8th Virtualization Expo in New York on Ulitzer Have you experienced this before? You need an application to help you with a project. You ask your manager if you can purchase the software and you get approval.  You go out and buy the software and install it onto your desktop and away you go to do your job.  This is a common situation, one I've done myself on many occasions. These applications make up the non-IT delivered application set of every organization, and it is a massive list.  This happens over and over again in every organization and in every department. So when you hear organizations say they have 10,000 or 20,000 applications, they are likely not exaggerating.  Out of that massive list, only 500-1,000 of those applications are IT-managed.  This brings about the main challenge with desktop virtualization, how do you deal with the non-IT delivered applicati...

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)

Desktop Virtualization.... The Right Way (Part 2)

Virtualization Magazine on Ulitzer One of the questions you must ask yourself when designing a desktop virtualization solution is understanding the user patterns.  This has a direct impact on XenDesktop farm design and scalability with respects to boot up storms and logon storms. Let's take two different examples so you can get a better idea for what I'm talking about: Scenario 1: 9-5: In this scenario, all users logon in the morning and logoff in the evening.  There might be some sporadic users working after hours, but for the most part users stay within these working hours.  Thi...

Desktop Virtualization... The Right Way (Part 5)

The user discussion doesn't just end with an understanding of the topology. Desktop virtualization architecture will only get a users so far: access to a virtualized desktop. If the virtualized desktop does not provide the required experience in different scenarios, users will find ways of reverting back to their traditional model or find a way to make life very difficult for you, the architect of this less than stellar solution. Trying to get these users back is challenging as the bad perceptions must be changed and that takes time. Many of the missteps with regards to the user ... (more)

Desktop Virtualization: The Right Way (Part 6)

Virtualization Expo on Ulitzer We've followed all of the best practices, did a proper analysis and design and are ready to start moving users to their brand new virtual desktop. But not so fast. We need to make sure we have the proper plan in place or else we will end up with incorrect applications, confused users, or lost files. A migration plan must be put into place providing the following for the users. Personalization Synchronization: A user's traditional desktop has become polluted with numerous application installs, updates, and patches. Blindly transferring these settings... (more)
