Citrix NetScaler Technology

Citrix NetScaler is a web application delivery solutions in the form of Appliances, which can accelerate application performance up to five times and continually reduce data center costs, and improve web application security. There are several appliances available, ranging from the basic level, series 7000 until the latest series, MPX, which can provide Throughput 15 gigabits per second in both the layer 4 and layer 7 with the maximum continuously use of all the functional module. Citrix Netscaler is one of the Citrix product delivery center that is ideal for network management for all companies that need acceleration in the performance of existing web applications, increasing security in web applications and increase the availability of the web application.

Citrix NetScaler accelerated the performance of web applications up to five times by empowering technology to optimize the TCP acceleration, with Citrix AppCompress and Citrix AppCache able efficiently to send data compression and stored the static and dynamic contents on temporary storage (caching) to accelerate the response from the web application. NetScaler TCP optimization benefits providing network management solutions to resolve the problems of high latency, congested network links and transparent to the user and the server and only requires a little configuration and sometimes without the actual configuration. To Real-Time Monitoring and see all the Historical Page-Level end-users is available on the Citrix EdgeSight for NetScaler

Citrix NetScaler provide security against attacks on the application layer, helping the prevention of the occurrence of theft and leakage of customer data and companies data that have high value. With the Citrix Request Switching, the Citrix have some ability such as open proxy for users who have authorization,

close proxy for users who do not have the authorization even when the high-performance, and built-in defenses against denial of service attack (DoS).

With configure the Surge Protection function and Priority Queuing, The surges on the application's traffic that inflict a web server application could be handled.

To assist the certainty of availability of applications, Citrix NetScaler provided a clear direction of the user needs to ensure optimal distribution of traffic. For additional information on the layer 4 - Protocol and Port Number, traffic management policies for TCP applications can all refer to the Application-Layer content. An administrator can perform traffic segmentation applications gradually to the information contained in the HTTP request body or TCP pay-load. Also in the header information L4-7 as the URL, type of data application or cookies. With the large number of algorithms for load-balancing and the ability to make health checks the server application availability by ensuring that high-needs (requests) the user is directed only at the appropriate behavior of the server.

Citrix NetScaler is able to reduce the cost of delivering web applications by reducing the number of servers needed, and optimize the use of network bandwidth available. The latest series of Citrix NetScaler, MPX provides multiple 10GE ports and power to run all the modules function with the traffic throughput of 10 gigabits even in the layer 7. This performance provides the ability to prevent the network segmentation is not necessary that can reduce the number of switches and other element, the result is a savings in the cost of infrastructure. With the AppExpert Visual Policy Builder making application delivery policies do not require coding or script again. In addition, the current NetScaler can reduce the cost of Operational with some ability to consolidate in one solution. Using the Citrix EasyCall, which is also included in the NetScaler, will be increased the employees productivity and reduced cost of telephone communication. to set some NetScaler Appliances, NetScaler Command Center is available separately that can provide centralized administration for the system configuration, event management, performance management, and administration of SSL certification.

Citrix NetScaler is available in three editions of the software types and six different kinds Appliances, which also vary in accordance with the needs of the application and system scalability desired.
