Techopedia explains Global Server Load Balancer
On a general level, using a global server load balancer involves creating geographic or other strategies to route traffic and spread workloads over an entire IT architecture. This may involve routing traffic toward one of multiple data centers or toward a cloud gateway. Disruptions to the IT architecture may require this kind of traffic rerouting in order to protect the system from partial or complete crashing.
