Introduction

• The Reports 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?
• Its 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

  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 (continued)

• Current status of virtual infrastructures
• Hardware advancements
• Running multiple-operating systems
• Meeting business needs

11
Benefits

• Use fewer computers
• Does the job of multiple computers
• Allows you to use your hardware sources more
  efficiently
• Gain better desktop management

12
Security Benefits

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

13
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

14
Limitations

• Challenge
• Main purpose of virtualization
• Hosting hardware choices

15
Capacity Planning

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

16
Hidden Costs

• Could easily incur
• Power costs
• Heat costs

17
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

18
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 machines operating system
  handle different roles independently

19
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

20
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
