ApsaraDB for Redis supports the subscription and pay-as-you-go billing methods.

Billing method Description Note
Subscription
  • If you select the subscription billing method, you must pay for the instance when you create the instance.
  • If you purchase a subscription instance with a one-year subscription period, a 15% discount is offered.
  • During the subscription period, you can only upgrade or downgrade the instance, but cannot release the instance.
  • You cannot switch the billing method of an instance from subscription to pay-as-you-go.
Pay-as-you-go
  • The billing cycle is one hour. If you use an instance for less than one hour, you are charged for the fees of one hour.
  • If you change the specifications of an instance within one billing cycle, the instance is billed based on the largest capacity used during the cycle.

    For example, if your instance capacity is 1 GB at 01:10, and changed to 8 GB at 01:20, and then to 2 GB at 01:50, the instance is billed for the 8 GB capacity during the billing cycle between 01:00 and 02:00.

  • The system generates the bill within three hours after the current billing cycle. The specific bill time is subject to the system accounting time.

    For example, a bill for the billing cycle of 09:00 to 10:00 is generated before 11:00.

  • After a bill is issued, the fee is automatically deducted from your account.
  • You can release a pay-as-you-go instance at any time. No fees are charged for the released instance.
  • You can change a pay-as-you-go instance to a subscription instance. The system starts the subscription billing method immediately after the change. For more information, see Change the billing method to subscription.
Note
  • An ApsaraDB for Redis instance is billed based on the specifications of the instance, instead of the consumed cache space.

    For example, if you purchase an ApsaraDB for Redis instance of 2 GB memory and store 256 MB of data on this instance, the instance is billed for the 2 GB memory capacity.

  • The internal network traffic that is consumed by an ApsaraDB for Redis instance is free of charge. No fees are charged for data transmission between an Elastic Compute Service (ECS) instance and an ApsaraDB for Redis instance.
