A 3 Tier architecture describes a setup where multiple ObjectServers share read and write load. Dedicated Collection ObjectServer pairs reduce the write load of the Aggregation ObjectServer pair. Dedicated Visualisation ObjectServer pairs reduce the read load of the Aggregation ObjectServer pair. This is useful in high event rate environments.
