VDI Basics and Deployment Strategy for Enterprise Executives

By CIOReview | Friday, July 22, 2016

Operating System (OS) can sometimes sink itself into overdrive when antivirus updates or hot fixes are on the run. And for a growing enterprise it becomes a laborious work to streamline the turmoil occurring on thousands of computer. This state of confusion can be suppressed by transforming the current environment to Virtual Desktop Infrastructure (VDI).

VDI! What is it?

VMware, a cloud and virtualization service provider corporation developed the practice of hosting a desktop operating system within a virtual machine running on a centralized server or data centre. And this Virtual data centre is termed as VDI. This desktop virtualization is powerful enough to enable the availability of fully personalized desktops for each user along with all the security and operability provided by the centralized management. VDI’s boon to customer’s is the offerings—reduced cost, flexibility, and mobility in any device regardless of place and time. Further, VDI does not evoke single point of failure.

How to tread for successful VDI deployment? Get an overview of the existing infrastructure:

A study and observation of the existing infrastructure is a must for a CIO, and this can be done by accessing the virtual, remote and storage environments. The study should also involve evaluation of the current technology trends in the market—Internet Small Computer System Interface (iSCSI), Network Attached Storage (NAS), and Direct Attached Storage (DAS). 

Analyze physical desktop and user’s environment:

Draft a report of the current desktop environment conditions and configurations—networks, Central Processing Units, storage. Further, prioritize workers based on user experience requirements—user profile, single versus multiple desktop needs, granular Universal Serial Bus (USB) redirection, printing requirements, audio profile (one-way or two-way), and monitor support.

CIOs also need to do additional assessment to analyze the current environments executable size, device drivers installed per application, total number of application users, and average load time. Along with these assessments, it is important to envisage the upcoming VDI requirements apart from the current metrics.

Select optimum VDI solution:

Technology market has myriad solution providers—VMware, Citrix, Microsoft, Oracle but it is important to select the best mix of technology that adapts and suites organizational needs. While selecting, keep an eye on the remote protocol options and look at the impact across network, security and performance.

Request a pilot test:

It is veritably been said to “Look before you leap.” So before investing, request a demo of the solution by defining the various test metrics and framework as necessitated by the organization. After assessing the reports from the pilot, develop a blueprint of the VDI framework that offers good practices, and supports in achieving organizational milestones.

Compile a business case:

Once all these study and analysis is completed, compile the study and assessment reports. Additionally along with reports, CIOs need to develop a business case document of the project and present it to the stakeholders (like CFO’s). The documentation should be rich in information regarding the current mechanisms and challenges surrounding the physical desktop management. These challenges may also include the complexities involved in the existing operating system. The information should also be able to display the current operating system, application patching, Individual access authority, maintenance frequency, and compliance policy. Further, calculate costs incurred with the current system and the costs retribution during the time of refreshing hardware and downtime.

CIOs can also use Optimal Operating Expense (OPEX) savings available in the market today for a profound presentation of the VDI project
