• Billing methods

  PolarDB provides the subscription, pay-as-you-go, and Serverless billing methods to meet requirements in different scenarios. For more information, see Billing methods.

  • Subscription: a prepaid model. You select resources of fixed specifications and pay upfront when you create a cluster. The longer the subscription duration, the greater the discount. This method is suitable for businesses with consistent and long-term resource requirements.

  • Pay-as-you-go: a postpaid model. You select resources of fixed specifications but do not need to pay upfront when you create a cluster. You are billed based on your actual resource usage. This method is suitable for businesses with flexible resource requirements.

  • Serverless: a postpaid model. You do not need to select resources of fixed specifications or pay upfront when you create a cluster. In this billing method, PolarDB can dynamically scale resources based on the workload requirements. This method is applicable to businesses with fluctuating or unpredictable loads.
