RDS editions of ApsaraDB RDS for PostgreSQL
Description of RDS editions of ApsaraDB RDS for SQL Server
RDS editions of ApsaraDB RDS for MariaDB
RDS edition | Description | Scenario |
RDS Basic Edition | | |
RDS High-availability Edition | The database system consists of a primary RDS instance and a secondary RDS instance. These instances work in HA mode and support automatic failover. The secondary RDS instance cannot be accessed. You can create read-only RDS instances to increase the read capability of your database system. For more information, see Create a read-only ApsaraDB RDS for MySQL instance.
| Production databases for large and medium-sized enterprises Databases that are used in industries such as the Internet, IoT, e-commerce, logistics, and gaming
|
RDS Cluster Edition | The database system consists of a primary RDS instance and multiple secondary RDS instances. These instances work in HA mode and support automatic failover. The secondary RDS instances can be accessed. This increases the read capability of your database system. You can create multiple secondary RDS instances to increase the read capability of your database system.
| Production databases for large and medium-sized enterprises Databases that are used in industries such as Internet-based new retail and automobile manufacturing, and databases that are used for Enterprise Resource Planning (ERP) systems

RDS edition | Description | Scenario |
RDS Basic Edition | | |
RDS High-availability Edition | The database system consists of a primary RDS instance and a secondary RDS instance. These instances work in high availability (HA) mode and support automatic failover. The secondary RDS instance cannot be accessed. Read-only RDS instances are not supported.
| Production databases for large and medium-sized enterprises Databases that are used in industries such as the Internet, IoT, e-commerce, logistics, and gaming
|
RDS Cluster Edition | The database system consists of a primary RDS instance and a secondary RDS instance. These instances work in HA mode and support automatic failover. The secondary RDS instances can be accessed. This increases the read capability of your database system. You can create up to seven read-only RDS instances to improve the read capability. However, read-only RDS instances do not participate in the primary instance election or workload switchover. For more information, see Create a read-only ApsaraDB RDS for SQL Server instance.
