Citrix NetScaler enables the datacenter to become an end-to-end service delivery fabric to optimise the delivery of all web applications, cloud-based services, virtual desktops, enterprise business applications, and mobile services. Available as a physical or virtual appliance, Citrix NetScaler is an application delivery controller that:

  • Accelerates internal and external-facing applications up to five times.
  • Optimises application availability through advanced Layer-4 through Layer-7 traffic management.
  • Increases security with an integrated application firewall.
  • Substantially lowers costs by increasing web server efficiency.

Citrix NetScaler is a comprehensive system deployed in front of application and database servers that combines high-speed load balancing and content switching with:

  • Application acceleration
  • Highly-efficient data compression
  • Static and dynamic content caching
  • SSL acceleration
  • Network optimization
  • Application performance monitoring
  • Robust application security

NetScalers are often mistaken as hardware load-balancers that can do some network optimisation and caching, however they are much more powerful and capable and an essential core system for a wide range of IT delivery applications. Here are some examples of the wide ranging applications

Protection of your Customers and Company information is paramount. By centralising your exposed endpoints to the Internet via NetScalers you can create auditing, logging and reporting policies to record all requests for data. Applying NetScaler AppFirewall policies not only allows you to protect your websites and services from common vulnerabilities such as SQL Injection and Cross Site Scripting (XSS) but extends much further into data leakage protection and PCI-DSS compliance. All this happens on the NetScaler itself, without adding any more load to your existing infrastructure.

Citrix NetScaler is available in both high-performance hardware appliances as well as flexible software-based virtual appliances that support popular hypervisors and run on off-the-shelf servers.

The adoption of cloud computing creates significant networking challenges, including the need to provide self-service capabilities and deliver elastic provisioning of application delivery services. As a software-based virtual appliance, NetScaler VPX enables rapid on-demand provisioning in both public and private cloud infrastructures. The solution’s RESTful APIs are leveraged by leading cloud providers to develop self-service capabilities and dramatically reduce overall deployment cost.

An efficient enterprise cloud network makes network resources elastic so that performance can be scaled on-demand. With TriScale technology, Citrix enables a genuine revolution with an unrivaled set of capabilities that smartly scale application and service delivery infrastructures affordably and easily.

Citrix NetScaler delivers 100% application availability, enhanced end-to-end performance, advanced application-layer attack protection, and improved server efficiency – all in a single device, with a unified, easy-to-define policy.

NetScaler VPX is also ideal for small to mid-size businesses to improve widely-deployed applications, such as XenDesktop and XenApp, as well as popular applications including Microsoft Exchange and SharePoint. Support for AppExpert templates enables fast and easy configuration for these and other applications.

NetScaler VPX can be deployed within development, testing and staging environments, prior to promotion into production. This approach supports an improved assurance process and eliminates the cost and logistics of dedicating physical appliances for use within application development areas. NetScaler policy configurations defined in the development lab can easily be moved into production. The inherent flexibility of the virtual appliance model enables NetScaler VPX to be evaluated as part of the full application lifecycle process.
