          Distributed Relational Database Service DRDS

          Postpaid Billing

          Overview

          In the case of on-demand billing mode for the DRDS, the fees are postpaid. The fees are calculated and deducted in a real-time manner on the basis of minutes and according to your usage. The specific rules are as follows:

          • Billing items: Include storage node memory, storage node disk, read-only replica memory, read-only replica disk, and the number of proxy nodes.
          • In the case of charging by minutes, less than 1 minute is counted as 1 minute.
          • In the case of charging by hours, calculate the fees and generate bills on an hourly basis in the Beijing time. The billing time is within 1 hour after the end of the current billing cycle. For example, the bill for the fee from 10:00 to 11:00 is generated before 12:00, depending on the system's billing time.
          • Before purchase, it is required to ensure that the account has no arrears and that the sum of the account balance and available vouchers is greater than or equal to CNY 100.

          Billing formula

          DRDS cluster price = Storage node price + read-only replica price + proxy node price. Where,

          • Storage node price = Number of storage nodes * (storage node memory unit price * storage node memory + storage node disk unit price * storage node disk)
          • Read-only replica price = Number of storage nodes * number of read-only copies * (read-only replica memory unit price * read-only replica memory + read-only replica disk unit price * read-only replica disk)
          • Proxy node price = Proxy node unit price * number of proxy nodes

          Fee = DRDS cluster price * time
