Citrix NetScaler ADC Enterprise Edition

Citrix NetScaler Enterprise Edition 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 website.

Accelerated 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. In addition, Citrix NetScaler delivers multiple TCP optimizations to improve the performance of the network and server infrastructure. TCP connection multiplexing reduces thousands of short-lived client connections into a much smaller number of long-lived, persistent server connections. This and other TCP optimizations reduce server load, improving server performance and accelerating application response times. NetScaler TCP optimizations are transparent to clients and servers, accelerating the delivery of any enterprise or Web-based application while requiring little or no configuration.

Intelligent load balancing 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.

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. Citrix NetScaler Enterprise Edition is also available in a FIPS-compliant model providing secure key generation and storage.

Comprehensive application security

Patented Citrix Request Switching technology enables NetScaler Enterprise Edition to proxy legitimate client requests and block illegitimate requests. Without any performance penalty NetScaler Enterprise Edition defends against damaging denial-of-service (DoS) attacks. Content inspection capabilities enable Enterprise Edition to identify and block application-based attacks such as GET floods. Legitimate surges in application traffic that would otherwise overwhelm application servers are automatically handled with configurable Surge Protection and Priority Queuing features.

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.
As the complexity of network traffic and application deployments increases, NetScaler Enterprise Edition can be upgraded to NetScaler Platinum Edition, protecting investments in Citrix NetScaler solutions.
