 ### Horizontal autoscaling (private preview) {#horizontal-autoscaling}
 
-Horizontal autoscaling automatically adjusts the number of replicas in a ClickHouse Cloud cluster, scaling out aggressively when demand spikes and scaling in gradually as load drops — so teams with variable, high-concurrency workloads no longer need to manually right-size clusters. Private preview scales on concurrent query count; CPU and memory signals are planned for public beta. Available to Enterprise and Scale tier customers on ClickHouse 26.2+.

+Note: For the intial GA launch, horizontal and vertical autoscaling are mutually exclusive. Horizontal autoscaling will only activate when vertical autoscaling is disabled (i.e., the service is set to a fixed size). The same applies to vertical autoscaling being enabled when the number of replicas is fixed. This behavior will become more flexible in future releases.
