Provisioning Services provides desktops to be provisioned and re-provisioned in real time, from a single shared disk image. It is a characteristic feature of XenDesktop, applying NetBoot to virtual machines while simplifying large-scale deployment and master image management.
Since the operation of a virtual desktop is highly dependent on the network, the performance quality of that network becomes very important. Citrix uses HDX as a generic term to refer to functions that, through the proprietary protocol ICA for screen transfers, optimize the handling of peripheral equipment and performance in transmitting content such as audio or video.
With VDI, selecting the location of the virtual machine that the user will access also becomes important. While XenDesktop is software designed to implement virtual desktops, XenApp is software designed for the virtualization of applications. Although, by deploying the entire desktop screen, you can use this similarly to desktop virtualization. The main difference is how the two are configured. With SBC, a single hardware instance can be shared with multiple users, thus enabling higher resource efficiency compared to VDI.
Moreover, since a stand-alone application can be transmitted, in practice there is a lot that can be done with application virtualization. With application virtualization, users can access these same applications regardless of the type of terminal or OS they are using.
Unlike in desktop virtualization, where the application can be accessed once you have logged in through another desktop, with application virtualization you can connect to and use individual applications, thus making user operations much simpler.
In other words, the difference between XenDesktop and XenApp lies in whether the object of virtualization is a desktop or an application. Rather than being a matter of which solution is better, it is more important to select the solution that best fits a particular goal or determine what can be done with a combination of these services. Since the features of both XenDesktop and XenApp are managed with the same architecture, it is possible to implement both solutions and utilize them under a single management system.
IT consultants are like a box of chocolates - you never know what you're gonna get. XenApp is the old Citrix Presentation server. The product on which RDP is based. It isn't virtualization at all, just traditional remote access. If I want to watch a tutorial on one of these products which one should I choose? What business need are you trying to meet?
All three products have important places in business, but they aren't necessarily similar. So we'd need to know what you are trying to do before we could recommend one. XenDesktop is a VDI solution. It is related to virtualization but it itself doesn't do virtualization. What is XenDesktop? What is XenClient? I just want to learn. I've seen that Citrix is needed to work as IT consultant in many companies.
If you've got the spare machines citrix offers evaluation versions of all three products, XenServer, XenDesktop and XenApp. The next area that differentiates the two is supported host operating systems. Without a doubt, the Achilles heel of VMware vSphere is the number of host operating systems supported by the program. On this front, the Citrix XenServer vs. Both these software packages support a variety of technical support media such as forums, instructional videos, online self-service, knowledge base, system upgrades, telephone, and white papers.
Now that you know more about both products, you can determine which best fits within your career path. Are you planning for a career in Cloud Computing?
