When it comes to security, government organizations take every measure possible to leave no stone unturned. Yet with traditional computing, the risk of malware, viruses, hacking and even inadvertent mistakes can lead to big security headaches. By its very nature, VDI is much more secure than traditional desktops. Here's why: other information, an image is projected on their device---but the actual data resides elsewhere. application settings, installing unauthorized software or removing data on portable media. staff can destroy the golden image -- the image that contains the virtual machine, operating system, preferences, applications and setting---immediately, and create a new, secure image. the policies, such as whether you are clients, VDI is even more secure, because nothing at all can be stored on the unit itself---everything is stored on secure servers in a data center.s elsewhere. In all cases, it pays to ensure that the VDI infrastructure you implement takes security very seriously, with features centralized antivirus and anti-malware. It should also be able to comply with government requirements, such two- factor authentication. I c DI c r e ecur y Ga Chang r GAME CHANGING ECHNOLOG O MEE AGENC MI ION SPONSORED REPORT IRTUAL DESKTOP INFRASTRUCTURE "BY ITS VERY NATURE, VDI IS MUCH MORE SECURE THAN TRADITIONAL DESKTOPS." BY THE NUMBERS THE ROI OF DI AGENCIES GET THEIR MONEY'S WORTH, AND MORE Although the startup costs of moving to VDI may seem daunting, it's well worth it in the long run, experts say. tudy after study bears this out; a 2012 study from Meri alk found that even though VDI wasn't yet widely deployed, the federal government would still save $7.5 b ll from it by 2015. he study said that VDI presents a "vast, untapped savings potential." An IDC Government Insights study found much the same for state and local agencies; although it didn't cite any overall numbers, it found that the benefits always outweighed the costs. When looking at a VDI deployment, consider savings on both hard and soft costs. Hard cost savings can result from repurposing existing hardware, as well as reductions in electricity, heating and cooling needs. oft cost savings can accrue from management e ciencies, such as reduction in sta hours to support VDI versus traditional desktop computing, greater productivity, and the ability for sta to work from anywhere. he IDC study also found that VDI lowered maintenance, repair and support costs in all cases. It cited significant reduction in support calls and improved productivity as major soft cost benefits. IDC also found that government agencies were able to extend the life of existing PCs, often by two or more years, when moving to VDI. Agencies are paying attention to the ROI equation. he Ohio Department of ransportation saved money by repurposing 1,000 de k as thin clients and built on those savings with major performance improvements. he CIO of the Census Bureau has said that cost is a primary reason for the agency to move to VDI.
