Citrix commissioned Forrester Consulting to conduct a Total Economic Impact™ (TEI) study and examine the potential return on investment (ROI) enterprises may realize by deploying NetScaler. The purpose of this study is to provide readers with a framework to evaluate the potential financial impact of the NetScaler on their organizations, based on the results from existing customers. Readers should be able to develop their own business case to measure possible improvements in application reliability and deliver improved services, all to win, serve, and retain customers. To better understand the benefits, costs, and risks associated with a NetScaler implementation, Forrester interviewed several customers with multiple years of experience using NetScaler. They primarily or exclusively have purchased NetScaler SDX devices, which provide multitenancy options for organizations to consolidate application delivery controller (ADC) instances while still delivering a high-availability solution.
