ApsaraDB for Redis provides two billing methods: subscription and pay-as-you-go. You can change the billing method of a pay-as-you-go instance to subscription. Both billing methods allow you to modify the configurations of an instance.

Background

Fees are charged for instance scaling. For more information, see Pricing calculator.

Note
  • Both pay-as-you-go and subscription billing methods allow you to upgrade or downgrade an instance online at your convenience.
  • You can upgrade a non-cluster instance to a cluster instance or downgrade a cluster instance to a non-cluster instance. To change both the type and the specifications of an instance, you must change the instance type before you change the specifications. For example, to change an 8 GB standard instance to a 4 GB cluster instance, you must change the standard instance to an 8 GB cluster instance and then downgrade the storage capacity specifications of the cluster instance from 8 GB to 4 GB.
  • After you modify the configurations of the instance, the system starts to replicate data but does not switch your workloads. During this process, you can manage your workloads without disruption.

Procedure (pay-as-you-go)

  1. Log on to the ApsaraDB for Redis console.
  2. On the top of the page, select the region where the instance is located.
  3. In the left-side navigation pane, click Instance List to go to the Instance List page. Find the instance that you want to manage, click the More icon, and then select Change Configurations in the Action column for the instance.
  4. On the Update page that appears, modify the configurations and click Activate.

    If the configurations are modified, a message appears to notify you of the modification. Then, this pay-as-you-go instance is billed based on the new specifications in the current billing cycle.

Procedure (subscription)

  1. Log on to the ApsaraDB for Redis console.
  2. On the top of the page, select the region where the instance is located.
    Note If the price of the specifications is increased after the scaling process, select Upgrade in the next step. If the price of the specifications is decreased after the scaling process, select Downgrade in the next step. For example, the price of an 8 GB read/write splitting instance with five read replicas is higher than that of a 16 GB cluster instance. If you change a 16 GB cluster instance into an 8 GB read/write splitting instance with five read replicas, you must upgrade the instance.
  3. In the left-side navigation pane, click Instance List to go to the Instance List page. Find the instance that you want to manage, click the More icon, and then select Upgrade or Downgrade in the Action column.
  4. On the Update page, modify the configurations and click Pay.
  5. On the payment page, select an appropriate payment method and click Pay.

    After you settle the payment, a message appears to notify you of the payment. The instance scaling is completed.
