If all nodes of your cluster are pay-as-you-go Elastic Compute Service (ECS) instances, you can stop the cluster when you do not use it. This helps you save costs.
Stop a cluster
You can stop only a cluster that is in the Running or Exception state.
If you stop a subscription compute node, its billing is not affected. If you stop a pay-as-you-go compute node for which you have enabled the economical mode, you are no longer charged for its computing resources. For more information, see Economical mode.
