- Why am I charged additional fees for a subscription-billed RDS instance?
The fee that you pay when you create a subscription-billed RDS instance only covers the instance and its storage capacity. If you create read-only RDS instances, enable the SQL Explorer (SQL audit) or performance monitoring feature, or use more storage than that is allowed by the free quota for backup storage, you must pay the additional fees required. For more information, see Billable items.
- Will I be charged for a pay-as-you-go-billed RDS instance that I am not using?
Yes, a pay-as-you-go-billed RDS instance consumes computing and storage resources even if it is not used. Therefore, you are still charged an hourly fee. If you will not use a pay-as-you-go-billed RDS instance for a long period of time, we recommend that you save the required data and then release the instance.
- Is the inbound and outbound Internet traffic consumed for pay-as-you-go- and subscription-billed RDS instances free of charge?
Yes, all of the inbound and outbound Internet traffic that is consumed for pay-as-you-go- and subscription-billed RDS instances is free of charge.
