Setting Up NetScaler appliance for XenApp/XenDesktop

A NetScaler appliance can provide load balanced, secure remote access to your XenApp/XenDesktop applications. You can use the NetScaler appliance load balancing feature to distribute traffic across the XenApp/XenDesktop servers, and the NetScaler Gateway feature to provide secure remote access to the servers. NetScaler appliance can also accelerate and optimize the traffic flow and offer visibility features that are useful for XenApp/XenDesktop deployments.

The above figure shows the components involved in this deployment:

  • NetScaler Gateway.** Provides the URL for user access, and provides security by authenticating the users.

  • NetScaler appliance load balancing virtual server. Load balances the traffic for the Web Interface or StoreFront servers. You can also deploy a load balancing virtual server in front of the XenApp/XenDesktop servers to load balance key components such as XML Broker and Desktop Delivery Controller (DDC) server.

  • Web Interface or StoreFront or Web Interface on NetScaler appliance. Provides the interface through which you can access the applications.

    Note: Web Interface on NetScaler (WIonNS) is a customization of the Web Interface product, hosted on the NetScaler appliance.

  • XenApp/XenDesktop. Provides the applications that your users want to access.
