Project VRC: Application Virtualization has major impact on VDI

Independent Research Project VRC: Phase IV describes pros and cons

Today PQR and Login Consultants released Phase IV of Project ‘Virtual Reality Check’ (VRC). The white paper describes the impact and best practices of application virtualization on a Virtual Desktop Infrastructure (VDI).

The R&D project ‘Virtual Reality Check’ (VRC) started in early 2009 by PQR and Login Consultants. The objective of this project is to independently analyze the developments in the application and desktop virtualization market and present the results. Independent test scenarios - now more than 1000 – lay at the basis of the VRC projects.

Ruben Spruijt, PQR Technology Officer, Sven Huisman, Consultant at PQR and Jeroen van de Kamp, CTO at Login Consultants explain the impact of application virtualization on VDI in the whitepaper ‘Project VRC Phase IV’. Central focus is the consequences for the scalability of the infrastructure. The tests compared Citrix Application Streaming, Microsoft App-V and VMware Thin App in different configurations.

The benefits of Application Virtualization are clear: isolation, virtualization and on-demand deliverance (through streaming) of applications to provide greater dynamics and flexibility. Obviously there are also drawbacks: not all applications can be virtualized, the interaction between virtualized applications can cause problems and the used techniques provide a heavier load on the available system resources.

Spruijt: "We have examined different scenarios for Application Virtualization. For instance, it is remarkable what the effect on performance of the VDI environment is and thus on the number of simultaneous users. Not well-thought-out virtualization can result in a decrease of up to 40%! VSImax scores and surveys from the I/O perspective show striking differences between the major players in the marketplace. We conclude that the on-demand streaming of applications has many advantages, although we emphasize there are implications for the scalability of the infrastructure! "

The performance of VDI environments in different configurations, including a worst case scenario, have been tested. Findings, conclusions and recommendations provide food for thought and discussion and are described in the pdf which can be downloaded on www.projectvrc.com as of today.

The benchmarking software used for Project VRC is Login VSI. Anyone interested in the results or in performing the scenarios themselves can do so by requesting a demo of Login VSI. The test environment and methodology used are also described in the free white paper.
