How NetScaler works
Citrix NetScaler is an all-in-one web 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:
NetScaler forms a complete foundation for service delivery
NetScaler comes in both built-for-purpose MPX-series hardware appliances and 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.
