This chapter discusses the Virtual Traffic Manager's Global Load Balancing (GLB) capability.

## Introduction and Prerequisites

GLB is designed to provide business continuity and improved performance across globally distributed locations. This capability is based upon a technique known as Global Server Load Balancing (GSLB). The Virtual Traffic Manager uses geographic load balancing and failover functionality to enable the distribution of traffic across these locations based on availability, performance and user-defined rules.

This chapter describes how to plan and configure GLB in your Virtual Traffic Manager deployment. To perform the configuration described here, you must be familiar with standard system administration tasks, including networking and DNS administration. For a background on DNS, see [DNS Primer](docId\:j3vd9BBvUSU3Cr5GWTfjT).

For further details about the principles of GSLB, see [About Global Server Load Balancing](docId\:xGkmre7PaUqfTwMZsUCRP). Ivanti recommends that you also refer to the background whitepapers and documentation published on [www.ivanti.com](http://www.pulsesecure.net) and the Ivanti Community Web site at [https://forums.ivanti.com/s/?language=en\_US](http://kb.pulsesecure.net).
