What is Global Server Load Balancer?
A global server load balancer is a tool or resource used to distribute workloads to aid in business continuity and comprehensive recovery. This tool can distribute traffic on a network using strategies such as DNS or HTTP redirects.
On a general level, using global server load balancing involves creating geographic or other strategies for routing traffic and distributing workloads across an entire IT architecture. This can include traffic being routed to one of several data centers or to a cloud gateway. Disruptions to the IT architecture may require such a redirection of the data traffic in order to protect the system from a partial or complete crash.
