What is Citrix XenApp?
We may hear the name of Citrix XenApp often enough, but does everyone understand what this product is about? Let’s take a closer look at this solution, and on the XepApp-focused certification.
Formerly known as WinFrame Server, Citrix MetaFrame Server and Citrix Presentation Server, XenApp is an application virtualization solution that enables users to connect to their corporate applications from a wide range of computer systems and mobile devices. XenApp hosts applications on central servers and allows users to interact with them remotely or stream and deliver them to user devices for local execution. Citrix Xen App extends Microsoft Remote Desktop Session Host desktop sessions and applications to users through the Citrix HDX protocol. XenApp was originally built on top of the Windows Terminal Server platform (which was developed by Citrix in mid 90s).
Citrix XenApp and Remote Desktop Services enable organizations to centrally manage their Windows applications and computing resources in a secure data center, which is especially important for organizations whose operations involve the flow of sensitive data.
As a cross-platform solution, Citrix XenApp enables users to access these applications from anywhere, including non-Windows clients. Here’s how it works: XenApp sessions and applications can be accessed by client devices using a software client Citrix Receiver which is available for a variety of client form factors and operating systems.
HDX protocol provides smooth remote display capabilities, multimedia redirection, USB redirection, and a variety of other capabilities, depending on the client device.
Citrix XenApp direct competitors are Microsoft Terminal Services for Windows Server 2008, Quest Software vWorkspace, Systancia AppliDis Fusion, Spoon Server and Ericom Software WebConnect. Win4Lin Virtual Desktop Server provided similar functionality for serving Windows desktop sessions from Linux servers, while Sun’s application virtualization offering, the Oracle Secure Global Desktop, serves to provide a complete solution allowing for the delivery of both Windows and Unix applications on all major platforms.
