The Virtualization Practice

Performance Management for Desktop Virtualization (VDI) and Presentation Virtualization (SBC)

Ovum’s research found that desktop virtualization currently represents approximately 15% of the business PC market. However, this figure is dominated by the Presentation Virtualization model (12%), typically used in call datacenter-type environments, and has been for the last 10 years. If PV/terminal services are excluded, the next generation of solutions aimed at CIOs, from the likes of Citrix, Quest and VMware, hold less then 3% of the market, showing that many CIOs are holding back from taking the plunge.

ExtraHop has now made an important contribution to the question of how to measure applications performance across physical and virtual environments. Properly deployed ExtraHop can play a critical role in helping enterprises virtualize the 60% of the remaining applications that are “hard”, “performance critical”, and “business critical”. As vSphere 5.0 is right around the corner, the timing could not be better.

What is still missing here is any kind of an end-to-end view of infrastructure latency that is also real time, deterministic and comprehensive. The marrying of the SAN point of view with the IP network point of view is the obvious combination. The hard issue here will be the identification of the applications so that these view of infrastructure performance can be surfaced on a per application basis. In summary, we have a long way to go here, and this just might be why so many of those virtualization projects for business critical and performance critical applications are having so much trouble getting traction.
