Global server load balancing

There are many mechanisms to handle the flow of traffic between multiple sites. Nearly all of them rely on the manipulation of DNS information. DNS information can sometimes take hours to update across the globe. If production sites must failover to redundant sites, waiting hours for traffic to pass again is not an option. Global server load balancing enabled the configuration of pre-planned actions to take place in the event of failure. GSLB required expensive publicly accessible devices at each site. Security experts were also required as part of a successful solution to keep devices safe from continuous hacking attempts.

Expensive, traditional, device-based GSLB deployments can be deployed as cloud GSLB services, ...
