Virtual desktop infrastructure (VDI) is the practice of hosting a desktop operating system within a virtual machine (VM) running on a centralized server. VDI is a variation on the client/server computing model, sometimes referred to as server-based computing.
Utilization of Same Image
The first benefit of VDI is that desktops can use the same image. The OS, as well as applications that are installed, decreases organizational and support costs. Images will need to be tested as new applications are introduced, and either additional images will need to be created or adjustments will have to be made to the current build. Also, depending on your model, if you use persistent desktops, incremental storage space will be needed for VDI servers since user needs vary, i.e. saving private settings if users are allowed to install their own applications.
More Options for Expensive Desktop Upgrades
While an investment in server hardware and storage infrastructure may be required, keep in mind that everything will be hosted in the data center, therefore, there may not be a need for a huge collection of standard PCs in the office.
If staff is working within a mobile, bring-your-own-device environment, you can run the same environment on tablets as you would experience on high-end desktops. This model also opens the door for the client desktops and Chromebooks that can be replaced in minutes instead of hours.
These options will deliver the required environment to all users uniformly and give flexibility to administrators to adjust the environmental variables such as memory allocation and storage per environment on the fly.
Management of a Single OS Can Reduce Costs
Because everything is hosted in the data center, admins will have to install drivers, patches and applications only once and every user – depending upon that image – benefits from the update. Also, it’s important to make sure all the administrators learn everything about the VDI software.
Troubleshooting Problems is Easier
Today, support staffs have a tedious task of running out to physical PCs. This has been reduced by different models of VDI. As images can be accessed from any linked workstation, any user facing hardware trouble on their usual systems can go to another one and access their data and applications simply by logging in and having their policy based apps and rules pushed to them.
Data is More Secure
Another important benefit is that data and images will be in the safe zone in the data center. You can now utilize standard data center tools to manage the security.
