The Citrix NetScaler is an all-in-one application delivery controller that makes applications run five times better, reduces web application ownership costs, optimizes the user experience, and makes sure that applications are always available by using:
- Proven application acceleration such as HTTP compression and caching.
- High application availability through advanced L4-7 load balancer.
- Application security with an integrated application firewall.
- Server offloading to significantly reduce costs and consolidate servers.
Solutions that require multiple point products such as discrete load balancers, web application firewalls, and SSL VPN are difficult and far more costly to deploy and manage when compared to the NetScaler all-in-one web application delivery controller solution.
The best application delivery controllers must be flexible
NetScaler is available in two form factors. NetScaler comes in built-for-purpose MPX-series hardware appliances powered by Citrix nCore technology for the most demanding applications. NetScaler is also available in an economical virtual appliance, Citrix NetScaler VPX, that operates with any Intel®-VT or AMD®-v capable server using Citrix XenServer technology. Customers can start at VPX and grow into the MPX-series or deploy both within the same environment, an option that is especially valuable for multi-tenant environments like those of application service and cloud providers.
To help protect your investment, NetScaler Pay-as-You-Grow offers a simple, on-demand licensing model to easily scale NetScaler performance from VPX through MPX deployments, provide investment protection, avoid costly hardware upgrades, and minimize TCO.
How Citrix web application delivery controllers work
Deployed in front of web servers, NetScaler application delivery controllers can handle up to 18 Gbps using a combination of built-in load balancing and context switching for intelligent traffic management. NetScaler multiplexes thousands of incoming connections to a smaller number of back-end server farm sessions within your datacenter and employs HTTP compression, static and dynamic content caching, and network WAN protocol optimization to accelerate application delivery by five times and more.
Application security is provided with a built-in web application firewall which uses a positive security model and automatically learns proper application behavior to ensure protection against day-zero attacks. Encrypted SSL traffic is no problem as NetScaler provides not only SSL acceleration but full SSL VPN tunnel support with certificate management and granular access control.
To provide advanced warning in the event of a drop in user application performance, NetScaler monitors application performance, allowing administrators to take proactive action to guarantee that solid user experience is maintained. The integrated server monitoring and health checks ensure that applications and databases are functioning properly and at maximum throughput, performance, and efficiency.
