Citrix netscaler
introduction
Citrix NetScaler application delivery solutions use proven technology to combine the features and functions of traditional data center point products - load balancing, caching, compression, SSL acceleration, attack defense, SSL VPN - into a single network appliance, built from the ground up to maximize the performance of applications.
The Citrix NetScaler system can accelerate the delivery of enterprise Web application data by as much as 44x
Can improve the download times for public Web pages by up to 23x
Can reduce user response times by more than 97% and lower bandwidth consumption by 98%
Speeds Web application performance more than standards-based compression
Enhanced Web application performance with no modification to application code or changes to browser configuration.
The development and deployment of Web-based applications is rapidly driving the need for reliable and performance-optimised delivery of HTTP content to end users. When confronting Web performance challenges; enterprises typically deploy one or more traditional acceleration technologies, such as standard-based HTTP compression.
Although providing meaningful performance improvements, basic HTTP compression offers limited efficiency gains due to its inability to recognise and reduce redundancy in application content across multiple transmissions. Differential compression can accelerate the delivery of applications beyond what is possible with standard-based HTTP compression, by eliminating the transmission of redundant application data.
NetScaler doesn’t just enhance performance. By deploying a Citrix NetScaler solution your organisation will also benefit from improved application security, lower total cost of ownership and improved return on IT investment through increased operational efficiency
typical uses
Citrix NetScaler is deployed in situations where increasing demand for web application delivery, and vulnerability to malicious action are of concern to organisations. Specifically, Citrix NetScaler addresses the following areas:
Reduce Back-end Server Loads
Features such as TCP Buffering, TCP Offload, SSL Offload and Content Caching can provide significant reductions in back-end server loads. This allows existing infrastructures to cope with significant increases in future business growth.
Accelerate End-user Experience
In addition to the performance benefits gained by reducing the load on back-end servers; Citrix NetScaler implements HTTP and differential compression techniques to improve the responsiveness of web applications, and reduce overall bandwidth requirements.
Ensure Application Availability
By implementing layer 4 and layer 7 load balancing, Distributed Denial of Service (DDoS) attack protection and surge protection; Citrix NetScaler ensures that your web applications remain available.
cetus' experience
Cetus Solutions have again been selected as one of the UK’s Citrix NetScaler Spearhead Partners, helping to bring the newly launched Citrix NetScaler to the UK and European markets. We are currently working in partnership with over a dozen clients within the SME, Multi-National, Blue Chip and Public Sector arena; who are looking to benefit from this unique and powerful appliance.

quote
“Web trading has seen a huge increase in recent years, but sometimes the sheer volume of traffic can bring a site grinding to a halt. NetScaler dramatically accelerates performance without adding servers, bandwidth or consultants. Our remit is to bring this technology cost-effectively to SME businesses which have web-based applications, web access or on-line trading facilities.”
