The computing resources of PolarDB for PostgreSQL Distributed Edition consist of compute nodes and data nodes. The pay-as-you-go and subscription billing methods are supported. Prices vary based on the billing method.
You can specify General-purpose or Dedicated specification types for computing resources.
General-purpose: The cluster shares idle computing resources such as CPUs with other clusters on the same server. This enhances cost efficiency.
Dedicated: The cluster does not share allocated compute resources such as CPUs with other clusters on the same server. This improves the reliability and stability of the cluster.
When you purchase a cluster, the default number of read-only compute nodes or data nodes is 1. In this case, one read-only compute node or data node is added to the primary node. By default, the specifications of the read-only node are the same as the specifications of the primary node in the primary zone or the primary data center. You are separately charged for the read-only node.
You can receive a 25% discount for the added read-only node.
Pay-as-you-go
If you use the pay-as-you-go billing method for a cluster, you do not need to pay upfront fees when you create the cluster. You are charged for the computing and storage resources that you use. You are charged for the compute nodes and data nodes in a cluster per hour. The fees are deducted from your account balance on an hourly basis.
The following section describes the pay-as-go pricing of compute nodes in specific regions.
The following tables describe the prices of a single compute node.
By default, PolarDB for PostgreSQL Distributed Edition addes one read-only node to each compute node or data node to improve the read performance.

Subscription
If you use the subscription billing method for a cluster, you must pay for compute nodes when you create the cluster.
The following section describes the subscription pricing of compute nodes in specific regions.
The following tables describe the prices of a single compute node.
By default, PolarDB for PostgreSQL Distributed Edition addes one read-only node to each compute node or data node to improve the read performance.
