This topic describes how to upgrade or downgrade the configurations of a MaxCompute subscription instance. You can scale out the resources allocated to a subscription instance to handle increased workloads or scale in resources to reduce costs.

Upgrade resource configurations

If the resources allocated to your MaxCompute subscription instance cannot handle the required workloads, you can upgrade the resource configurations to scale out the resources.

  1. Log on to the MaxCompute console, and select the region where your MaxCompute project is located in the top navigation bar.
  2. Click the Resource management tab. In the Annual and monthly resources section, click Upgrade in the Actions column.

  3. On the Upgrade/Downgrade page, specify the number of compute units (CUs) that you require, read and select MaxCompute (Subscription) Agreement of Service, and then click Buy Now.
  4. On the Unpaid Orders page, confirm the order and click Subscribe to complete the upgrade.

    After you submit the order, go to the Orders page to view the details of the upgrade order.

Downgrade resource configurations

You are charged for idle resources. If your actual workloads do not use all of the resources that are allocated to your MaxCompute subscription instance, you can perform the following steps to release the idle resources to reduce costs:

  1. Log on to the MaxCompute console, and select the region where your MaxCompute project is located in the top navigation bar.
  2. Click the Resource management tab. In the Annual and monthly resources section, click Downgrade in the Actions column.

    After you submit the order, click the Orders page to view the details of the downgrade order.

    Note If you downgrade resource configurations immediately after an upgrade, you may receive only part of the refund due to one of the following reasons:
    • A discount is applied to the order you placed when you purchased the instance. For example, you placed a one-year subscription order. A discount of 15% is applied to the order. Therefore, if the price is USD 154.7, you paid USD 131.5. In this case, the refund is calculated based on the amount after the discount was applied, which is USD 131.5.
    • A voucher is applied to the order you placed when you purchased the instance. In this case, the refund does not include the vouchers that you used.
