The system virtualises applications and desktops, allowing them to be remotely accessed by users from any device, without the need to install software on each device separately.

Citrix Server makes it possible for organisations to make use of a centralised data and application repository, providing access to applications and corporate data in a highly secure, reliable and flexible manner. The solution enables IT professionals to manage resources remotely, delivering applications and desktops to end-users over a network in a highly efficient way.

The system comprises of several components, including the Citrix Virtual Apps and Desktops, Citrix Hypervisor (formerly XenServer), NetScaler, and XenApp. All these products are designed to work together and provide users access to applications and files over the internet, enterprise network and in some cases, mobile networks as well.

The Citrix Virtual Apps and Desktops solution is the core of the Citrix Server system, providing a platform for hosting applications, desktops and user profiles. The system virtualises desktops to deliver mobile and remote access to applications, allowing users to access their desktops from any device.
