DaaS vs Premise

In considering whether to host your own VDI solution, or to hire a cloud-hosted provider, a few considerations come to mind. Desktop as a Service (DaaS), also referred to as cloud-hosted virtual desktops (CHVD), is a great way to offset CapEx funding, and instead turn it into an OpEx expense. Contrarily, having a premise-hosted solution at your site, supported by your people (or your contractors), will give you the greatest amount of flexibility.

  1. What are the goals of your VDI implementation? For example, are you looking to make your users more mobile? Are you looking for more control over the user image–or just greater image control–or just minimizing the number of images you have to manage? Are you looking to find a way to make application distribution and updates easier to manage–and have 100% successful distributions? Or are you looking for a way to reduce costs with the whole user experience? Or are you looking for a way to implement Bring Your Own Device (BYOD) policies?
  2. Where will your data be hosted? If your data is hosted on-premise, and you’re looking to go to the cloud for VDI hosting, what’s the plan for connecting the VDI session back to the data? 
  3. How will users connect? Does your organization allow for a NetScaler-esque connection through a firewall, behind a load balancer, to a full virtual desktop, or virtual applications? If so, then you may be able to allow users to log into a web site from the Internet wherever they are, directly into the hosted solution, whether on-premise or cloud-hosted.
  4. What applications will the users be relying on? Some applications play better than others in the VDI space. For example, Office apps, web browsing, and most text-based line-of-business (LOB) applications are great candidates for a VDI solution, and even for application virtualization (see more details about virtualizing applications here and here).

Whatever your drivers, VDI can make users more mobile, give you more control over your user image, reduce the number of images to manage, make application distribution a snap, recuce the cost of the whole user experience, implement your own BYOD policies. A well-implemented VDI solution can help manage data better, be more secure, allow users greater flexibility, and give users the best experience possible. And that, really, is the bottom line: Giving the users what they need to be productive. To produce. And not have to worry about all the underlying things IT has to do in order to give them what they need.
