User layer: It is the layer where we found our users, and also it is the place where we have a receiver of citrix and endpoints. We can do everything through the end user, with the help of SSL citrix receiver units with netscaler that is in the next layer for this connection public signed certificate is required.

Access layer: This phase includes the components which are required by users for their data and applications management, gateway of netscaler is one of them that is required for security access designing. Users may use this secure connection to connect with the gateway of netscaler from the receiver of the citrix, while logged in storefront displays the apps and alpong with netscaler it interacts with HTTPS/HTTP.

Control layer: In this layer our apps are used to manage the solution of our XenApp, the given below are its components list.

• Studio: Studio is used to access our users and apps.
• Director: This component is used to review the process.
• License server: The entire products of the citrix utilize the server of central license for our licenses of citrix.
• Active directory: It works like a service of our microsoft directory.
• SQL database: There is a requirement of a database for XenDesktop, XenApps to keep the entire resources and settings.

Resource layer: It is the layer where we found all our resources for our users from the following

• Pooled desktops
• Dedicated desktops
• Applications 

We can also say our entire VDAs which interacts with delivery controllers in port 80, and also associated with netscaler on the same platform.

Hardware layer: The entire layers which we discussed require hardware that supports all layers, with this we can keep our hypervisor and also our physical servers.

Citrix NetScaler SDX

Citrix netscaler SDX is a kind of appliance of application delivery which is based on hardware for datacenters of the cloud and business, it assists the organization of various instances of netscaler with single hardware and it is used for multi-tenancy processes. The given below are the components of the citrix netscaler SDX.

• Xenserver: It works like a hypervisor
• Service VM: It offers services such as VPX modification, and works as interface management for SDX
• Netscaler VPX: It equipped on SDX to offer solution for multi tenant
• 3rd party VPXs: These VPXs may also be organized on SDX, those   VPXs  of 3rd party are like websense, palo alto and trend micro.

Load balancing of Citrix NetScaler

The load balancing of citrix netscaler is performed through 2 methods one of them is GUI and the other one is CLI, some select CLI instead of GUI as it provides more control of file system and operating system and also offers us the knowledge of scripting and tasks of automotive.
