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
