Global Server Load Balancing (GSLB) allows you to coordinate how traffic is processed among multiple data centers. A Barracuda Load Balancer ADC acts as a controller, selecting the location to which traffic is directed based on the parameters that you configure and the health of the data centers. This allows you to allocate the work among multiple data centers and to ensure that if one data center fails then traffic is redirected automatically to a functioning data center.
