Citrix XenApp is a licensed software product of Citrix Company which is a solution for application virtualization. This product is the result of the idea of accessing software through the network and internet. This is done through the ICA protocol and Citrix allows remote users to access the software in this way.
If we want to describe the operation of Citrix in a simple way, we must say that its features are very similar to the Terminal Service (Remote Desktop) of Windows, with the difference that instead of accessing the Windows desktop, Citrix only provides the software itself to the user.
ICA is an optimized RDP protocol that enables remote users to access software regardless of operating system and using a low bandwidth. Apart from accessing the software through a low bandwidth (at least 56 Kbps), another important feature of Citrix is that it provides access to Windows software in non-Windows operating systems such as Linux.

Reducing hardware costs with application virtualization solutions
A small example of reducing hardware costs using the Citrix application virtualization solution can be the provision of graphic software that requires a lot of resources for processing.
For example, companies that use graphic applications such as AutoCAD software can use Citrix Application Virtualization solution instead of installing and implementing these softwares on expensive computers with the amount of CPU, RAM and Graphics. Cart above, transfer these software to the data center and install and run it on a strong server.
In this way, the applicant users can access these software from anywhere and at any time, in a completely secure platform. Software or desktops are located on virtual or physical infrastructure in the data center, and users can access these graphic software with any device, even using their tablets.
Among the most complete and effective virtualization solutions for 3D software, Citrix offers 3D Application. This solution also provides technologies to optimize the presentation of 3D software in low bandwidth networks.
Development of Windows Remote Desktop services
By adding key components to the Windows Remote Desktop Service (RDS), XenApp has created the best classic strategy for any type of access. XenApp along with RDS support the strategic needs of organizations for projects and growth. Just ask the more than 230,000 Citrix customers who can attest to the performance of XenApp with RDS.
Increasing security and intelligent property protection
Centralizing applications and information in the data center ensures that the virtual delivery and management of applications are secure by design. Encrypted connection, advanced access control and legal password management provide an additional layer of protection for company assets and funds.
50% reduction in the cost of users’ computers
XenApp reduces the cost of users’ computers by simplifying the operation and providing all Windows applications up to 50%. Centralizing the programs in the data center reduces costs and allows IT managers to prepare it for all users by installing and configuring an instance of a program instead of installing and configuring it on each user’s computer.
What is Citrix XenApp?
XenApp is essentially just a piece of software or a group of pieces of software in its most basic form. Before becoming XenApp, Presentation Server, MetaFrame, and WinFrame were the names used for it.
With XenApp, you can install applications on a server and then access those applications on a client without installing anything other than the Citrix client software. The server handles all processing. Only mouse movements, keystrokes, and screen refreshes are transmitted between the client and the server, and the same is true for the other way around. Independent Computing Architecture (ICA), a proprietary remote display protocol developed by Citrix, is used for this. For the most part, users perceive the application as if it were running locally on their client operating system.
Additionally, it is possible to publish the server desktop, providing users with access to the server’s installed applications as well as the full Windows user interface. Hosted Shared Desktop is the term used for this.
Application virtualization, also referred to as application streaming, has been a feature of the last three XenApp releases. This took the place of the application isolation feature that was present in some earlier XenApp iterations. Without installing anything other than the Citrix Offline Plug-in, you can stream an application to a target Operating System by profiling it using the Citrix Streaming Profiler.
You have the choice of streaming the application to the client device or to a XenApp server when using application streaming. If you stream an application to a client device, it will run locally on that device and use local resources (CPU, memory, etc.); however, if you stream an application to a XenApp server, it will run on the XenApp server and be accessed over ICA just like a regular XenApp server-installed application.
Streamed software only requires a network connection for the first run or when the central package is updated because it is cached on the target operating system.
