Five tips to virtual desktop ROI

2. Upgrade costs: If you have spent any time administering a virtual environment, you know that upgrading the processor or memory on an existing virtual machine consists of a couple of mouse clicks (as long as you have the resources available on the hosts themselves), versus ordering upgrades and taking the time to go out to individual desktops. This cost can be significantly reduced in a VDI environment.

3. Managing and supporting end users: With VDI, the days of connecting to a physical desktop through a myriad of clients are gone. The way you administer your virtual servers is the way you administer your virtual desktops. Just open your hypervisor console and go! Admins can interact with the boot sequence of any desktop from the comfort of their office. Issues can be resolved in minutes rather than hours and frees up valuable cycles from your support staff. Take into account the cost for this time along with the tools for remote access to add to the ROI.

4. Scalability: Unless an organization has spare physical desktops lying around pre-loaded, deploying a setup for a new user can take hours if not days. Deploying a new virtual desktop is just a matter of deploying a template with all apps pre-loaded. Just rename, add to the environment and associate that VM with the zero client sitting on the desk and requests for a user desktop is done in under 60 minutes. For any kind of large scale deployments, IT can set up 80-plus virtual desktops in one day. Scaling for seasonal or temporary users no longer means having idle physical desktops becoming more obsolete by the passing day. That is a scalable environment that adapts based on the needs of the organization. Faster deployments translate into savings.

5. Speed and performance: With VDI, all substantial network traffic lives within the data center network. The only traffic to a zero client is I/O. That 1GB file a user opens on the file server? It all goes through the data center backbone. Users typically see a noticeable performance increase and network latency is usually greatly reduced. Since many hypervisors manage memory and processor resources much better than individual desktops, users see better performance with fewer resources.
