Citrix NetScaler is a set of appliances that form a web application delivery solution, which has the capacity to speed-up application performance by a maxiumum of 5x. Citrix NetScaler also constantly decreases data center costs, and enhances the security of your web applications. Applications available range from, the basic level, series 7000 and up to the most modern, MPX, which has the capabilities of 15 gigabits per second of throughput in both layers 4 and 7 with the highest constant use of all the functional modules. Perfect for network management for all enterprises that require acceleration in the running of existing web applications the Citrix Netscaler increases security in web applications and enhances the availability of the web application.
Citrix NetScaler is the most efficient and secure way to maximize the delivery of web application and is one of the few IT products on the market that still produces the most amazing performance that can give benefits to any organisation.
NetScaler merges the features and functions of conventional data centre point devices into one single network appliance, built from the ground up to optimize the performance of the following web applications aspects.:
Load balancing,
Caching,
Compression,
SSL offload and acceleration,
Attack defence (DoS etc.),
SSL VPN
From resellers point of view, NetScaler is a very technical sale and the results speak for themselves. Getting the customer to evaluate the product in a live environment (or as close to it as feasibly possible) is key to the success of the opportunity. Over 80% of evaluations result in a purchase order.From an end user perspective, Citrix NetScaler products provide:
Maximized application performance
End-to-end application security
Continuous application availability
Reduced cost of operations
Citrix NetScaler products enhance the performance of Oracle, PeopleSoft, SAP, Siebel, Outlook Web Access, e-commerce applications and custom applications 70% or more, while also enhancing security and intensively reducing operational expenditure.
Citrixt NetScaler utilises technology to maximize the TCP acceleration and accelerate the performance of web applications by up to five times. Citrix AppCompress and Citrix AppCache effectively transmit data compression and keep the static and dynamic contents on transitory storage (caching) to quicken the response from the web application. NetScaler TCP optimization provides network management solutions to settle the inconveniences of high latency, crammed network links and is transparent to the user and the server and only necessitates minimal of configuration or in some cases no configuration. To Real-Time Monitoring and identify all the Historical Page-Level end-users that are available on the Citrix EdgeSight for NetScaler. Citrix NetScaler allows for the reduction in the cost of delivering web applications by lowering the number of servers required, and maximise the use of network bandwidth available. MPX is the latest series of Citrix NetScaler, and delivers numerous 10GE ports and power to run all the modules with the traffic throughput of 10 gigabits even in the layer 7. This performance offers the capability to prevent the network segmentation that is not required that can decrease the number of switches and other elements, consequently there can be savings in the cost of infrastructure. With the AppExpert Visual Policy Builder there is no need for coding or script when making application delivery policies. Also, the current NetScaler can lower the cost of operations with some ability to consolidate in one solution. Using the Citrix EasyCall, which is part of the NetScaler package, will increase 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 delivers protection against assaults on the application layer, and assists in the prevention of the event of leakage or theft of customer data and companies data that are valuable. Citrix now have some capabilities such as open proxy for users who have permission, close proxy for users who do not have the permission with the Citrix Request Switching, which also is equipped with high-performance, and built-in defenses against denial of service attack (DoS). With configuration of the Surge Protection function and Priority Queuing, I is easier to manage the surges on the application's traffic that inflict a web server application.
Citrix NetScaler provides an obvious direction of the user requirements to make sure of the maximum distribution of traffic is achieved. If more information is required on the layer 4 - Protocol and Port Number or traffic management policies for TCP applications can all refer to the Application-Layer content. An administrator can carry out traffic segmentation on applications step by step to the information held in the TCP pay-load or the HTTP request body. 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 facility to create health checks the server application availability by making sure that high-needs (requests) the user is directed only at the appropriate time depending on the behaviour of the server. While other solutions declare that they can enhance the performance of Web-enabled applications, only Citrix NetScaler products optimise the performance and security of Web-enabled applications. In addition, since NetScaler's single, integrated device takes the place of a number of point solutions, overall network infrastructures are considerably made easy, and total operational costs are significantly decreased.
