# Simulator load balancing

**coherence** allows us to use multiple Simulators to split up a large game world with many entities between them. This is called **spatial load balancing.** Please refer to the [section about simulators](https://docs.coherence.io/0.9/simulators/simulators-overview) for more information.

{% hint style="info" %}
Our cloud services currently only support associating one Simulator to a Room or World. This will be extended in the near future. Enterprise customers can still run multiple Simulators in their own cloud environment.
