Refund and renewal instructions

To release a subscription cluster of Volcano Engine E-MapReduce (EMR) before its expiration, you can apply for a refund to release the corresponding cluster in advance. This document introduces the refund and renewal features for subscription clusters.

Refund policy

tip

After the cluster is released, the cluster instance cannot be restored. Proceed with unsubscription with caution.

Billing methods

Unsubscription rules

Unsubscription methods

Subscription

For Subscription clusters, the fee is paid in advance based on the subscription period at the time of purchase. After unsubscribing from the cluster, Volcano Engine will refund the remaining actual cash paid amount of the order (the amount paid in cash by the user, excluding the portion offset by vouchers) to your Volcano Engine account balance according to the type of unsubscription request, the corresponding rules, and the cluster usage time. Used vouchers are not refundable.

  1. To unsubscribe from an EMR cluster when it is no longer needed after purchase, see Unsubscribe clusters
  2. After releasing the EMR cluster, you can go to Billing - Order Management to view refunds for EMR, ECS, and EIP.

Pay-As-You-Go

Pay-As-You-Go generates bills in real time based on actual usage, so refunds are not involved.
To stop using Pay-As-You-Go E-MapReduce, you can release the cluster after ensuring that your data has been backed up or migrated and that doing so does not affect your business. After the cluster is released, billing will cease.

Unsubscription does not apply

Renewal policy

Before a subscription cluster is automatically released, you can renew the cluster manually or automatically. After enabling automatic renewal, the system will automatically perform the renewal operation before the resource expires. No manual action is required, and you do not need to worry about resource and data deletion due to failure to renew on time. This document describes how to manually and automatically renew EMR clusters, as well as how to cancel automatic renewal.

prerequisites

  • The cluster to be renewed must be of the subscription type and in the normal Running state.
  • Automatic renewal supports the use of coupons.
  • After enabling automatic renewal, please ensure that your account balance remains sufficient.

Manual renewal

procedure

  1. Log in to EMR Console .
  2. In the left navigation pane, click Resource Management > on ECS. On the cluster list page, click the Renew button in the action column of the target cluster.
  3. Go to Expense Center**-Renewal Management** to confirm the renewal information. Resources under the cluster, such as E-MapReduce, ECS instances, Elastic Block Storage, and public IP addresses, must be renewed simultaneously.
  4. Select "I have read the renewal notice and agree to proceed with the above operation", click To pay, and complete the payment as prompted on the page.
  5. After successful payment, the expiration time of the renewed cluster will be updated to the new expiration time on the Cluster Overview page.

Unified expiration date

The unified renewal expiration date feature allows you to renew multiple subscription (non-calendar month) instances so that they expire on a fixed day each month. After configuration is complete, it applies to all Subscription (non-calendar month) instances. Each time you initiate a manual renewal, you can choose whether to align with the previously set unified expiration date.
For instructions, refer to Unified expiration date .

Specify expiration time

During EMR cluster usage, manual expansion of node groups may cause newly purchased instances to have expiration times inconsistent with the cluster. This can currently be resolved by specifying the expiration time, that is, by renewing to fully unify the expiration time of Subscription (non-calendar month) instances, including year, month, and day.

tip

  • The minimum date for specifying the expiration time is the date one month after the latest expiration time among the renewal instances (23:59:59).
  • After specifying the expiration time, the renewal billing period is calculated to the day, with the monthly price converted to a daily rate. The specific renewal amount is subject to the order confirmation page.
  • Only non-calendar-month Subscription instances can specify the expiration time during manual renewal. Instances billed by day or calendar-month Subscription instances do not currently support this feature.
  • Expiration time can only be specified during manual renewal. Automatic renewal is still executed according to the preset single renewal cycle.

procedure

  1. Log in to EMR Console .
  2. In the left navigation bar, click Resource Management > on ECS, then on the cluster list page, click the Renewbutton in the Operation column of the target cluster.
  3. On the Billing Center - Renewal Management page, select Specify expiration time, and choose to renew to a specific date.
  4. Click To pay to complete the renewal.

Automatic renewal

Before a Subscription instance expires, you can enable automatic renewal. Seven days before the instance expires, the system will automatically deduct the renewal fee from your account balance. Please ensure your balance is sufficient. You can also select the "Automatic renewal" option when purchasing a Subscription cluster. Automatic renewal can also be enabled after purchasing a Subscription cluster.
After enabling automatic renewal, if your account contains available vouchers, the system will prioritize using vouchers for renewal.
