacity Planning

• Definition• Place virtual machines correctly• Job of virtualization vendors & software developers

Hidden Costs

• Could easily incur– Power costs

– Heat costs

Necessary Changes

• Dynamic Mobility– Split a single physical

hard drive into multiple logical or “imaginary” drives

• Storage must be agile and manageable– Cooperate with other

storage networks in the infrastructure

Linear Performance

• Start with a small infrastructure and grow it over time– Increase resource utilization as the company

gets bigger

• Make better use of the operating systems– Make each virtual machine’s operating system

handle different roles independently

Specialists/Expert/Personnel

• You need the following personnel– System Engineer– System Administrator

• Only a few people are needed to run a virtual infrastructure– They need to have strong skills for network

applications and storage optimization

People Recommendations

• Have people (most important component) who can maintain, update, and monitor the infrastructure

• System administrators need to be competent– To monitor the infrastructure– To update the infrastructure– To be able to recover from failures– To carry out maintenance procedures
