Riverbed Technical Leader Steve Riley Q&A on Desktop Virtualization

Posted by riverbedtest on October 18, 2011

For this week's Federal IT Q&A with Steve Riley, we examine the considerations for agencies looking to deploy desktop virtualization, the associated considerations, the drivers, user behaviors, applications, as well as how Riverbed solutions play a critical role in ensuring the best possible user experience. 

To kick things off, Steve breaks it down about what are some of the drivers for VDI. Simply put, the consumerization of IT is high on the list. An agency can allow agents to bring in their own gear, or purchase — with a budget — gear, and then provide and manage a virtual desktop with applications securely. From an IT and budgetary perspective, desktop virtualization allows agencies to not have to purchase devices, manage and refresh them.

Virtual desktop is also truly enabling the dual use personal-professional device. And, as you may expect, iPads and Android-based tablets are the devices of choice. But, the beauty of VDI is it is device independent.

So, what is the Riverbed play? How is Riverbed accelerating virtual desktop infrastructure (VDI)? Earlier this year, we announced continued and enhanced support for Citrix XenDesktop. At around the same time, we announced an optimization solution for Microsoft RemoteFX. And, at VMworld in the summer, we announced an upcoming partnership with Teradici, the innovator of the PC-over-IP protocol. Clearly a lot of developments around VDI with more to come.  

If you have been keeping count, then you'll know that we're approaching the end of the Federal IT Q&A series with Riverbed technical leader Steve Riley. Next week, tune in for a recap and finale discussion on how everything we discussed (data center consolidation, cloud computing, data protection, mobility and teleworking, and desktop virtualization) is tied together. 

But for now, watch the below video Q&A with Steve.

The Challenges with Mobility and Virtual Desktop Infrastructure (VDI)

Posted by riverbedtest on August 23, 2011

As a commuter heading into San Francisco on BART for the past several years,  I feel as though I have actually witnessed a revolution. 

Just a few years ago, the common commuter either slept, read (books, newspapers, magazines), or stared in the distance.  Occasionally someone might take or make a call, or possibly send a text or two (I loved my nokia 8210, so small!).  

Today, however, the most common pose is a near constant stare at our smart phones or connected device. Stare

I’m as guilty as the next person, pounding away updates on my Blackberry.  But the behavioral change is fascinating to me. Will it always  be like this?  Is this just a phase or are we forever committing to our screens?

Sidestepping the discussion about whether or not you think smartphones actually make us dumb, the proliferation of devices has got me thinking about the impact these devices have on IT. 

The challenge of mobile devices was particularly evident at an event I attended a few weeks ago, it was a customer advisory council meeting for a very successful regional value added reseller (VAR) in the Southeast.  The company had assembled 15 of their top customers to discuss best practices and new technologies.

By a show of hands, the greatest challenge the group faced was the explosion of end user devices and the impact the devices were having on corporate networks and on IT support.  One attendee discussed how their organization had gone so far to embrace end user choice that their company actually issues a hardware/device stipend to all new employees rather than supplying a laptop or desktop. The end user could buy the laptop, phone or pad of their choice, while IT focused on providing support and making sure their networks could handle surging amounts of traffic.

All this lead to a very lengthy discussion about Virtual Desktop Infrastructure (VDI) – (you can find some very honest and comprehensive discussions about VDI here).  VDI is a topic near and dear to Riverbed customers since at the core of the VDI concept is the explicit separation of end users from their data. And as we’ve learned from client-server applications that run over wide area networks, any time you separate end users from their data, especially over great distances, performance can really suffer, and WAN optimization technology is required to deliver the level of performance users demand.

Based on some partner and customer research I conducted earlier this year, I found that today’s most successful VDI deployments take place on local area networks (LAN), often deployed in a single facility or campus.  Education, Government agencies, and various types of financial service companies are particularly attracted to VDI’s promise of controlled, single instance data.  And while early desktop virtualization pitches promoted the cost benefits of VDI, many studies have since shown the cost benefits are minimal.  The real primary attraction of VDI is the age-old IT attraction of centralized control.

However, the challenge of VDI is most evident is over wide area networks (WAN).  If you’ve ever been frustrated by a pause in sending an e-mail or opening an application in a traditional corporate office, try sitting across a WAN from your data on a dumb terminal when you begin to experience slow or inconsistent K..EY..S.T…ROKE..S, forget it, it’s the worst. VDI over the WAN is a real challenge, which is why Riverbed is spending so much time and energy on the subject.  Today, we already optimize the Citrix ICA protocol and we help our customers optimize VMware view deployments as well using RDP optimization. 

During his keynote at Citrix Synergy in May, Citrix CEO Mark Templeton discussed a future where users would enjoy device and network independence.  I think we’re still a ways off from that, but I’m certain Riverbed will help the world get there.  Citrix

And for all my fellow BART commuters staring at your phones, just be thankful there are companies like Riverbed hard at work optimizing your corporate and public networks so you don’t miss a post, tweet, blog, text, request e-mail, video….

Did you know Worldwide smart phone shipments increased 87% in the last 12 months
