Protection from antivirus. Are you wondering if you read that correctly?
Yes, it is correct. Odd isn't it? Anti-virus is there to protect us, but
we also need to be protected from antivirus. Antivirus solutions are
critical, even in a virtual desktop environment. Many people believe that
because a hosted VM-based virtual desktop image is created from a real-only
image that they are immune from virus. That is only partially true. When
you reboot, the virus goes away because the changes to the base image are
destroyed (including the virus), but what about that time period between
getting infected and the next reboot? Those few hours are dangerous.
If using hosted shared desktops or hosted VM-based VDI desktops, those
virtual desktops are located within the data center with other critical
systems. If a virus made it into the data center, the entire infrastructure... (more)

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)
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)
Do you ever wonder how much bandwidth you need to do a desktop virtualization
implementation? Regardless of the flavor of virtual desktop being implemented
(hosted shared, hosted VM-based VDI, local streamed, etc), the network plays
a critical role. That should not be surprising (if it is, we need to have an
even bigger discussion). If you don’t plan your network bandwidth
appropriately, you will have unhappy users, who will make you unhappy, which
is one of the 10 biggest mistakes to avoid when doing virtual desktops
As we would expect, the user experience degrades as the latency... (more)
Do you believe these statements?
In order for me to see any value in doing desktop virtualization, I have to
move all of my users to a hosted VDI model. I don’t need a VDI type desktop
as I can simply use hosted shared with XenApp.
I’ve had many discussions with people who have these, as well as plenty of
other statements about desktop virtualization. This leads me to believe that
many are seeing desktop virtualization as a big bang effect (great TV show by
the way), that is in an all or nothing approach. This couldn’t be further
from reality.
Many of the organizations doing desk... (more)
