With an increasing number of personal computers introduced in schools, enterprises and other large organizations, workloads of system administrators have been on the rise due to the issues related to energy costs, IT expenses, PC replacement expenditures, data storage capacity, and information security, etc. However, Application Virtualization (AV) has been proved as a successful cost-effective solution to solve these problems. In this paper, the analytics of a Virtual Desktop Infrastructure (VDI) system will be taken into consideration for a campus network. Our developed system will be introduced and justified. Furthermore, the rationality for these improvements will be introduced.

1. Introduction

Most of system administrators have a large number of tedious tasks, for example, regular updating software and anti-virus feature database, installing patches of different Operating Systems (OS). All of the manual tasks makes the system administration work error-prone, inefficient, tedious and time-consuming. Even if there were only a few failures when the system administrator installs patches, it would leave the security to the hidden danger.

Virtual Desktop Infrastructure (VDI) is a very effective solution to solve this kind of problem. VDI offers a flexible desktop service by managing and delivering applications, so as to provide the enterprises significant benefits as follows (Herrod, 2006).

  • Save the cost.

  • Reduce registry and system bloat on user’s PC.

  • Simplify software deployment.

  • Centralize software updates.

  • Simplify OS deployment.

The objective of the project in this paper is to facilitate IT professionals in easy installation and management of software on the L-College computers in a high-security environment. Two clear and accurate findings will be justified in this paper,

  • Design and development of a VDI system for the L-College to overcome the problems existing in their networks.

  • Ensure the stability of this VDI system in the physical to virtual conversion process.

This project conducts four pieces of research work associated with a college’s new VDI system. (1) Requirement analysis and design of the VDI system. Throughout the paper, general demand of the college, functional requirements of the VDI system and performance requirements of the VDI system will be introduced. After that, the VDI system will be divided into four modules, namely client-side module, application management module, system resource management module and user data management module. (2) The implementation of the VDI system. The college’s network topology, network configuration, virtual machine installation and applications installation will be implemented in this paper. Also, this paper will present the optimized resource allocation of the VDI server by using quantitative calculation rules of the physical servers’ consolidation. (3) Reliability and usability of the VDI system. Our investigations associated with the reliability problems in a virtualization infrastructure will be committed. This paper will emphasize the reliability of the Physical to Virtualization (P2V) method in a virtualization processing. (4) Testing. A functional testing, a capability testing and a performance testing will be completed before end of this paper. After the testing, an optimal result will be given as the outcome.


There are a variety of methods having been used to create a virtual desktop system. Baratto et al have proposed a mobile virtual desktop computing hosting infrastructure (MobiDesk). In a MobiDesk system, there is a thin virtualization layer, which is used to extract users’ application stream from a specific client terminal, and transfer the processing of all of the applications to the server logically. Another layer in MobiDesk is a virtualization layer. This layer enables users to take application resources from the server by executing the selected application and deploying the virtual desktop on users’ hardware. The MobiDesk system is a cluster system with a proxy server. The architecture of the MobiDesk system which encompasses a proxy server, couple session servers, a network file system (NFS), a storage server, and a number of display devices (Baratto, Potter, Su, & Nieh, 2004).
