Greetings,

 

A few of the outstanding benefits would be the ability to actually monitor and load balance the IP addresses being resolved. A few examples:

 

  • Availability: If you hand out IP address 1.1.1.1 for example.com and GTM determines that service is no longer available (network interruption), a backup address for an available service, say 2.2.2.2 can be chosen and handed out.

  • Load balancing: Hand out 1.1.1.1 and 2.2.2.2 evenly, or 2.2.2.2 twice as often as 1.1.1.1 if the servers are different platforms / capacities. Hand out 1.1.1.1 to customers in Japan and 2.2.2.2 to customers in America.

     

  • DDoS protection: GTM (F5 TMOS) offers advanced DDoS protection.

     

  • DNSSEC: Easier DNSSEC management abilities.

This is a great intro article:

Hope this is helpful!
