As a comprehensive database-oriented service, ApsaraDB for Relational Database Service (known as RDS) provides RDS instances in three editions (Basic, High-availability, Cluster (AlwaysOn), and Enterprise) that meet the full scope of database requirements. RDS instances can be operated in the same way as a self-hosted database, which means no additional learning curve is presented.
For short-term requirements, create pay-as-you-go instances (billed by hour), which can be released at any time to save costs.
For long-term requirements, create subscription instances, which are more cost-effective. Furthermore, the longer the subscription, the higher the discount.
On-demand changes to instance specifications
You can upgrade or downgrade instance specifications as needed to make sure that you are only using the resources you require. For more information, see Change configurations and Billing details about configuration change.
