The compute nodes of PolarDB for PostgreSQL clusters can be billed based on the pay-as-you-go or subscription billing method. The price of compute nodes varies based on the billing method and specifications. This topic describes the subscription prices of compute nodes.
The following tables describe the prices of a single compute node.
By default, a PolarDB cluster of Cluster Edition contains one primary node and one read-only node.
