XenApp Explained

On-demand application delivery with Citrix XenApp How application virtualization and session virtualization work Citrix XenApp is an on-demand application delivery solution that comprises application virtualization and session virtualization technologies. Understanding application virtualization Citrix application virtualization technology isolates applications from the underlying operating system and from other applications to increase compatibility and manageability. As a modern application delivery solution, XenApp virtualizes applications via integrated application streaming and isolation technology. This application virtualization technology enables applications to be streamed from a centralized location into an isolation environment on the target device where they will execute.

XenApp Information

General Info: Sharing resources from one physical box(like esx, xenserver, hyper v etc) is server virtualization. Publishing virtual machines created by xenserver, esx etc to end users is desktop virtualization. Xenconvert is used for converting physical machine to VM. Multiple OS boots from single VHD file using provisioning services(PVS). ICA and RDP Differences: 1. RDP works only under TCP/IP, while ICA works on many protocols. 2. RDP doesn’t permit applications to run in a browser, while works for ICA
