Deploy VDI Now:10 Reasons to Make the Switch Instead of Replacing Your PCs

By Frank Ohlhorst on 2010-07-23



Many small and medium enterprises are on the verge of a major PC refresh to replace all those PCs that have long stayed past their prime -- many four-years-old or five-years-old, clogged with malware, and running hot. Those poorly performing desktop PCs are chugging under the weight of new applications and can't take advantage of the performance enhancements offered by new operating systems. But before making the expensive leap into new desktops with all of the associated costs, administrators should ask themselves – “is there a better way?” The answer may very well come in the form of VDI (Virtual Desktop Infrastructure), where the physical desktop PC is replaced by a virtual PC running in the datacenter and the desktop session is delivered to an endpoint via a TCP/IP connection. Many vendors offer VDI solutions that work with a range of endpoints, including thin clients, zero clients, netbooks, notebooks and traditional PCs. Those vendors include VMware, VDIWorks, Citrix and many others, offering plenty of choices that should meet most any requirement. More importantly, VDI opens up a world of opportunities and offers a few significant advantages over the traditional rip and replace system of refreshing desktop PCs.

VDI speeds the desktop provisioning and deployment process. Creating a new desktop PC is a fast and simple process using VDI tools, where a new virtual machine can be built using cloning utilities, application virtualizations and many other tools.

VDI eases desktop management. Administrators have full control over who can access a virtual machine, what changes can be made and when the virtual machines are available.

VDI reduces desktop hardware costs. Existing desktop PCs can be used as clients for VDI solutions, eliminating the need to purchase new desktop hardware to deploy new operating systems and applications.

VDI supports alternative end points. Administrators have the choice of deploying VDI solutions with thin clients or zero clients, reducing hardware overhead and desktop support needs.

VDI eases desktop support. Help desk personnel can directly access a virtual machine to trouble shoot problems or rebuild a new VM in a matter of minutes with provisioning tools.

VDI improves security. Administrators can easily lock down virtual desktops, control access to virtual machines, shutdown peripheral access and prevent proprietary data from traversing the network.

VDI eliminates the need for local backups. User PCs no longer need to be backed up, since their VMs are stored in the data center and backed up there.

VDI allows users to work from most anywhere. Traveling or remote users can access their VDI desktops remotely -- anywhere they have a reliable internet connection.

VDI eases system migrations. VDI offers virtual desktops to end users, those virtual desktops are created and maintained in the data center – when it comes time to upgrade a user, the only thing an administrator needs to do is assign a new virtual desktop to the end user.

VDI can put the personal back into personal computing. VDI can be setup to store user’s settings, local files and preferences, allowing those settings to follow a user from machine to machine, giving users the level of desktop customization they are used to, regardless of the client device they are using.
