Entity Templates

An entity template simplifies configuration by providing a set of configured defaults for a policy, service, action, or other configuration entity. After you create an entity template, it can be reused with specific instances of entities of the same type. For example, an entity template created for Load Balancing, can be used to create the same load balancing configuration on the same load balancer, or can be used on a different NetScaler or NetScalers to create the same load balancing configuration.

Entity Templates are most helpful when you have built your configuration for an entity such as load balancing and want to duplicate it across the organization's load balancers without having to re-type all of the configuration commands. In fact, the entity template manager, will allow you to prompt for certain configuration parameters to be input by the user, such as IP Address and port number, at the time of import, which might be specific to a certain locality.

Application Templates

The NetScaler includes the ability to create and manage application templates that provide the administrator a way to configure the NetScaler to handle application-specific traffic without directly configuring NetScaler entities. An application template is a reusable bundle of application's configuration information and can be exported after creation for use on other NetScalers. Also, these templates can be created once and then re-used across multiple NetScalers.

Application vs. Entity Templates

Entity Templates simplify configuration by providing a set of configured default for a specific configuration entity, such as load balancing, rewrite or content switching.

Application Templates simplify configuration by providing configuration details for all entities for an Application, such as Sharepoint, SAP, Oracle, or other web based applications. Application Templates are more comprehensive and contain configuration details for caching, compression, load balancing, ssl offload, rewrite, filtering, responder and application firewall. For one application you might have several policies in each of these categories that are saved into an Application Template.

Both Entity and Application Templates can be exported and imported for ease of use across different NetScalers. All of the configuration policies, including all expressions, pattern sets and policy labels are exported with the Entity or Application Template - once you define your policies, you don't have to define them again.

Not very long ago I published a series on how to become an Application Expert. Citrix NetScaler 9.0 makes it easier with AppExpert Templates. NetScaler AppExpert Templates - introduced in NetScaler 9.0 - provide an application-centric view of the NetScaler system's policy configurations. From a single place within the GUI (AppExpert -> Applications) NetScaler administrators can: 1) Configure the various AppExpert features the NetScaler is fronting, 2) View which NetScaler functional modules (e.g., compression, caching, application firewall) are optimized and active for a given application unit.

Additionally, AppExpert Templates allow you to drill down and see which individual NetScaler policies are active, and what policies are inactive but available, by application component and NetScaler module. From this same view, individual policies can be created, activated and deactivated.

AppExpert Templates can be downloaded, imported, modified and exported AppExpert Templates page of the Citrix Community Website. Administrators can download AppExpert Templates built by Citrix, Citrix Partners and members of the NetScaler community from the Citrix Community Website. These templates are easily imported into any NetScaler running NetScaler 9.0 or higher, jump starting the configuration and deployment process. Templates developed in-house can be easily exported and shared within your organization, or posted back to the Citrix Community Website for others to view and improve.
