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? Physical Hardware Virtual Machine converted

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. 5 Virtual Machines Physical Server Per

Virtualization Demo Windows VistaMac OS X Leopard Physical Server (Bobby’s Laptop) with Virtualization Software 2 Virtual Machines

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
