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 pay-as-you-go 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.
