VDI, ok ? What’s next ? 58 Comments

This blog is a follow up to the discussion we had in Vienna during the Geek Speak session at E2E event. I had to leave to catch my flight back to France but this discussion was very interesting and I though about it during all my travel time... I'm still on it writing this blog VDI, Desktops... Shared, remote, dedicated, pooled and/or virtual VDI gives the possibility to deliver desktops to everyone, everywhere. Let's say it, in most of the company, users still needs a desktop, a Microsoft desktop; why's that ? Just because they are used to access a Microsoft Windows desktop at home and during the last 20 years we didn't deliver application using another way.

The amount of memory we tried to save by not publishing a desktop was quiet a lot and as we had to give a desktop back, we had to calcul again all the memory consume per user for a desktop and add more servers according to our results. As you can notice in the graph above, the difference between a seamless published Excel 2010 and a desktop (XenApp 6.5 with Excel 2010) is double. As we needed to publish desktop instead of only using published application, we had…
