The upcoming Citrix Project Delaware release of Citrix Presentation
Server, the AIE feature will be removed. AIE technology was introduced in
Presentation Server 4.0 and has been replaced by the Application Streaming
feature of Citrix Presentation Server 4.5.
Refresher on AIE:
With AIE, you can run any locally installed application
under isolation. You can also "profile" an application
installation using the command line tool aiesetup.exe. Notice that all of
this activity is server side and specifically, there is no client side aspect
of AIE. With Application Streaming by contrast, you must profile an
application to run it and execution can be either on the server or on the
client desktop system. Application Streaming also allows streamed
applications to be used when disconnected from the corporate network.
Most aspects of Application Streaming are a superset of AIE,
but in deleting AIE, the ability to isolate a locally installed application on
a Presentation Server will be "lost". This post shows how
to "get it back". It also shows how to implement AIE function
"client side".
Consider that AIE and Application Streaming share many
components. The disk filter driver that supports both is common code -
common binary! Other components have been replaced completely such
as the COM virtualization and registry hooking mechanism. I'll add that
this is generally to an improved solution. The technologies are
similar enough that an AIE environment can be simulated via Application
Streaming.
Customer example:
In a recent telephone conference call, I was presenting the
Three-Ps of Application Streaming. First, PROFILE using the Streaming
Profiler, second PUBLISH using the Access Management Console and third PLAY
using the Streaming Client. The customer was interested in Stream
to Desktop to allow some highly graphic and CPU intensive applications to
run on the desktop streamed - rather than be locally installed - allowing
publishing and maintenance via Citrix and Application Streaming. A 15
minute pitch - done. Customer is thrilled.
It is here that I figure out why they are thrilled.
Client side CPU and Graphics are great, but the real winner is that the app can
be managed centrally, updated everywhere with one update and, here's the
kicker, published via the Citrix Web Interface!
Their users use the web interface as their portal to launch
applications, period. They do not use the Start Menu, they do not use
desktop icons. This makes locally installed applications a headache
and Application Streaming solves that problem - for the applications that they
move to streaming. The rest of the locally installed applications are
still a headache.
