GEO LoadMaster (GLM) offers the ability to move past the single datacenter, allowing for multi datacenter load balancing and high availability. GLM ensures that even when a primary site is down, traffic is diverted to the disaster recovery site. GEO LoadMaster also includes the ability to ensure clients seamlessly connect to their fastest performing and geographically closest datacenter.

GLM load balances using Domain Name Services (DNS) technology. Using DNS to direct traffic allows you to load balance to any Internet Address and ignore protocol level configuration on your load balancing devices. Internet clients using the GLM intelligent load balancer are geographically coded in real-time allowing you to make decisions on which Internet Address to offer to a customer.
