Changing the Billing Mode

CSS can be purchased in yearly/monthly mode. This mode is recommended for long-term users. The yearly/monthly billing mode can be configured during or after cluster creation.

If public access or Kibana public access is enabled for a yearly/monthly cluster, and the bandwidth is changed, you will be billed based on the new bandwidth. The yearly/monthly package cannot be unbound from the bandwidth before it expires. For details, see Product Pricing Details.

Changing the Billing Mode from Pay-per-Use to Yearly/Monthly

On the Clusters page, select a cluster.
Choose More > Switch to Yearly/Monthly in the Operation column.

If Switch to Yearly/Monthly is grayed out, you cannot change the billing mode in the current region.
On the Change to Yearly/Monthly page, configure Required Duration and Auto-renew as needed.
Click Pay Now. Confirm order details and click Pay.
Return to the Clusters page and check the current billing mode in the Billing Mode column.

Changing the Billing Mode from Yearly/Monthly to Pay-per-Use

On the Clusters page, select a cluster.
Choose More > Change to Pay-per-Use Upon Expiration in the Operation column.
In the Change to Pay-per-Use Upon Expiration dialog box, confirm the information and click Yes.
On the Clusters page and check the current billing mode in the Billing Mode column.

If the cluster billing mode is changed to pay-per-use during the yearly/monthly subscription period, the change will take effect when the yearly/monthly subscription expires.
The billing mode cannot be changed for a cluster that has expired or been frozen.

Renewal

The yearly/monthly billing mode can be automatically or manually renewed. You can enable auto-renewal when you create a cluster. If auto-renewal is not enabled during cluster creation, you can manually renew a cluster. Perform the following steps:

On the Clusters page, select a cluster.
Choose More > Renew in the Operation column.
In the displayed dialog box, click Yes to switch to the Renew page.
On the Renew page, configure Renewal Duration and Renewal Date.
Click Pay. On the payment page, confirm order details and click Pay.

A cluster that has expired or been frozen will be available after renewal.

Modifying Auto-Renew

Only yearly/monthly clusters can be renewed. If you use pay-per-use clusters, just ensure that your account has a valid payment method configured or a top-up account with a sufficient balance.

Log in to the CSS management console.
On the navigation pane in the left, select the target cluster type to view the cluster list.
For example, choose Clusters > Elasticsearch in the navigation pane to view the cluster list.
Select the cluster that you want to change auto-renew information and click More > Change Auto-Renew in the Operation column.
Confirm the cluster information in the dialog box and click OK.

In the Modify Auto-Renew page, modify the renew parameters by referring to Table 1, and click OK.
