Introduction

Citrix NetScaler application delivery solutions combine the features and functions of traditional data center point products - load balancing, caching, compression, SSL acceleration, and attack defense - into a single network appliance, built from the ground up to maximize the performance of mission-critical applications.

The Citrix NetScaler LB products are built on Citrix’s patented Request Switching™ architecture, the industry’s only wire-speed technology that handles every application request based on powerful user-defined policies. The Citrix NetScaler application-aware policy engine, AppExpert™, allows the creation of detailed policy-based decisions for individual requests, irrespective of connections. AppExpert lets administrators build sophisticated application request handling policies that enable powerful, comprehensive application-based features.

As business entities have begun to rely enormously on the Citrix NetScaler solutions to deliver service continuity and to ensure the secure transaction of business, the smooth functioning of the NetScaler appliance has become super-critical in Citrix infrastructures today. Round-the-clock monitoring of NetScaler products, proactive error reporting, and swift error-clearance are a must to ensure that the Citrix NetScaler is always up and running, and is well enough to attend to application requests from users. This is where the eG Enterprise lends helping hands to administrators.
