Smoothing the Transition to Virtual Desktop Infrastructure
Virtual desktop infrastructure can benefit organisations by allowing more centralised, standardised deployment and management of virtual desktops. Because everything is stored and managed in data centres, this desktop virtualisation delivery method allows IT to complete all troubleshooting, security patching and adding of applications without affecting the end user’s computer. VDI also allows easier security and backup of data through the data centres and faster deployment of desktops to remote users.
That doesn’t mean transitioning to VDI is a cakewalk. To avoid having your VDI solution turn into a hassle, designate the right people to lead the build-out and piloting of the implementation, get user input and conduct an audit of the applications you want to include in the VDI image.
Carefully decide who will manage the project
VDI projects will bring together the IT staff managing servers in the data centres and the staff managing the desktops. Some elements of the project can get lost in translation between these two groups. Both teams have very different roles involving management of different resources, and sometimes these employees aren’t even based out of the same office.
One of the ways around this potential struggle is to designate one person to oversee both groups – such as the CIO directly – to ensure each is doing its bit to get the project done. The designated manager can make sure desktop staff is given access to the data centre and its resources to complete the project, for instance. Organisations may also be able to avoid these issues all together by choosing an IT outsourcer to design, build and implement their VDI solution.
Keep the users happy
In a recent ZDNet story, research firm Longhaus cautions against IT departments designing their VDI plan and pilot without their end users in mind. Any transition to virtual desktops will bring about pain points and some disgruntled users who were happier with the previous setup. If accessing critical applications becomes a major problem during the pilot phase, and if users can no longer customise their desktops, the IT department will risk losing employee buy-in for VDI.
To help keep most of the end users happy, organisations should choose the most enthusiastic VDI supporters to try the pilot first. These users can then be VDI evangelists for the rest of the company and show, from a user perspective, how the technology works and how it can benefit the organisation. Allowing staff to move between the pilot system and the production system will also cut down on user down time and allow users to keep working as the organisation makes the transition to VDI.
Put the right applications on the image
Some organisations falter with VDI when it comes time to build the image. IT must choose which applications to put on the image, but this is easier said than done if the team leading the project doesn’t knows which apps are the most relevant and used. The worst-case scenario is that IT mistakenly leaves critical apps off the image, resulting in users being unable to access the systems necessary to do their jobs.
A way to work around this is by having the IT department take a thorough inventory of all the applications in use prior to building the VDI image. This task may involve assessing if any apps were installed locally on certain users’ computers to ensure every person in the organisation will have access to the apps they need. Taking the time to complete this task now can help avoid project delays and user issues when you get into the pilot phase.
