+## Cluster functionality
+
+A cluster in the Business Studio is a group of business engines with the same token connected to the same configuration database and Grafana instance.
+
+Clusters are displayed in the left-hand side menu. Each cluster has two pages.
+
+### Load balancing
+
+Here, you can see the number of business engines in the cluster and the number of scheduled alerts. Then, down below, you have a list of business engines with Grafana dashboards they serve. Each dashboard is displayed with a list of created alerts.
