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 puppy looks like Homer and the airplane looks like a TV. Trying to find shapes in the clouds is all based on your perception, just like if you try to get a definition of cloud computing from 5 different people, you will most likely get 5 different ideas. Of the many discussions I've had on th... (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.

Get Ready for Cloudbursting

Just about every customer I've ever talked with has a common challenge, "How do we plan for cyclical surges in user activity?"  Depending on your business area, this could be a critical area of planning. Take for example, the retail sector.  We just came out of the end-of-year holiday spending season where retail stores typically see more foot traffic  and Internet-based traffic.  The increase in web traffic is several multiples higher than during other times of years.  If these organizations don't plan the infrastructure appropriately, their sites will become unavailable and c...

Desktop Virtualization.... The Right Way (Part 1)

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 ... (more)
