cloud load balancing addresses issues relating to ttl reliance present during dns load balancing. dns directives can only be enforced once in every ttl cycle and can take several hours if switching between servers during a lag or server failure. incoming server traffic will continue to route to the original server until the ttl expires and can create an uneven performance as different internet service providers may reach the new server before other internet service providers. another advantage is that cloud load balancing improves response time by routing remote sessions to the best performing data centers.
