If an ES cluster is no longer needed as your business changes, you can terminate it in the console to avoid further fees. If the cluster cannot meet your needs, you can also scale it to the appropriate specifications by adjusting its configuration. For more information, see Adjusting Cluster Configuration.
Log in to the ES Console.
You can terminate a cluster either on the cluster list page or the cluster details page.
In the cluster termination dialog box, click OK and the system will clear the cluster data and repossess the resources. Data can not be recovered once cleared.
