- Why am I charged additional fees for a subscription RDS instance?
The fee that you pay when you purchase a subscription RDS instance covers the instance type and the storage capacity that you select. 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 of this topic.
- Am I charged for a pay-as-you-go RDS instance that I do not use?
Yes, you are charged an hourly fee for every pay-as-you-go RDS instance that you create even if you do not use these instances. These instances consume computing resources and storage resources even if you do not use these instances. 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 require and release the RDS instance.
- Am I charged for the inbound and outbound Internet traffic that I consume for my pay-as-you-go
RDS instances and subscription RDS instances ? What is the quota of the bandwidth
plan that is provided for an RDS instance?
You are not changed for the inbound or outbound Internet traffic that you consume for your pay-as-you-go RDS instances and subscription RDS instances. The bandwidth of an RDS instance is unlimited.
