iForum session Desktop Virtualization – is it hype?
Delivered by Sumit Dhawan – Senior Director – Desktop Virtualization Group
Key points:
- Current desktop process is slow, complex, insecure and costly to maintain
- Task workers 30%, Office workers 55%, Mobile workers 15%
- Office workers seems to me to be way to broad a classification
- Office workers are characterised as needing a “personalized” environment
- Task workers
- Standard work environment
- Fast startup/low cost
- Data security
- Compliance and control
- XenApp is a great solution for these users
- Seems to me that this description above does apply to lots of office workers as well, even consumerized use cases. In my case for example for enterprise applications – I would be happy with the above, so long as my client was a non locked down laptop
- Mobile workers
- Frequent travel and offline work
- Unmanaged or lightly managed laptop
- XenApp is a great solution for these users
- Office workers
- Mainly work in the office
- Inter office roaming
- Office day extenders
- Assumption that XenDesktop is the solution for these users
- Citrix believes XenApp is the way to deliver the apps to these users
- My concern over this positioning is that it also kind of assumes a person works at a desk, rather than someone else’s desk (shoulder to shoulder) or in a conference room or some other collaborative space
- 1st generation VDI – which maps to my maturity level 1 – has mainly been for customers who wanted to solve mainly security related issues, at least these were the projects that succeeded
- Lots of talk about the ability for users to personalise, for example installing Active X controls. But no explanation as to where these personalisations get persisted if you are using provisioning server!
- Given this lack of a persistence solution, its unclear to me how XenDesktop differs from XenApp Presentation Virtualization
- Discussion of the slow degradation of windows desktops over time. Its not clear what causes this, however does it automatically follow that the same issues won’t occur when a PC is assembled every day from components, perhaps even worse if the components are virtualized (ie multiple copies of dependant components). However using XenApp published applications would be cleaner.
- However if XenApp published applications are being used how does a user add their own apps or add active x controls, or outlook add-ins etc.
- Repeated the benefits of using XenApp published apps, ie you can get up to twice as many XenDesktop users per server.
- Customer example
- Collier County public school
- 10,000 students, 1000+ staff, about 9,000 remote students
- Early adopter of desktop virtualization
- A customer that was caught in the “hype cycle”
- Deployed maturity level 1, didn’t get beyond the pilot
- Rolling out to about 50% of users
- Key message – use cases are key!!
- Costs
- Will this cut costs?
- For procurement costs Citrix believe PC is $1100 VDI is $1400, but by extending the life of the PC this cost increase will be reduced
- Lots of other cost discussion didn’t get covered, although they believe that TCO saving is 40%
