Understanding Virtualized Videoconferencing

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:
