XenApp admins are a creative group of people.   I used to be a XenApp admin and I remember having to do tons of things to an application to get it working correctly on XenApp (but back then it was called WinFrame and MetaFrame, not even MetaFrame XP).  Back in the day, applications were not built to execute on a multi-user system like XenApp.  In fact, many applications today, especially those home-grown applications, are problematic on XenApp.  This is where the creative XenApp admins come in. They developed numerous tweaks, configurations, hacks and custom solutions in order to get an application functioning properly. Of course this made the environment much more complex to build and maintain.
But just getting applications functioning on XenApp is just part of the problem. I remember hearing people ask about running different high-graphics or video applications on XenApp and thought, ARE YOU NUTS?  ICA was built to only send those screen changes down to your video display, but with video the entire screen is changing.  Talk about chaos. 
THAT WAS THEN. THIS IS NOW.  Things have changed for the better.  Application issues are more of a myth nowadays.  With new XenApp features, many of the application challenges that plagued XenApp environments are being eradicated.  But unfortunately, many of you have experienced application issues years ago and haven’t looked at those applications since.  So I’m asking that we spend an hour going through the XenApp features focused on application compatibility in an upcoming TechTalk session.
I plan to discuss the technologies that make application compatibility easier, which will also help simplify your XenApp architectures.  We will go through many of the challenges you all have experienced and talk about how these are now easily overcome.  So I encourage you to attend this TechTalk session called: Fact vs. Fiction – The Truth About Application Compatibility and XenApp.
Can’t wait to see you there on Wednesday, May 27, 2009 at 1PM eastern time.
