This paper explores the challenges of maintaining the availability and security of applications during disasters and disruptions in order to distill the characteristics of an ideal solution. It subsequently reveals how global server load balancing and secure remote access capabilities available from Citrix, particularly in the form of Citrix® NetScaler®, are a complementary, logical extension to XenApp. As will be illustrated, the result is a robust solution that ensures application availability and conveys a wide range of technical and business benefits.
