Why do RDS Cluster Edition and RDS Basic Edition have different storage unit prices for the same storage type?
Different architectures and storage billing methods
RDS Basic Edition uses a single-node architecture without a standby node. Its data reliability depends on the multi-replica mechanism of cloud disks.
RDS Cluster Edition uses an architecture with one primary node and multiple standby nodes. In addition to the multi-replica mechanism of high-performance cloud disks, its high-availability architecture further improves data reliability and system availability. The standby nodes require one or more additional sets of cloud disks.
These architectural differences affect resource scheduling and cost allocation. Storage fees are calculated as follows:
RDS Basic Edition: Storage fee = Storage unit price per instance × Storage capacity per instance × Duration
RDS Cluster Edition: Storage fee = Storage unit price per node × Storage capacity per node × Number of nodes × Duration
Different pricing considerations
Alibaba Cloud determines storage pricing for each RDS edition based on its features, availability, and operation and maintenance costs. For example, RDS Cluster Edition benefits from lower unit prices for high-performance cloud disks through bulk purchasing or resource pool optimization. RDS Basic Edition, which uses a single-node architecture, has relatively higher storage costs. These factors contribute to the difference in storage unit prices.
