That Constellation thing sound to me more like balancing resources based on
your historical usage and application needs. So if you are an executive and
only use Outlook, you would be given Outlook from the least loaded resource,
if you are a worker using a desktop with many specific applications, you
would go to the best server for that. Another part they mentioned was
pre-launching apps based on who you are as well.
I think what Jim was saying was more about having your profile follow you
across machines with the exact state of all your applications and data
intact. I think a good name for it might be "Smooth Roaming Across Hosts".
You start a session on one machine or host and as you work it can be moved
intelligently across systems as needed for location, load, maintanence, etc.
A really exciting application would be a DR protocol with NO interruption of
service!!

Citrix is developing autonomic (sp?) load balancing which will do something
like this. They discussed it at iforum last year as part of constellation.
It will be able to watch how people work and use their sessions and then
determine how to load users across servers based on their usage history.

Remember the Virtual Workplace video Citrix showed at Iforum about 4 or 5
years ago? It was very Star Trekkish with a guy walking around with a little
portable computer holding a tele/video conference with people around the
world. He went from his office, to his car and then to his home where he
plugged into a cradle and brought the conference up on his giant plasma TV.
They connected people from all over the world. When the channel got staticy
and dropped and then came back up, he went Oh never mind we just switched
over to a new server.
Ok that was Citrix's vision of access back then. Any where, any place, and
any device. Fast forward to 2006. The CPS 4 package has much of this
functionality.. session reliability for example and application isolation so
apps don't step on each other. Conferencing built in and more.
Now stay with me here and I will take you on a visionary dream of mine and
eureka moment I had last evening in my sleep. (and yeah this happens all the
time)
Maybe we are approaching this whole virtualization thing backwards. Instead
of virtualizing servers and desktops I think we should be virtualizing user
profile sessions.
Here is my dream. You know how VMWare has that Vmotion stuff where you can
move a machine over from one physical server to another and not miss a beat?
That is pretty awesome stuff. I started thinking (while I was dreaming of
course0 why can't someone come up with a way to have multiple identical
servers with the same apps loaded on them and an admin tool that can take a
users entire logon session profile(everything they are doing) and move JUST
THE SESSION with the profile over to another machine. And then I took it a
step further. It could be automated with a tool to monitor users sessions
and move ones over that are stressing the CPU over to a less used machine.
So instead of moving a whole server or machine over just move the user over.
This is sort of what happened in the virtual workplace video.
I'm asking how hard can this be to do? Put the entire logon into a "virtual
session profile"..everything the user is doing. If the users session slows
down they get a flag that pops up that Asks if they would like to be moved
to a less busy server, if they say yes, it saves their session state, tells
the user to hang on a sec while it moves the session profile over to a new
server and then restores and restarts the session on the new server. A step
further...give the user the option to save their session logon state..apps
open etc into a "virtual session profile" so that the could connect back in
days, weeks or even months later exactly where they left off. (and it
wouldn't matter which machine they connect to) With programs like
softricity to hold the basic backend app information something like this
should be doable. This is not the same thing as virtual desktops...I want
virtual SESSION profiles not Desktops!
Such a virtualization method would be way more useful than virtual machines
because you could do things like create a virtual profile with settings that
would not be changed and use it across your organization, you could then
have a flex type of setup that saved session settings and personal files in
another home storage folder if necessary.
The benefits being you never have to reboot a server with users on it, you
can have way more users on a real server than you can on a virtual server
and you would have much more control over users sessions as you could set up
a system to monitor only the ones you want. ...ie.. always make sure that
the Directors virtual profile is sent to the least busy server. I know some
of this stuff exists today but this is the panacea I want. Think it will
ever happen? I do.
