Yes, there are actually two ways of doing global traffic management (GTM):

GTM through ADCs: Some ADCs implement GSLB. In that case, ADCs have a real-time view of the hosting servers and forward requests based on the health and capacity of the data center.

GTM through DNS: DNS does GSLB by analyzing the IP location of the client. For each user requesting IP for a domain name (for example, www.educative.io), DNS-based GSLB forwards the IP address of the data center geographically closer to the requesting IP location.
