PolarDB:Billing

PolarDB for cloud-native databases uses a storage-compute decoupled architecture. When you use a PolarDB cluster, compute nodes and storage space are billed separately.

• Billing methods

  PolarDB for cloud-native databases provides three billing methods to meet your needs in different scenarios: subscription, pay-as-you-go, and Serverless. For more information, see Billing methods.

  • Subscription: An upfront payment model. When you create a cluster, you select resources with defined specifications and pay for them in advance. The longer the subscription period, the larger the discount. This method is suitable for businesses with stable, long-term needs.

  • Pay-as-you-go: A pay-as-you-go model. When you create a cluster, you select resources with defined specifications. You do not need to pay in advance. You are billed for the resources that you use. This method is suitable for businesses with flexible needs.

  • Serverless: A pay-as-you-go model. When you create a cluster, you do not need to select resources with defined specifications or pay in advance. PolarDB clusters can dynamically scale resources based on workload changes. This method is suitable for businesses with fluctuating, uncertain, or unpredictable workloads.

  If the billing method for your PolarDB cluster no longer meets your business requirements, you can switch the billing method at any time.
