How Is Auto Scaling Billed for an MRS Cluster?

The price displayed at the bottom when you purchase an MRS cluster will not include the auto scaling fee if you specify only the auto scaling range for the Task nodes without configuring the instance count. The price will include the auto scaling fee after you configure both the auto scaling range and instance count.

If you add nodes through the auto scaling function, the added nodes will be billed by the actual usage duration per hour regardless of whether the cluster's billing mode is yearly/monthly or pay-per-use mode.
