Citrix NetScaler provides Web application acceleration and advanced layer 4-7 traffic management, enabling enterprises to increase Web application performance by up to five times, improve application availability and reduce datacenter costs. NetScaler Enterprise Edition is available as a family of scalable, purpose-built appliances to optimize enterprise application delivery for multiple high-traffic internal applications, or to ensure high performance and availability of public-facing websites.

Citrix NetScaler is available in three software editions and four purpose built appliance platforms, providing flexibility in selecting application functionality and system scalability.

Accelerate Application Performance

Citrix NetScaler Enterprise Edition can increase application performance by up to five times. Citrix AppCompress improves end-user performance and reduces bandwidth consumption by compressing Web application data, regardless of whether it is encrypted or unencrypted, before it is sent to the client. The optional Citrix® AppCache speeds content delivery to users by providing fast, in-memory caching of both static and dynamically generated HTTP application content.

SSL Acceleration

NetScaler integrates hardware-based SSL acceleration to offload the compute-intensive processes of SSL connection setup and bulk encryption from Web servers. SSL acceleration reduces CPU utilization on servers, freeing server resources for other tasks. SSL acceleration is automatically enhanced by TCP optimizations and is fully integrated with the AppCompress and AppCache functionality.

Intelligent Loadbalancing and Content Switching

Citrix NetScaler provides the industry's most comprehensive layer 4-7 traffic management. Deployed in front of application servers, NetScaler delivers fine-grained direction of client requests to ensure optimal distribution of traffic. In addition to Layer 4 information (protocol and port number), traffic management policies for TCP applications can be based upon any application-layer content. Administrators can granularly segment application traffic based upon information contained within an HTTP request body or TCP payload, as well as L4-7 header information such as URL, application data type or cookie. Numerous load-balancing algorithms and extensive server health checks provide greater application availability by ensuring client requests are directed only to correctly behaving servers.

Reduced deployment and operating costs

Citrix NetScaler Enterprise Edition lowers application delivery costs by reducing the number of required servers and by optimizing usage of available network bandwidth. The intuitive AppExpert Visual Policy Builder enables application delivery policies to be created without the need for coding complex programs or scripts. In addition, NetScaler reduces operational expenses by consolidating multiple capabilities in a single solution. For managing multiple NetScaler appliances, the separately available NetScaler Command Center provides centralized administration of system configuration, event management, performance management and SSL certificate administration.

Command Center

Citrix NetScaler Command Center is a management and monitoring solution for the complete Citrix NetScaler line of application delivery products. It is a feature-rich software product providing device discovery and full FCAPS functionality – fault management, configuration management, auditing, performance and security. Command Center enables network administrators to easily manage large-scale Citrix NetScaler deployments from a single, unified console:
