How Does Citrix Work?

How does Citrix work? Citrix is one of a few companies that offer comprehensive virtualization solutions to companies. Citrix products are built around virtualization technologies. Citrix software basically deploys applications and resources on a central server and publishes them to remote devices. Using the virtualization technology, Windows applications can be published to non-Window devices. Moreover, resources can be accessed from anywhere, anytime and from any device. Before choosing Citrix, it is important to know how Citrix works.

How does Citrix work? – Overview

Citrix software virtualizes Windows applications, desktops and resources to publish them to remote users. Citrix Virtual Apps (formerly Citrix XenApp) is a virtual application delivery tool that isolates applications from the underlying OS and from other applications to improve its performance and compatibility. These applications are streamed from a centralized location into an isolated environment where they are executed on target devices. The application configuration, settings and files are copied to the client device.

How Does Citrix Work?When you use session virtualization, applications are delivered from hosting servers in the datacenter using application streaming. The user is then connected to the server to which the application is delivered. The application gets executed on the server and the server power is leveraged. While the server receives mouse clicks and keyboard strokes, it sends screen updates to the end-user device. With XenApp and session virtualization, Citrix enables Windows, MAC, iOS and Android devices to run Windows applications from Microsoft RDS. On the other hand, Citrix Virtual Apps and Desktop (formerly Citrix XenDesktop) is able to deliver full VDI desktops to any remote client device. Using HDX technology, it delivers a graphical experience to end-user systems. When you understand how does Citrix work, you can choose between session virtualization and VDI deployments.

There are multiple components involved in a Citrix virtualization infrastructure setup. For instance, Citrix Receiver is a client-software that provides access to XenApp/Citrix Virtual Apps (formerly Citrix XenApp) resources from any device. NetScaler provides load balancing, performs server offloading and makes applications run 5 times faster. StoreFront authenticates users to sites that host resources and provides self-service access to applications and desktops. Studio is a management console that lets you monitor and manage the entire infrastructure. Director is a web-based IT support tool. To publish applications and desktops through Citrix Virtual Apps (formerly Citrix XenApp), you have to configure all these components. Moreover, there are three XenApp editions that come with different features and pricing structures. You have to check out features offered by each edition. While it requires lot of time and effort to choose an edition, once you start to setup, the complexity in configuring multiple components and managing them is a challenge. Adding to this headache is the frequent name changes to Citrix products. Moreover, Citrix products are highly expensive. Not only should you understand how does Citrix work, but you should also check the pricing structure.
