Abstract: The disclosure herein describes a system for providing distributed global server load balancing (GSLB) over resources across multiple data centers. The system includes a directory group comprising one or more directory nodes and a plurality of GSLB nodes registered to the directory group. A respective GSLB node is configured to provide GSLB services over a respective portion of the resources. A directory node includes a domain name system (DNS) query-receiving module configured to receive a DNS query from a client, a node-selecting module configured to select from the plurality of GSLB nodes a first GSLB node based at least on the DNS query, and a DNS query-responding module configured to respond to the DNS query to the client using an address of the selected first GSLB node, thereby facilitating the selected first GSLB node in performing GSLB while resolving the DNS query.
