Billing Examples

Billing Scenario

A user purchased a pay-per-use replica set DB instance at 15:30:00 on March 18, 2023. The DB instance configuration is as follows:

  • Specifications: 2 vCPUs | 4 GB
  • Number of nodes: 3
  • Storage space: 20 GB
  • EIP bandwidth: 6 Mbit/s

After a period of time, the user found that the current instance class no longer met service requirements and scaled up the storage to 40 GB at 8:00:00 on March 19, 2023, then updated the instance specifications to 4 vCPUs | 8 GB at 9:00:00 on March 20, 2023. Since the user wanted to use the DB instance long term, the user then changed the instance to yearly/monthly billing with a one-month duration at 10:30:00 on the same day. So how much will the user be billed for this DB instance in March and April?
