Should Application Virtualization Be in Your Network’s Future? – Part 2

In my previous post, I discussed 10 very important benefits that IT managers should analyze when considering application virtualization.

In today’s post, I will continue to shed some more insight on the top five limitations and downsides to this network architecture:

1) Bandwidth Requirements – Streaming apps to hundreds of users concurrently can require massive amounts of bandwidth. IT teams should make sure the cost savings from moving to virtualized apps isn’t swallowed up by extra bandwidth costs.

2) No Tolerance for Network Outages – If there is any disruption from the servers hosting the apps to the user – whether it’s within the host, in the internet connection or in the organization’s network, users are dead in the water with very limited resources to be productive.

3) Balky Apps – Some apps, particularly those that require installation of specific system drivers, work less well virtually. Some apps are better suited to virtualization than others.

4) Added Complexity – Apps from some vendors, most notably Windows, were not developed to run in a virtual environment. When there are problems, IT teams may not be able to trace whether the problem is with the app or the virtual environment.

5) More Work – If there are some apps essential to the organization that don’t function in a virtual environment, IT teams may find themselves managing two architectures with some applications running virtually and others running on users’ desktops. This scenario defeats much of the purpose of moving to a virtual environment.

Application virtualization is potentially able to benefit and boost productivity for employees and for the organization overall. However, IT teams must consider carefully the benefits versus potential downsides, and analyze application virtualization within the context of their comprehensive network plan.

It is only with a careful analysis of the organization’s network architecture and the computing needs of different types of users throughout the organization, accompanied by a detailed cost/benefit analysis, should IT teams embark on any project as impactful to a network as application virtualization.

I hope you learned a few things from this post as well as my previous post and I look forward to hearing everyone’s feedback and comments!
