Citrix NetScaler
Web Application Delivery with the Highest Availability, Security and Performance
Citrix® NetScaler® web application delivery solutions are purpose built appliances that accelerate application performance up to five times, while simultaneously reducing datacenter costs and improving web application security. Platforms range from the entry level 7000 to the latest MPX-series appliances that provide an industry-leading 15 gigabits per second of throughput at both Layer 4 and Layer 7 with maximum simultaneous use of all functional modules. They provide visibility into the end-user application experience and comprehensive web application security in concert with advanced traffic management. NetScaler, a member of the Citrix Delivery Center product family, is an ideal network management solution for any enterprise seeking accelerated Web application performance, improved web application security and increased application availability.
Accelerated Application Performance
Citrix NetScaler accelerates web application performance by up to five times by leveraging multiple acceleration technologies and innovative TCP optimizations. Citrix® AppCompress™ and Citrix® AppCache® deliver highly efficient data compression and caching of static and dynamic content to speed application responses. NetScaler TCP optimizations offers network management solutions that overcome the issues caused by high latency and congested network links and are transparent to clients and servers. This is done by accelerating the application delivery of any enterprise or web-based application while requiring little or no configuration. Real-time and historical page-level monitoring of end-user performance experience is provided by Citrix EdgeSight® for NetScaler.
Comprehensive Web Application Security
NetScaler offers web application security from application-layer attacks, helping to prevent the theft and leakage of valuable corporate and customer data. Patented Citrix® Request Switching® enables NetScaler to proxy legitimate client requests and block illegitimate requests, and includes high-performance, built-in defenses against denial of service (DoS) attacks. Legitimate surges in application traffic that would otherwise overwhelm application servers are automatically handled with configurable Surge Protection and Priority Queuing features.
Increased Application Availability
To help ensure application availability, 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 cuts web application delivery costs by reducing the number of required servers and by optimizing usage of available network bandwidth. The latest NetScaler offering, the MPX-series, provides multiple 10GE ports and the power to run numerous functional modules with traffic throughput in excess of 10 gigabits, even at layer 7. This performance offers the ability to prevent unneccessary network segmentation and thereby reduces the number of switches and other elements needed. The result is further infrastructure cost savings. 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 ongoing operational expenses by consolidating multiple capabilities in a single solution. Included Citrix EasyCall functionality improves employee productivity and reduces telephone communication costs. 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.
Citrix NetScaler is available in three different software editions and six different appliance platforms, providing choice of application functionality and required system scalability.
