AnalyticDB for MySQL:ACU-hour plans

Offset description

Offset objects

• Reserved computing resources, reserved storage resources, and elastic resources of pay-as-you-go clusters.
• Elastic resources of subscription clusters.

Offset rules

• You can use an ACU-hour plan to offset the amount of resources that are consumed by a cluster that resides in the same region as the plan.
• You can use the same ACU-hour plan for multiple clusters that reside in the same region.
• During the validity period of an ACU-hour plan, the amount of resources that are consumed by clusters is offset from the ACU-hour plan on an hourly basis. If the ACU-hour plan does not have sufficient resources, you are charged for additional resources on a pay-as-you-go basis.
• The validity period of an ACU-hour plan is one calendar month. After the validity period of an ACU-hour plan elapses, you cannot use the remaining resources of the plan. For example, if you purchase an ACU-hour plan on April 20, the plan is not valid from May 1.
• You can purchase and use multiple ACU-hour plans at the same time. You cannot renew, upgrade, or downgrade ACU-hour plans.

Offset examples

• Example 1
  You purchase a subscription Data Lakehouse Edition (V3.0) cluster in the China (Hangzhou) region. The subscription duration is three months.

  • Reserved computing resources: 32 ACUs.
  • Reserved storage resources: 24 ACUs.
  • Elastic resources: An elastic scaling plan is scheduled to scale the resources of an interactive resource group by 100 ACUs per month. The scaling cycle is 1 hour.
  • ACU-hour plan: An ACU-hour plan that provides 1,000 ACU-hours is purchased. The subscription duration is three months.

  Offset method: For a subscription cluster, you can use ACU-hour plans to offset only the amount of elastic resources. During the 3-month subscription duration, 1,000 ACU-hours are allocated per month to offset 100 ACU-hours of elastic resources that are consumed by the cluster. You cannot use the remaining 900 ACU-hours in the ACU-hour plan.

• Example 2
  You purchase a pay-as-you-go Data Lakehouse Edition (V3.0) cluster in the China (Hangzhou) region. The cluster is used for one month.

  • Reserved computing resources: 32 ACUs.
  • Reserved storage resources: 24 ACUs.
  • Elastic resources: A job resource group that provides 0 ACUs of reserved resources is created. The job resource group is used to run a Spark job that uses 2 cores and 4 GB memory (2 × 0.8 ACUs) for 10 hours.
  • ACU-hour plan: An ACU-hour plan that provides 10,000 ACU-hours is purchased. The subscription duration is one month.
  The following resources are consumed within one month:

  • Reserved computing resources: 32 ACUs × 30 days × 24 hours = 23,040 ACU-hours.
  • Reserved storage resources: 24 ACUs × 30 days × 24 hours = 17,280 ACU-hours.
  • Elastic resources: 2 × 0.8 ACUs × 10 hours = 16 ACU-hours.

  Total resources consumed = 23,040 ACU-hours + 17,280 ACU-hours +16 ACU-hours = 40,336 ACU-hours.

  Offset method: For a pay-as-you-go cluster, you can use ACU-hour plans to offset the amount of reserved computing resources, reserved storage resources, and elastic resources. The ACU-hour plan is used to offset a total of 10,000 ACU-hours of resources, and you are charged for the additional 30,336 ACU-hours on a pay-as-you-go basis.

The remaining quota cannot be carried over to the next month, and the quota is reset when the next month starts. For example, you purchase an ACU-hour plan that provides 1,000 ACU-hours on May 1 for three months. In this case, you can use 1,000 ACU-hours to offset the amount of cluster resources per month in May, June, and July.

6. On the Confirm Order page, check your order information, read and select the Terms of Service, and then complete the payment. If your payment is successful, the ACU-hour plan immediately takes effect.
