When you need to adjust the computing resources to meet business needs, you can scale existing clusters in cluster management.
Go to Cluster Management and click Clusters in the left pane to enter the cluster management page.
In the Action column of the cluster information, click Scale to pop up the cluster information box where you can modify the current node quantity. The beta version does not support simultaneous scale-up and scale-down. After confirming the information, click Execute.
After submitting the application, the Status of the cluster will be displayed as Scaling up or Scaling down. The scaling operation takes some time to complete, please wait patiently. When succeeded, the Status will become Available.
