8th Virtualization Expo New York My role allows me to speak with many different people (customers, technologists, coworkers, administrators, etc). I've been able to see presentations comparing the different desktop virtualization solutions out there.  One of the problems I see is that many of the solutions only focus on one aspect of desktop virtualization, and that is the VDI model. VDI is only one aspect of the entire desktop virtualization solution.  This is a concept that many fail to comprehend. For example, I attended Gartner ITExpo and was amazed at how many people I talked to only thought about the VDI scenario (you know VDI, allowing you to have a remote virtual desktop running on a hypervisor in the data center).  When I talked to people about the other options, I could see their eyes light up. If you are reading this and only know about the VDI version, the... (more)

Cloud Computing Is a Big Whiteboard

Daniel Feller's Blog Am I the only one who has trouble understanding Cloud Computing? Is Instant Messenger considered cloud computing? Is my company's enterprise deployment of XenApp on XenServer considered Cloud Computing? Is the iTunes store considered Cloud Computing? Why is Cloud Computing so hard to figure out? Well, look at it from a different perspective. Have you ever laid down on the grass and looked at the sky and tried to figure out what a cloud looked like? You might think one cloud looks like a puppy and another looks like an airplane while someone else thinks your pu... (more)

Windows 7 Migration Is Here

The migration to the new operating system was a challenge. We had a mass of people going to each user's desktop to copy their data and  rebuild the operating system.  We thought we planned appropriately but ran into all sorts of issues like: We didn't have the correct hardware drivers for some of the computers, which required searching the Internet and oftentimes using try and error until we found the right driver.  There were too  many occasions where we were unable to find a driver for the new operating system.  We just hoped the user wouldn't notice. We sometimes found out th... (more)

Virtual Desktops in the School

Schools typically have limited funds to take on massive IT projects. In fact, many of the desktops are over 5 years old, with significant numbers of desktops reaching 10 years old. So how does a school expect to maintain aging hardware. How does a school plan to provide students with newer applications? These are some of the challenges with one particular environment: the ABC School District. This particular school district consists of 50 school campuses that supports 70,000 users.  Due to limited funding, the technology infrastructure is aging quickly.  Thanks to a voter approv...

Improper Resource Allocation

If you ask me what type of desktop I need, I'm going to give you specs for the most powerful, uber-cool desktop on the market.  But if you look to see what desktop resources I need, you will see that the specs are quite a bit lower: 1 core and maybe 2 GB of RAM. In fact, when I look at my resource consumption, I get close to 2 GB of RAM by the end of the day due to the number of applications I have running, memory leaks in some of my applications, and applications not freeing up memory when closed. Like me, many users only consume a fraction of their total potential desktop comp... (more)
