The Zen of XenApp/XenDesktop


Citrix, like Cisco and VMware, is one of the main players in network virtualization. Its primary solutions in this realm - XenApp and XenDesktop - are designed like the rest of the company's tools to deliver a top-notch experience for remote workers. But unlike other Citrix products such as the videoconferencing platform GoToMeeting (which Citrix spun off into a separate business in 2015), both of these offerings are designed with IT admins, rather than end users, in mind.

What can XenApp and XenDesktop do? At their core, these two similar virtualization solutions enable secure remote access for employees on any device. This capability is particularly important given the expansion of the market for virtual desktop infrastructure as well as the accompanying surge in bring-your-own-device initiatives at organizations everywhere:

  • Technavio has estimated that the global VDI market would expand at an 11 percent compound annual growth rate between 2017 and 2021, as a growing number of enterprises seek unified centralized systems instead of disparate individual ones.
  • RnR Market Research has made an even more aggressive projection, predicting that VDI will see a CAGR greater than 27 percent between 2016 and 2020. BYOD could be a key driver here: A Tech Pro Research survey once revealed that nearly 75 percent of businesses were exploring BYOD for their employees.
  • The rise of as-a-service business models for software and infrastructure delivery has changed how a lot of companies manage their infrastructures. Instead of buying and implementing assets on their own, they are more open to having them delivered on-demand from the cloud.

In the case of XenApp and XenDesktop, a wide range of applications - not just desktops - can be delivered virtually. Let's explore some tips for getting the most out of these platforms:

1. Deliver Linux apps and desktops

Linux is a linchpin of server virtualization, with more than an 11 percent market share, according to a 2016 Spiceworks survey. It is also gaining ground as a desktop OS and could further expand its footprint this year. For these reasons, having convenient virtual access to Linux desktops and apps is more important than ever.

XenApp and XenDesktop can deliver these Linux services even to non-Linux devices. Moreover, administrators can manage both Linux and MIcrosoft Windows desktops from a single console, thus simplifying their workflows.

For example, XenApp/XenDesktop helps support the migration away from traditional PBX phone systems.


2. Support graphically intensive applications

CAD software has long been a staple of day-to-day work in manufacturing and design. However, installing the relevant applications can be a costly and time-consuming process, especially since the machines in question are high-end workstations.

Virtualizing these 3-D applications makes it much easier for end users to access them from any device type, desktop or mobile. The network optimization of XenApp and XenDesktop ensures that the user experience is consistent as well as representative of the powerful PCs that many workers are accustomed to.

3. Virtualize Skype for Business

Skype for Business, the successor to Microsoft Lync, is a popular solution for business telephony. It is the centerpiece of many unified communications implementations, not to mention a cost-effective and scalable upgrade from traditional PBX phone systems.

The XenApp/XenDesktop HDX RealTime Optimization Pack optimization pack for Skype for Business is the only such upgrade certified by Microsoft, which also helped develop it. It delivers a native-like Skype for Business experiences to PCs, Macs and Linux endpoints via virtual apps or desktops supported by centralized data center infrastructure. This setup provides the reliability of a local instance along with streamlined administration.

4. Run virtual desktops, even if you are offline

XenDesktop has a more advanced feature set than XenApp. One of its unique capabilities is the option to deliver virtual Windows desktops to PCs and Macs, even if they are offline. It accomplishes this feat through the Citrix DesktopPlayer.

DesktopPlayer works whether a machine is online, offline or somewhere in between due to an intermittent and unstable network connection. It includes many security features - such as timed lockouts and remote wipe mechanisms for administrators - to ensure the integrity of the software in question.

5. Simplify app management and migration

Included in XenApp and XenDesktop is Citrix AppDNA, a tool for easily discovering, automating and manage applications so that essential tasks such as initial virtualization and eventual migration are as simple as possible. Overall, AppDNA speeds up IT projects while reducing implementation costs.
