Global Traffic Optimizer (GTO) enables SMA appliances to scale performance by deploying multiple appliances under the same service name. GHA eliminates a single point of failure and provides resilience whether customers deploy 2 SMA appliances in the same data center or clusters of up to 100 physical and virtual appliances across multiple data centers around the globe. In the event of a fail-over, users get connected to another appliance in the service. Their experience is frictionless and productivity is not impacted.
