Description of editions

Edition Description Scenario Supported engine version
Master-replica Edition The Master-replica Edition uses an architecture that contains one primary instance and up to five read-only instances. If no read-only instance is created, the architecture is cost-effective and is equal to the architecture of the Basic Edition. You can create up to five read-only instances for an ApsaraDB MyBase for MySQL instance of the Master-replica Edition based on your business requirements. Read-only instances do not have replicas and can be used to perform disaster recovery. This helps ensure high stability and high availability, and allows you to perform flexible resource management. For more information, see Master-replica Edition.

  • An architecture that contains one primary instance and multiple read-only instances can be used in scenarios in which production databases are used by medium and large-sized enterprises that send a large number of read requests during peak hours and require intelligent data analysis.
