Q: What Bills Are Generated After the Billing Mode of an RDS DB Instance Is Changed from Pay-per-Use to Yearly/Monthly?

A: Suppose you bought a pay-per-use DB instance at 15:29:16 on April 18, 2023 and changed it to yearly/monthly billing at 16:30:30 on the same day. After you paid for the order, yearly/monthly billing was applied immediately. On the Billing Center > Billing page, three line items were generated, one for each of the hours the DB instance was used on a pay-per-use basis, and one for the yearly/monthly subscription:

• Pay-per-use expenditures for 15:29:16 to 16:00:00 on April 18, 2023
• Pay-per-use expenditures for 16:00:00 to 16:30:30 on April 18, 2023
• A single, yearly/monthly expenditure generated on April 18, 2023, 16:30:30
