The Start/Stop VMs during off-hours feature start or stops enabled Azure VMs. It starts or stops machines on user-defined schedules, provides insights through Azure Monitor logs, and sends optional emails by using [action groups](../azure-monitor/alerts/action-groups.md). The feature can be enabled on both Azure Resource Manager and classic VMs for most scenarios.

This feature uses [Start-AzVm](/powershell/module/az.compute/start-azvm) cmdlet to start VMs. It uses [Stop-AzVM](/powershell/module/az.compute/stop-azvm) for stopping VMs.

A cluster's scale is determined by the quantity of its VM nodes. For all cluster types, there are node types that have a specific scale, and node types that support scale-out. For example, a cluster may require exactly three [Apache ZooKeeper](https://zookeeper.apache.org/) nodes or two Head nodes. Worker nodes that do data processing in a distributed fashion benefit from the additional worker nodes.

Depending on your cluster type, increasing the number of worker nodes adds additional computational capacity (such as more cores). More nodes will increase the total memory required for the entire cluster to support in-memory storage of data being processed. As with the choice of VM size and type, selecting the right cluster scale is typically reached empirically. Use simulated workloads or canary queries.

You can scale out your cluster to meet peak load demands. Then scale it back down when those extra nodes are no longer needed. The [Autoscale feature](hdinsight-autoscale-clusters.md) allows you to automatically scale your cluster based upon predetermined metrics and timings. For more information on scaling your clusters manually, see [Scale HDInsight clusters](hdinsight-scaling-best-practices.md).
