![What is Virtual Desktop Infrastructure?
11
Virtual Desktop Infrastructure –it is a concept not a product, an architecture
for running virtual desktops on an ESX server.
Leverage the advantages of the data center for the desktop
Virtual desktop as a concept, separates a PC desktop environment from a
physical machine.
The model stores a “virtualized” desktop on a remote central server
instead of on the local storage of a PC client.
In a virtual desktop model the programs, applications, processes, and data
are stored and run in a centralized server environment.
End users connect to a remote desktop, but have a local experience
Enables a scalable highly available, highly accessible user environment
This allows users to access their desktops on any capable device, such as
a traditional personal computer, notebook computer, smartphone, iPad, or
thin client.

be circumvented with next software release around min 2013. Windows
7 didn’t encounter any significant issue.
Given that the architecture is very complex than server virtualization,
we recommend to start VDI implementation with phased approach and
build the environment incrementally.

Business Case Of Desktop Virtualization
This document summarizes a proposal for implementing a virtual desktop infrastructure (VDI) at ABC Inc. It includes an executive summary highlighting benefits of VDI like simplified provisioning and centralized management. It then provides an overview of the current desktop challenges, typical corporate desktop models, and advantages of VDI. The objective is to evaluate the financial and operational impacts of VDI solutions. The analysis compares the 5-year total cost of ownership for the current (BAU) environment versus a VDI solution. It finds that while the VDI solution has higher initial capital costs, it provides overall savings of $66,000 over 5 years through reduced operating expenses.

- 4. Executive Summary Overthe past years many organization have realized the benefits of server virtualization. A favorite technology to dramatically compress server footprint and lowering both capital and operational expenditures. IT organizations today are looking for new ways to address their desktop challenges (Quick provisioning, Windows 7 migration, Patching, Security). More recently, desktop virtualization has emerged as a serious topic of discussion. The concept of consolidating hundreds, or even thousands, of desktop images onto a single server platform has great appeal to many organizations. Gartner recently estimated that the number of virtualized desktops could grow to 660 million by 2012. Some reasons for the mass appeal are the promise of: simplified provisioning of desktops centralized desktop management and support streamlined new desktop OS upgrades secure remote access and Disaster recovery 4

- 12. Key Points aboutVirtual Desktop Infrastructure 12 Tasks like procurement of desktop computer hardware, deploying or patching desktop operating systems, updating antivirus signature, securing data, and desktop support become more and more challenging as the size of an organization grows, and the disbursement of employees across multiple locations increases Replacing all or a bulk of an organization’s computer workstations with thin client terminals and managing the client OS and applications in a centralized location is something most organization would love to be able to do. As smartphones, tablets, and other mobile devices become the data access and communication tools of choice in the work place, the systems needed to support this new generation of mobility are changing. Companies supporting bring your own device programs need to deliver corporate desktops and applications to various mobile devices in a secure way, and VDI does just that.
- 13. Advantages of VirtualDesktop Infrastructure 13 Reduced cost in purchasing desktop computers, as thin clients often last two to three times longer than a desktop computer Centralized Client OS Management Rapid Client Deployment Reduction in desktop support costs Reduction in electricity costs, as thin client computers use only a fraction of amount of energy that is used by a desktop computer. Improved Data Security and centralized data storage Improved worker productivity because of reduced PC downtime and the ability to access desktops from multiple locations; Fewer Application Compatibility Problems than with Terminal Server and Citrix, as users have their own, single user OS. Better business continuity and disaster recovery capabilities. Secured access to corporate data across a wide range of corporate and employee owned devices including Mac, Windows and Linux devices as well as iPad and Android tablets.
- 14. Objective of theDesktop Virtualization The purpose of this desktop virtualization and application is to provide decision makers a framework to evaluate the potential financial and operational impacts of desktop virtualization solutions on the organization. The aim is to show the benefits and savings, through calculations and assumptions used in the analysis. Note: All simulations and calculations in the slides ahead are based on renown virtualization software, which is considered as one of the most renowned virtualization suites available in the market.
- 15. Virtual desktops arenot for everyone. For example, employees who works in marketing, and Technical team; These type of employees use laptops and mostly spend much of their time using graphics and video editing software, or use specialized I/O devices, are usually not good candidates for virtualization. They also need to install applications themselves for their activities and need administrative privileges and high-performance desktop, may not be a good fit for VDI. But many workers are well served by virtual desktops, including “day extenders” that use laptops only between working hours. The following examples describe standard virtual desktop usage scenarios: Ideal Users For Desktop Virtualization Organization Descriptions Call center Employee class who relies on only office and web applications seems to be the right candidates (Microsoft’s Virtual Desktop Infrastructure ).Employees get a session when they arrive that can be permanently or temporarily assigned. Temporary desktop assignments are ideal for application access, reducing the overhead of provisioning More desktops. The system ensures there are sufficient desktops available for employee access. Outsourced staff Outsourced staff performs tasks while sensitive applications and data remain within control of the organization. Organizations can control when users can access the system and where information can go. Development & test Instead of providing multiple PCs to employees for development and test activities, provide multiple virtual desktops, each provisioned with a temporary lease or permanently. Users can access multiple PCs through thin client.

- 24. Key Drivers forVirtualization VDI is unlikely to result in any significant $ savings. However, its usefulness is in the "soft" benefits Higher availability Improves Manageability Operations Automation & Effectiveness Shortens provisioning time. Environmentally friendly Data centralization on SAN results in better data protection & backup Enhanced Compliance and Data Security Enables “Thin Client” compute capability – Workplace independence from the Data Center in terms of distance and connectivity B/W constraints Enables ‘Bring Your Own Device’ policy to deliver corporate desktops and applications to various mobile devices (i.e. Mac, Windows, iPad and Android tablets) in a secure way.
