This topic describes the billing methods and price details of AnalyticDB for MySQL.

Billing methods

AnalyticDB for MySQL supports the Subscription and Pay-as-you-go billing methods.

Billing option Description
Subscription
  • The subscription billing method is a pre-payment plan. You must pay an upfront subscription fee when you purchase a cluster.
  • We recommend that you select this option for long-term use because it is more cost-effective than the pay-as-you-go billing method. Larger discounts are provided for longer subscription periods.
  • You cannot change the billing method of a cluster from subscription to pay-as-you-go.
Pay-as-you-go
  • The pay-as-you-go method is a post-payment plan. The system generates a bill every hour and deducts the amount from your account balance based on the cluster specifications.
  • Pay-as-you-go is suitable for scenarios where you have short-term requirements, such as testing. This is because you can immediately delete the cluster to reduce costs after you use the cluster to fulfill the intention. After the resource usage becomes stable, you can log on to the AnalyticDB for MySQL console. In the left-side navigation pane, click Clusters. On the Clusters page, click the V3.0 Clusters tab. Then, click Switch to Subscription Billing in the Actions column corresponding to a cluster. This way, the billing method of the cluster is changed from pay-as-you-go to subscription.

Billing rules and prices

  • Elastic mode for Cluster Edition
    Note
    • If the specifications of a cluster are 8 cores and 32 GB or 16 cores and 64 GB, the cluster contains only one node and does not ensure high availability.
    • You can scale out resources of a cluster whose specifications are 32 cores and 128 GB or higher Therefore, the pricing of elastic computing resources applies only to such clusters. For more information about the resource scale-out feature, see Scale out resources.

Examples

Note In the following examples, the total prices are calculated based on different prices for the corresponding regions.
Scenarios
  • Scenario 1

    A cluster is deployed in the China (Hong Kong) region. It contains four compute nodes (64 cores and 256 GB of memory in total) that are purchased by using the subscription billing method for 6 months.

    The pre-payment amount is calculated based on the following formula: USD 678.3 per node per month × 4 nodes × 6 months = USD 16,279.2

  • Scenario 2

    A cluster is deployed in the Malaysia (Kuala Lumpur) region. It contains two compute nodes (32 cores and 128 GB of memory in total) that are purchased by using the pay-as-you-go billing method for 10 days. Each hour, 1,000 GB of hot data and 3,000 GB of cold data are stored in the cluster.

    The post-payment amount is calculated based on the following formula: (USD 1.2326 per node per hour × 2 nodes + USD 0.000892 per GB per hour × 1,000 GB + USD 0.000042 per GB per hour × 3,000 GB) × 24 hours × 10 days = USD 836

  • Scenario 3
    A cluster is deployed in the US (Silicon Valley) region. It contains 6 compute nodes (96 cores and 384 GB of memory in total) that are purchased by using the subscription billing method for 3 months and 6 elastic compute nodes (96 cores and 384 GB of memory in total) that are purchased by using the pay-as-you-go billing method for 100 hours. The payment amounts are calculated based on the following formulas:
    • Pre-payment amount: USD 488.012 per node per month × 6 nodes × 3 months = USD 8,784.216
    • Post-payment amount: USD 1.307175 per node per hour × 6 nodes × 100 hours = USD 784.305

    The total amount is calculated based on the following formula: USD 8,784.216 + USD 784.305 = USD 9,568.5
