Capacity
The Earize™ one to many system is designed to to shed load by bringing additional physical server hardware on-line as needed to satisfy demand.
Where one server computer can reasonably be expected to handle 3,000 clients, cascading to a second server computer would double that capacity and so forth.
You benefit from virtually infinite capacity and, while not a certainty, you have the confidence that Earize stands the best chance of meeting unexpectedly high audience demand for a show or event.
