Big news from BriForum 2013 London, which kicks off today! It’s been a little over a year since Gabe, Jack, and I published the first edition of our book, The VDI Delusion. While we're incredibly proud of that book, in hindsight we're not sure if we picked the best title. Calling it The VDI Delusion scared many people away as they thought it was a book about VDI haters and that we were anti-VDI. (And with a title like that, who could blame them?)

Of course VDI had been talked up by so many people over the years as being the “ultimate” corporate solution or the “future of the desktop,” so we felt that we had to have a strong title that would put VDI in its place, and The VDI Delusion certainly achieved that goal.
But if you read the whole book, you’d see that we only spent a small portion of it talking about the “delusion” part of VDI with the majority exploring how plan, design, and be successful with VDI. (In fact we could have just as easily called the book, How to Plan, Design, and Be Successful with VDI, and it would have been accurate. We’d probably have sold a few more copies too!)
So today we're announcing the publication of our second, gentler-titled, edition of last years’ VDI Delusion. There are two main changes we made.
First is the simple stuff. We’ve gone through the entire book and updated and refreshed it for 2013. We’ve added, changed, and deleted company and product names as our industry has evolved. We’ve made sure that everything we wrote aligns with our current “world view” of VDI.
The second change is more substantial. Since the first edition of this book was published last year, there have been two major technological innovations that have changed the game for a lot of VDI deployments.
The first is around storage. We always argued that VDI had to be about persistent “1-to-1” disk images, but doing so with traditional server storage was prohibitively expensive. This is why most VDI deployments have focused on non-persistent “shared” images, and why VDI adoption remained marginal. But now there are several vendors offering block-level, single-instance primary storage which means you can build a VDI environment for hundreds of users where each user has his or her completely unique disk image—all for a price that just last year could only buy a shared image system!
The second major breakthrough of the past year has been in the area of graphics performance, specifically the fact that multiple vendors now have plug-in cards for your remote VDI servers that can offload the processing, encoding, and compression of the remote protocol display streams. Adding one of these cards to a server means that you can dedicate all that processing power to the graphics experience without negatively affecting the user experience by taxing the existing CPUs.
These improvements in storage and graphics capabilities mean that VDI is now applicable in far more situations than it was before. This sentiment is corroborated by the number of large (more than 10,000 seat) deployments we’ve seen kick off over the past year.
To that end, we’ve substantially ripped apart and re-written the parts of The VDI Delusion that cover storage and the user experience around graphics performance. We’ve also expanded on our cost model conversation, added more content around networking and bandwidth requirements, and updated our future chapter to include the latest trends in web apps like Office 365. Taken together, we’ve decided to retitle the book, The New VDI Reality.
To get this book, we've also partnered with two sponsors: Atlantis Computing and Devon IT. Similar to the deals we did with Quest Software and Stoneware for the first book, they're sponsoring a free download of the PDF or Kindle edition. (If you're attending BriForum 2013 Chicago, they'll be passing out paperback versions there.) As in the past, neither Atlantis nor Devon IT wrote the book or influenced the content, rather it's our book with an extra chapter written at the end by them. So instead of paying $9.99 on Amazon for it, you can get it for free by logging into the linked page with your TechTarget account information. Enjoy!
