Introduction

Academic institutions are increasingly using technology to support the learning process and make it more efficient. Desktopapplications are an integral part of the curriculum in the Higher Education.

Computer labs used to be the only way for students to get access to computer-based training. Today, students have personalcomputers with access to the Internet at home, and many possess a personal laptop that they bring to campus.

Application and desktop virtualization technology enables remote access to desktop applications over the Internet. There isgreat value for students to be able to access applications anytime, anywhere and from any device. This technology significantlyreduces the cost of providing application access to students as compared to traditional computer labs.

There are a number of successful implementations of this technology by colleges, but these deployments require complex ITsystem integration work. This is an obstacle for a broader adoption of this technology in the Higher Education.

Cloud computing delivers all the benefits of desktop and application virtualization and helps further reduce the cost, eliminatesthe need for investments to deploy the technology and shortens implementation timeline.

Application Virtualization Cloud ComputingComputer Labs

Annual cost In traditional computer labs, the total cost of ownership (TCO) per seat is about $500 per year. Applicationvirtualization deployed through an in-house implementation project reduces the cost per seat to about $250 per year. Withcloud computing, these costs are further reduced to about $225.

Investment With cloud computing, there is no need to allocate investment budget for technology adoption since the servicecan be procured on a subscription basis. In-house implementations, though, require about $500 investment per seat.

Implementation time An in-house executed project typically requires about 18 months in implementation time. Collegescan procure the required seat capacity from a cloud services provider almost instantly and increase it over time as the userdemand increases.

A cloud computing service provider can deliver an application virtualization solution at a lower cost while offering moresophisticated functionality, enhanced performance and increased reliability.

Application use in Higher Education

Applications

The use of applications for study purposes in a college depends, to a great extent, onthe curriculum. For example, Computer Information Systems (CIS), Engineering, andDesign make extensive use of computers and applications. In CIS courses that teachprogramming, students require access not only to applications, but also to a fulldevelopment environment where they can write code, build, deploy, test and debugtheir projects. In courses like natural science, geography and literature, softwareapplications are a complementary tool to the study process.

Content management systems and eLearning systems are often also virtualized and delivered through the same user portal.Though some of these are web applications, there is still a value in providing access to students and teachers through the sameinterface as the other desktop and client-server applications.

Students are the larger user group and their focus is primarily on accessing applications for study purposes. The faculty as auser group is primarily leveraging applications for teaching purposes.

Users

The following applications are most commonly used by colleges for educational purposes. These applications have traditionallybeen provided to students in computer labs and are now being offered via virtualization technology (this is a sample list andnot a complete holistic list of applications used today).

With application virtualization, students now have an option of accessing applications remotely over the Internet. The facultycan also use the same solution to access the needed applications, teach in classes or review student homework.

Application access over the Internet

User Experience



6/20

Standard Citrix Application Window

Standard Citrix Login Screen

After successful login to the portal, the user is shown the icons of relevant applications in the browser window. An examplein the figure below shows Microsoft Office and other general purpose applications grouped in one folder. The portal provides

access control mechanisms to enable access only to the applications which are approved for that specific user.

The user clicks on one of these icons and an application opens up in a separate window; he or she then interacts with theapplication through the keyboard and mouse. The receiver plugin installed on the client device transfers the keyboard andmouse commands over the Internet to the application running on the server. The user interface screenshots from theapplication are then transferred over the Internet and displayed on the end users computer. Under optimal networkconditions, the user looks at the graphical interface and may not even notice any difference as compared to an application thatis physically installed on the client device.

In order to access applications, users go to a specified URL and install a receiver plug-in. Then, they use a Web browser tologin to the portal, select the needed application from the list and launch it. The access to the portal is controlled by ausername and password based authentication mechanism.

Application Licensing

The student can work with the application, create an output file and save it to a sharedfolder located in the datacenter. The teaching professor can use the same access to the

application, select the same file from the shared folder, open it, review the work done bythe student and make any necessary changes.

Apart from applications, students also have access to a Windows Explorer utility which letsusers access their files in My Documents folder and move files between the folders. Atypical use-case for assignment submission is a shared folder, where students and facultycan submit and view all the assignments. Students are also able to download the files totheir computer or email files from the shared folder.

Today, most software applications are licensed on a per user or per device model. With application virtualization, there is aneed to change licensing agreements to a concurrent user-based pricing model. This requires colleges to get in touch with theapplication vendors and amend the licensing agreements.

Most Independent Software Vendors (ISVs) are accepting the concurrent user-based pricing model at the same price level.Typically, the planned number of concurrent users per application stays the same as the number of applications previouslyinstalled in the computer labs. For some applications, the number of licenses may increase, and for other applications, thedeployed count is reduced according to demand. Accordingly, the cost of application licensing typically remains the same afterapplication virtualization is implemented.

Access anytime Traditionally, students could access the software applications only in thecomputer labs on campus. Though colleges try to make these computer labs available from earlymornings until late evenings, it is still limited to lab administrators availability to open and close thelab. Now, students can access their applications 24x7 - any time of the day, any day of the week.

Access from anywhere Students were required to go to campus to access the softwareapplications, even if they needed to do a minor change or modification to the file. Now, studentscan work remotely from home or in cafs via Wi-Fi hotspots.

Benefits to User GroupsStudents



8/20

IT Department

Digital classroom Computer labs are used either for teaching or self-study purposes. Certaincourses require each student to work on an individual computer in the classroom during the class.Given that more and more students have a personal laptop and bring it to campus, the need forclassic computer labs with pre-installed applications is diminishing. For certain courses, it is evenmandatory for students to have a personal laptop. Computer labs are then converted to aclassroom where students can connect their laptops to power and access applications.

Faculty

Online curriculum with online applications Teachers are now able to use desktop applications which were previously not

accessible remotely to students, improving the teaching methodology and its effectiveness.

Speed of adding new applications Traditionally, the faculty was dependent on the IT staff to install applications in computerlabs. This required significant management efforts and was a challenge. Now, as applications are centrally installed and deliveredvia virtualization, requests for additional applications are implemented and rolled out to users in no time.

Reputation gain The colleges have seen significant gain in their reputation as an institution that cares for the students anduses technology to improve the education experience overall.

Reduced desktop administration cost Because of central install and management of the OS,there is a significant reduction in PC administration effort.

Reduced application management overhead Application virtualization technology eliminatesthe need to install and manage applications on multiple computers, a task that can be verycomplex and time consuming.

Efficient use of application budget An application virtualization solution gives exact reporting

Easier access to students assignments With online resources centrally located, students are able

to submit their assignments online. In turn, this helps the faculty to manage these submissions. Thefaculty also benefits from being able to access applications and files from anywhere and at anytime.

on application usage. Colleges can now rearrange budgets to procure more licenses forapplications that are widely used and reduce licensing spend on less frequently used applications.

Device independent Students are able to use almost any device to access applications. It can be a desktop, laptop, tablet, oreven a smartphone. Application virtualization also allows running Windows applications on the Macintosh end user devices.

Cost of buying applications To complete their homework, traditionally, students would have to buy some software to workon their own computer at home. Now, students can work with applications from home without the need to buy them. Thecost of software applications with a student discount is in the range of $50-$100 or even higher. If the application is used onlyfor one course or to gain a basic understanding of its capabilities, there is no practical reason for the students to buy anapplication.

Improved file management With an integrated central storage system, students can access their files centrally through thesame system that enables application virtualization. Faculty members get remote access to the same files in the shared foldersand can review the homework without any hassle of managing files across different devices.

The Wipro research team created a reference case based on information collected from multiple colleges with an objectiveto represent the most typical in-house implementation experience. In this reference case, a college has about 10,000 students,2,500 faculty and college administration staff, and originally has about 500 desktops in computer labs. About 100 applicationsare provided to students for study purposes. The implemented application virtualization solution is able to support up to 700concurrent users and the computer labs can be downsized to 100 desktops, offering a total of 800 seats.

Implementation Options

Reference Case

The traditional way of deploying application and desktop virtualization solution is to execute an in-house system integrationproject. In this case, the college IT team takes responsibility for defining scope, creating the overall project plan, doing a costestimate, identifying and securing the required budget, executing the project and rolling out the solution to the user base. Thisis how traditionally most of the IT projects have been done in the IT industry.

Though both application and desktop virtualization technology have matured substantially over time, the road to a successfulimplementation is a complex task. Colleges, generally, need a System Integration partner who can guide them through thevarious phases of planning and execution.

System Integration

Reduced PC hardware requirements When most students bring their own laptops or are able to access applications froma home computer, the number of PCs in computer labs can be significantly reduced.

Extended PC refresh cycle The older Lab PCs can be re-used as thin client devices in combination with application anddesktop virtualization.

Low cost Thin Client devices There are cases when computer labs are still required, for example when students dont havelaptops and must rely on the college-provided infrastructure. Given that most applications are virtualized and delivered overthe network, there is no need to have a full scale desktop with pre-installed applications anymore. A cheaper category of ThinClient devices can be used.

Reduced power consumption Reducing the number of desktops reduces power consumption, especially with the usage ofThin Clients in the labs to replace remaining desktops. Some colleges reported up to 80% cost savings towards energy bills.

Faster implementation of new applications A centralized implementation methodology enables IT teams to deploy the newapplications much faster and make them available to faculty and students in just a few days.

Optimal utilization of software licenses IT teams are able to monitor the usage pattern of applications and optimize thenumber of software licenses procured.

Secure computing environment Application virtualization technology provides complete isolation of client devices fromapplications and data, providing increased security while enabling wider collaboration.

Improved data backup and disaster recovery With a central storage solution along with application virtualization, the ITteam is able to establish better backup and disaster recovery policies and procedures.

Cloud computing is a big driving force in the IT industry today. Software as a Service (SaaS) is one of the cloud models whensoftware is provided as an online service over the Internet in a scalable fashion. There is no need to maintain an in-houseinfrastructure with servers, storage, and network elements, and there is no need of an upfront investment.

User access to applications over the Internet can be enabled from a service provider datacenter. Colleges will need to bringtheir application licenses, while the solution overall will be offered as a service. Students will have a portal to access applications.After logging in, students will get access to the applications that are registered with the service for that specific college. Theservice can be sized based on the number of seats required; in essence, the maximum number of concurrent users.

Additionally to the data center, an appliance can be located on campus and connected directly to the Local Area Network(LAN). The appliance will include all the necessary hardware, software and applications, and will be managed remotely by thecloud service provider. It can deliver certain application and desktop virtualization technology on premises.

An appliance can be used for multiple purposes:

Cloud Computing

Server, storage, and network hardwareNetwork configuration and monitoringServer virtualization software and operating systems

Application and desktop virtualization software stackInfrastructure management softwareApplication virtualization testing toolsClient devices

The various dynamics between hardware, software, networking, storage, web portal, and other components create a complexenvironment to design, deploy and manage. One of the most important elements of the overall system design is to create theright balance between the application workload and compute power for the planned number of concurrent users. There arebest practices and reference architectures to deploy these solutions, but the technology is quickly evolving, so the olderreference designs become sub-optimal within a short period of time.

For a successful implementation, the implementation team needs to be familiar with the latest technology across severaldisciplines:



11/20

This section describes the project plan for implementing the Application access over the Internet solution in-house. The

approach outlined below is a System Integration (SI) effort by a college IT department, in partnership with a specialist vendor.In most cases, such a partnership is a pre-requisite due to high complexity of the technology stack overall and requiredexperience in architecting, configuring, and tuning the application and desktop virtualization solution.

Typically these implementations have two tracks of activities and are done in a phased manner.

PlanningThe planning phase is focused on developing the overall business case and implementation plan. Funding sources need to be

identified. Reaching out to different software vendors to amend the licensing terms is a time consuming exercise. The planningphase extends until completion of the POC and a go ahead decision to do a pilot implementation.

Proof of ConceptThe IT team needs to identify an SI partner with competency in application virtualization, evaluate alternatives, select theapplication virtualization technology, and then establish contractual relationship with the virtualization technology vendor. An

evaluation of technology options during the POC is in itself a project with full life cycle from hardware procurement,installation of software to testing and analysis. Procurement of hardware alone often takes several months.

Full scale deploymentFull scale deployment is focused on scaling the application virtualization solution up to the targeted number of concurrentusers. While technically the solution has been proven during the pilot, it is still a separate project that needs to be executed

through all its life-cycle steps.

User educationUser education starts with the pilot deployment, working with the pilot user group. After the full scale deployment is complete,

the focus changes to driving broader user adoption. It takes a lot of marketing and user training effort to deliver informationto students and to educate a broader population of students.

Achieving user adoption is not an easy task. This can fail on minor technology issues, incomplete solutions, or performancechallenges with the solution. The best practices in user education include brown bag sessions, announcements in computerlabs, converting computer labs to the new way of accessing applications, awards to pilot users, and train the trainer sessionswith teachers.

Pilot deploymentThe goal of the pilot phase is to design a technical solution and roll it out to an initial group of about 100 users. The objectiveis to gather experience with running a production environment and understand user behavior. Only a subset of applications isrolled out during the pilot. Creating solution architecture is a highly skilled and very critical activity that requires a combinationof hardware architecture knowledge and familiarity with the latest server, storage and networking technologies. In depthknowledge of virtualization software is essential for proper performance tuning of the solution.

The overall speed at which the application and desktop virtualization technology deployment happens depends on severalfactors. In many cases, the timeline is determined by the iterative nature of learning the technology, exposing it to users andmaking modifications to the solution based on user feedback. Another driving factor in this process is the budgeting cycle, sincefunding for deploying the full capacity is often spread out over several years.

In our reference case, the total cost of providing applications to students through computer labs is approximately $250,000per year. The main cost items associated with application virtualization are computer administration, hardware and softwarecosts and electric power. With application virtualization, the total cost can be reduced to about $200,000 per year, while thenumber of seats can be increased from 500 to over 800.

A detailed analysis of the annual operational cost (in our reference case) between traditional computer labs infrastructure andapplication virtualization solution is provided below.

Hardware and Software Most students can now access applications using their own laptops, so the number of desktops in

computer labs is reduced from 500 to 100. Another element of savings is that the remaining desktops are used primarily asthin client display devices and their life span is expanded from four years to eight years. In our reference case, a server solutionwith application virtualization and sufficient storage capacity is created. Application virtualization and management software isan additional cost component.

Computer Administration There are 3 FTE (Full Time Equivalent) computer administrators required to service 500desktops in computer labs and installed applications. After application virtualization is implemented, the total effort ofmaintaining applications and managing the desktops reduces to only 0.5 FTE. There is an additional effort of 0.5 FTE to managethe new server infrastructure. Savings through application virtualization provide funding for technology upgrades in other areasand, hence, freed up FTEs can be allocated to those strategic projects.

The investment required to create an application virtualization solution in our reference case is in the range of $400,000. Thisincludes two main cost items:

Given that the overall number of seats is about 800, the investment to implement application virtualization is about $500 perseat, which is half of the per seat investment in physical computer labs.

Hardware and software: An application virtualization solution requires a server infrastructure, high performing storageand networking components, with the overall cost of about $200,000.Consulting and FTE cost: It takes a few years to implement the solution and reach the targeted levels of user adoption.External consulting is required due to complexity of the solution overall. An IT department typically invests severalperson years into implementation and user education. These costs all together can easily account to an additional

$200,000.

Investments

Students are using their own personal laptops and the college doesnt need to provide any end user computing devices.An application hosting solution is replacing the traditional computer labs.The central server that replaces the individual desktops offers the computing power that is shared in a better way andcan service more end users.By moving applications to a centrally managed server solution, there is no need for administrators to install, upgrade,and apply patches to multiple desktops across the campus one at a time. These changes are made to only one instanceof the golden image, leading to a substantial reduction in the desktop administration effort.

With 500 desktops in traditional computer labs and the overall cost of $250,000, the cost per seat is about $500 per year.These costs include desktop hardware depreciation, computer administration and electric power. With applicationvirtualization, the total number of seats implemented is typically higher than the eliminated seats in computer labs in order toprovide students more flexibility and allow faculty users to use the same solution. In this reference case there are 800 seats.The overall annual cost is $200,000 and accordingly, the cost per seat is coming to $250 per year - an overall 50% reduction.

There are several fundamental reasons why the seat cost with application virtualization is becoming substantially lower:

Power A typical desktop and monitor together consume about 100 Watt of electric power. Reducing the number ofdesktops in computer labs leads to a sizeable reduction in power consumption. For accurate accounting, we need to consideradditional power consumption by the server solution and an increased number of students with laptops on campus. Overall,the power consumption can be reduced by half, leading to additional savings.

Deployment

While the investment to implement application virtualization is large, colleges may not always require the full amount in formof additional funding. With the reduction in the number of desktops and increased life expectancy of the existing desktops, alarge portion of the desktop refresh budget can be redirected towards the server solution. Reduction in computeradministration efforts gives bandwidth to the existing staff for managing and implementing the application virtualizationsolution.

This section describes the project plan for the Application access over the Internet solution implemented leveraging a cloudcomputing model.

There are two main tracks of activities:

Planning

The planning phase is focused on developing the overall business case and work plan. Funding sources also need to beidentified. The overall duration of the planning phase can be substantially shorter, since there is no need to wait for results ofthe POC on technology evaluation. Piloting with a small user group can start from day one and, given that the service has beenfine tuned based on feedback from other customers, it shall be a much smoother overall experience.

Cloud Computing System Integration

Overall, the timeline of introducing a Cloud Computing Service to students and reaching the targeted level of user adoptioncan be much shorter than in a customized System Integration approach.

Colleges can start offering the service in a matter of 3 months. The overall adoption time frame can be reduced to about sixmonths. The only remaining time-consuming activity is amending the licensing agreements with application vendors.

IntegrationWhile for basic use of the service, no technology integration is required, a larger college may step onto a path of integratingtheir Student Information System to address more advanced requirements on user access rights and automation of the overalladministration. To optimize network performance, colleges may also choose to deploy WAN acceleration, a technical solutionfocused on reducing latency between the service provider datacenter and the on-campus network.

User EducationThe college IT team can dedicate more time to user education and leverage materials and methodology from the cloudservices provider to roll out the technology across the student population.

Annual cost per seat

In our reference case, the annual operational cost of providing applications to students through computer labs is approximately$250,000 per year and with an application virtualization solution, it will be about $200,000. In a cloud computing service model,these costs can be further reduced to about $180,000 per year.

The analysis of the total cost of ownership in our reference case of an application virtualization solution implemented in-houseand cloud computing service is provided above.

Hardware and Software The server solution, being located in a central data center, can achieve better utilization levels andhence the cost of hardware per user is reduced from $120,000 to $108,000.

A cloud solution requires a customer portal for user account management, billing, reporting and other functions and it comes

as an additional item in the cost structure of the cloud service provider.

Computer Administration In the cloud solution, most server administration tasks are automated over time and accordinglythe cost of infrastructure management goes down from $75,000 to $67,000.

Power Although there will be some reduction of power consumption due to better hardware utilization, this will not impactthe calculation substantially.

The annual total cost of ownership with a cloud computing solution is approximately $180,000 per year. Given that we areaccounting for a total capacity of 800 seats, the overall cost per seat is reduced to approximately $225 per year.

The main reduction in operational costs comes from the fact that a cloud solution doesnt require new implementation eachtime a new customer is added. The technology implementation is done once in a scalable, multi-tenant architecture andsupports additional customers without any substantial changes.

With a cloud computing service model, the required investment will be very minimal. There is no infrastructure investmentrequired. There will be some expenses in program management and driving user education, yet, in most cases, they can bedone by leveraging existing staff or with support from the cloud services provider.
