Overview Of Citrix Systems

Overview Of Citrix Systems

                       Citrix Systems, Inc. (NASDAQ: CTXS) is a multinational corporation founded in 1989, that provides server and desktop virtualization, networking, software-as-a-service (SaaS), and cloud computing technologies, including Xen open source products.

Major Citrix Components
  1. Xenapp
  2. Xendesktop
  3. Xenserver
  4. Provisioning server
  5. Netscaler

             Citrix XenApp (formerly Citrix WinFrame Server, Citrix MetaFrame Server and Citrix Presentation Server) is a application virtualization product that allows users to connect to their corporate applications. XenApp can host applications on central servers and allow users to interact with them remotely or stream and deliver them to user devices for local execution.


          Desktop virtualization(sometimes called client virtualization), as a concept, separates a personal computer desktop environment from a physical machine using the client–server model of computing.
Virtual desktop infrastructure (VDI) is the practice of hosting a desktop operating system within a virtual machine (VM) running on a hosted, centralized or remote server.Xendesktop is the VDI software provided by citrix. It helps in the easy management and administration of Virtual desktops.


       A hypervisor, also called virtual machine manager (VMM), is one of many hardware virtualization techniques allowing multiple operating systems, termed guests, to run concurrently on a host computer.Xenserver is an open source from Xen aquired by citrix. XenServer is a server virtualization platform that offers near bare-metal virtualization performance for virtualized server and client operating systems. XenServer uses the Xen hypervisor to virtualize each server on which it is installed, enabling each to host multiple Virtual Machines simultaneously with guaranteed performance. XenServer allows you to combine multiple Xen-enabled servers into a powerful Resource Pool, using industry-standard shared storage architectures and leveraging resource clustering technology created by XenSource.

Provisioning Server
              One of the major head ache of IT is to manage the OS and applications updates and fixes in 1000s of desktops & Laptops.Provisioning Server takes a very different approach by fundamentally changing
the relationship between hardware and the software that runs on it. Using“Software Streaming Technology”, Provisioning Server enables organizations to reduce the number of systems that they manage, even as the number of computers continues to grow. This solution simultaneously provides the efficiencies of a
centrally managed solution with the benefits of distributed processing.
