- Why am I charged additional fees for a subscription RDS instance?
The fee that you pay for a new subscription RDS instance covers the instance type and the storage capacity. If you create read-only RDS instances, enable the SQL Explorer (SQL Audit) feature or the performance monitoring feature, or consume more storage than the free quota for backup storage, you are charged additional fees. For more information, see the "Billable items" section in this topic.
- Am I charged for a pay-as-you-go RDS instance that I am not using?
Yes, you are charged an hourly fee for every pay-as-you-go RDS instance that you create even if you are not using the RDS instance. A pay-as-you-go RDS instance consumes computing and storage resources even if it is not used. If you do not intend to use a pay-as-you-go RDS instance for a long period of time, we recommend that you save the data that you need and release the RDS instance.
- Is the inbound and outbound Internet traffic that is consumed for my pay-as-you-go
RDS instances and subscription RDS instances free of charge? How much bandwidth is
provided for an RDS instance?
Yes, all inbound and outbound Internet traffic that is consumed for your pay-as-you-go RDS instances and subscription RDS instances is free of charge. The bandwidth of an RDS instance is unlimited.
