Slow VDI adoption rate could get a boost from Desktop as a Service

Cost and management challenges have kept many companies from embracing VDI, but VDI adoption could see an increase as DaaS matures.

VDI adoption rates are up for debate. Depending on whom you ask, you might hear that virtual desktop infrastructure (VDI) is common across all types of enterprises, or you might be told that nobody is deploying virtual desktops.

To help you get a better sense of where VDI is today and how it will -- or won't -- grow in the future, we posed this question to desktop virtualization experts:

Will VDI ever be mainstream?

Ed Tittel and Earl Follis: Over the last two years, VDI has generated significant buzz online and in the minds of IT pros trying to distinguish the VDI meat from the sizzle -- and hype -- that so often surrounds this subject.

One IT manager friend at a large company in Houston who's been running a Citrix VDI implementation for several years told us he has struggled to keep his virtual desktops running smoothly. His issues have ranged from a virus that once infected every virtual desktop in his organization to difficulties finding and keeping qualified technical staff familiar with VDI to arrange for the care and feeding of that infrastructure.

Another roadblock to VDI adoption has been IT budgets constrained by several years of cuts or reductions. VDI requires a more robust back-end infrastructure than more traditional thick clients. Also, that infrastructure is not cheap. VDI with support for disconnected user desktops -- those that are not connected to a network -- requires an even more complex back end. No doubt, the cost and complexity of VDI has been a challenge that has slowed down or stopped more companies when it comes to diving into the VDI pool.

Desktop as a Service to the rescue

One particularly interesting development that promises to change things is cloud-based VDI, also known as Desktop as a Service (DaaS). DaaS makes it possible to move virtual desktops to the cloud, along with other cloud-based applications and infrastructure. DaaS offers all of the advantages of VDI without the frustrations involved in procuring, deploying and managing virtual desktops in-house.

Soon, DaaS companies will refine their business models and prices will come down as the service becomes more mainstream. As VDI technology matures and DaaS becomes widely available, more and more companies should move to VDI. We see the day coming when most enterprise companies will have some or all of their user desktops running on VDI, most likely in a cloud-based form.

Do you think Desktop as a Service will drive more people to adopt virtual desktops?
VDI rental could be as the mobile bundled program and IPTV bundled program operated by the data landline operators for SMB customers
LOL.....our data does not leave our care
Infrastructure is Scalable and needs replacing less frequently than Workstations
One of the biggest blockers for DaaS is Mircrosoft and their inflexible licensing. That aside just because you you offsite things doesn't mean you should. VDI onsite can benefit from multiple Gbps connections between the endpoints and the backend for the majority of the access with the minority connecting over WAN. Add to that the fact that onsite IT will still be required for applications such as high end processing or external hardware compatibility (think PC driving machines such as robots or science equipment) and now you start asking where shall I put the data? If it's offsite the onsite users get a poorer service if onsite the offsite desktops get a poorer service. I think it might work for small businesses with a mobile workforce but very difficult to imagine how it would work for above 100 users say. I have deployed a 100 user DaaS solution for a University and worked very well but it was difficult to make it commercially viable.
It's a good way to test this solution
More control over machines in the internet
We agree only partially that DaaS can act as a catalyst to boost VDI adoption rates. We don’t think DaaS is a holistic answer to resolve VDI woes. DaaS only creates virtual desktops but does not guarantee SLAs on application delivery to the end-user. So IT teams can get some benefits of virtualization but are their end-users better of? answer maybe yes or no.

This is where Application Delivery As-A-Service (ADaaS) comes in. ADaaS (link to - http://www.anuntatech.com/blog/?p=261#more-261 ) on puts application delivery at the centre of a VDI implementation and instead of merely focusing on device uptimes, focuses on application performance at end-point. By profiling the user base to ascertain their usage pattern and categorizing users by the kind of VM they need, ADaaS manages the entire application delivery chain from server to screen, providing a predictable and deterministic way of delivering applications thereby maximising end-user performance.

So, while opting a DaaS solution is great, knowing how to enhance the end-user experience is more important. ADaaS is a next generation solution that provides a keen alignment of IT with business so while it may seem much more premium to DaaS, it is, in our opinion, what enterprises should be concerned with.

If you look at the long run Business dynamics. people require DAAS.

CAPEX is one of the major factor which will help DaaS to grow..
network,security etc.
DaaS is simply a new way of hosting. What IT teams need is a way of ensuring delivery as well. What will drive virtual desktop adoption is a model like ADaas.
read a comment that says LOL...our data does not leave our care. Has the user not heard of private cloud? He/she can still get all the advantages of DaaS with ADaaS.
Ultimately it will increase numbers, but of course whether the benefit is realized by the business depends on a lot of other factors - for certain scenarios Daas works very well, for others it will need more time to mature. For SMB's without large, well trained technical staff, it will make Virtual desktops a real possibility
