The Value of Virtualization

4

•  Server consolidation and infrastructure optimization –  Pools common infrastructure

resources –  Breaks legacy “one application to

one server” •  Physical infrastructure cost reduction

–  Reduces hardware, real estate, power and cooling

•  Improved operational flexibility and responsiveness –  Reduces time spent on

provisioning, configuration, monitoring and maintenance

•  Increased application availability and improved business continuity –  Eliminates planned downtime

“Virtualiza*on  will  be  the  most  impac6ul  trend  in  infrastructure  and  opera*ons  through  2010.”  

—  Gartner  *Source:  Gartner,  Virtualiza3on  Will  Drive  Major  Change  in  IT  Infrastructure  and  Opera3ons  in  the  Next  Three  Years,  May  8,  2007

Application Virtualization in School Environment Challenges

§  Different students need to access different kinds of application

§  Application compatibility

§  Performance issue in old PCs

Benefits

§  Eliminates/reduces application conflicts

§  Legacy application support

§  Simplify/improve provisioning and management

§  Enable “follow me” applications

§  Reduce storage requirement

§  Good starting point to client virtualization

Centralize and virtualize with XenApp

Centralize and host in data center Easier to install, manage and support Applications and data are protected

Application Servers

XenApp Environment

Server component Web applications

Custom applications

Data Center

Desktop

Client component Web browser

Desktop applications

16

•  Universal client for IT services

•  Simple, fast, self-service install

•  Software always up-to-date

•  PCs, Macs, laptops, netbooks, thin clients, & smartphones

Deliver apps to any user, device

Desktop Virtualization

17

18

Microsoft RDS

•  RDS Server Role is installed on the Remote Desktop Session Server

•  Applications are installed on the server •  User requests an application from their desktop

19

Desktop Virtualization in School Environment

Challenges

§  Lack on manpower support

§  Difficult to unified and restricted desktop configuration

§  Hardware dependency

Benefits

§  Centralize, simplify management

Preparation on “Virtualization” - 4 Steps to adopt Virtualization

25

Step 1 : Analysis the pain point

26

Analysis the pain point in the existing system application and management bottleneck -  Servers and PCs are too old? -  Servers are too powerful? -  Higher cost on maintenance? -  Consume too much time on desktops/ applications

deployment? -  Applications are not stable in PCs to affect the

education quality?

Step 2 : Collect the information for virtualization

•  Server Virtualization

– Numbers of Servers for virtualization – Existing Servers resource utilization

•  Application Virtualization

– Numbers of Applications for virtualization – Numbers of Users for access

•  Desktop Virtualization

– Numbers of desktops for virtualization 27

Step 3 : Choose suitable virtualization technology and solution. •  Ask for a Demonstration, POC or site visit

•  Evaluate the technology and solution

•  Long-term Planning

29

Step 4 : Implementation to achieve the technology update

30

•  Start Migration Step by Step – P2V

– Server Consolidation – convert from Physical machine to Virtual

•  Virtualization to Increase Productivity
