Yearly/Monthly |
Storage type change |
You will be billed for the new storage type based on the time remaining in the requested period of your instance.
The following prices are for reference only. The actual prices are displayed on the console. Suppose you purchased a one-month RDS for MySQL 8.0 primary/standby instance (instance class: general-purpose, 2 vCPUs | 4 GB; storage: cloud SSD, 40 GB) in CN-Hong Kong on August 1, 2024. The instance price was $88.69 USD per month. On August 15, 2024, you changed the storage type to extreme SSD. The instance price became $103.67 USD per month. Price difference = Price for the new storage type x Remaining period – Price for the original storage type x Remaining period Remaining period = Remaining days of each calendar month/Maximum number of days in each calendar month In this example, the remaining period and price difference are calculated as follows: Remaining period = 15 (Remaining days in August)/30 (Maximum number of days in August) = 0.5. Price difference = $103.67 USD x 0.5 - $88.69 USD x 0.5 = $7.49 USD |
