Virtualization 1.x: Near term Virtualization 2.0: Emerging Virtualization 3.0: Future
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
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
§ Enable thin-client computing
§ Simplify device support and management
§ Lower service desk costs
§ Provide business continuity
20
VDI Architecture Overview
Scalability Optimized for desktop delivery Deliver 10’s to 1,000’s of desktops
Availability
Ensure zero downtime Protect against unplanned downtime Quick recovery from unplanned downtime
Reliability
Ensure optimal desktop performance Protection from planned downtime

§ Used in Library or Kiosk
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
