Global server load balancing

HAProxy Enterprise can serve as an authoritative Domain Name System (DNS) server in a limited capacity, specifically for implementing global server load balancing (GSLB). This lets you respond to DNS queries with the IP address(es) assigned to a datacenter that is the best match for the end user, such as the one that is geographically closest to them. Or, you can configure DNS to return the address of a secondary datacenter if the primary becomes inaccessible.
