David Paoleschi sent me a quick blurb that XenApp 5 on Windows 2008 will no longer provide an option for Application Isolation Environments (AIE). Application streaming will be the preferred way to isolate applications on XenApp for Windows Server 2008 going forward.
Personally, I have never had the need to leverage the AIE in my XenApp builds so I really wouldn’t have even noticed. I also have the impression that the AIE in general was a misunderstood and rarely used feature in XenApp.
If you used Application Isolation Environments or had different experiences with AIE, let me know in the comments. I’m curious to know if my impression is correct.
