Introduction
The Cisco Global Site Selector 4490 is a networking product that provides site
selection services that are critical for disaster recovery deployments involving
Internet and intranet data centers. The GSS globally load balances traffic between
geographically distributed data centers managed by other server load balancers
(SLBs) such as Cisco Content Services Switches and Cisco Content Switching
Modules, IOS SLBs, and Cisco LocalDirectors. The GSS is the cornerstone of
disaster recovery in such distributed deployments and enables businesses to
confidently deploy global Internet and intranet applications with the knowledge
that users will be quickly routed to standby data centers should problems occur.
