Understanding Virtualized Videoconferencing

Philipp Karcher
Server virtualization has been and continues to be a top IT priority for good reasons like improving infrastructure manageability, lowering TCO, and improving business continuity and disaster recovery capabilities. In IT's quest to virtualize more workloads, however, videoconferencing has remained on its own island of specialized hardware due to its reliance on transcoding DSPs (digital signal processors), an incredibly compute intensive type of work. Transcoding is necessary for interoperability between unlike videoconferencing systems, and the performance of that specialized hardware has been difficult to match with software running on standard servers. 
 
That is, unless you turn to a model that doesn't use transcoding. Enter Vidyo, whose virtual edition infrastructure delivers comparable performance to its physical appliances since it doesn't have to transcode calls between Vidyo endpoints. Desktop videoconferencing solutions for the most part are available in virtualized models. However, transcoding based videoconferencing is also becoming available virtualized, with LifeSize offering its platform in this model. In the cloud, Blue Jeans -- the poster child for videoconferencing as a service -- has a virtualized platform based on transcoding that also provides a high quality experience. It will be interesting to see how the performance of virtualized transcoding workloads compares to traditional infrastructure.
 
Innovation in videoconferencing today is about making this historically cost prohibitive technology cheaper and easier to deploy. Server virtualization is key to that goal. In conversations with end user companies considering their videoconferencing strategy, virtualization is something they express interest in and would consider the next time they refresh their technology. Here's what vendors in the upcoming Forrester Wave on desktop videoconferencing are doing with virtualization today:

How Is Desktop Videoconferencing Being Used In Your Business?

TJ Keitt

For those of us who following the collaboration software space, video in business has been a hot topic: We have seen year-over-year growth in videoconferencing implementations, a majority of businesses are interested in or implementing video streaming technology, and the emergence of vendors offering "YouTube for the enterprise" services that allow information workers to create and share business-related videos. What's driving all of this interest in video? From a business leader perspective, you could argue that video enables more efficient and effective communication and collaboration for increasingly distributed workforces. For rank-and-file information workers, exposure to consumer services like Skype, Facetime (the video chat capability on Apple's iPhone) and YouTube have made them comfortable with the idea of video communications, which brings me to the subject of this blog post: how is desktop videoconferencing -- communications via a video unit on the desk like a Webcam -- being adopted by businesspeople?  

In our most recent survey of information workers (those who use a computer to do their job), we find that while 29% of workers use videoconferencing technology, only 15% have access to desktop video technology. The bulk of those using this tool are not the rank-and-file, but the managers and executives who have historically been the users of videoconferencing services. Considering the increasing acceptance of this more personal form of video in the consumer realm, these light adoption numbers raise the question about how this technology can spread throughout businesses. I'm currently working on a report on this very topic and I'm interested in hearing from you. Has desktop videoconferencing found its way into your business? If so, who led the charge and what was the rationale? If not, what is hindering implementation and adoption?

Let's have a conversation about this.
