• A database instance is uniquely defined by its database IP address and port.

  The number of database instances equals the number of database ports. If a database IP address has N database ports, there are N database instances.

  Example: A user has two database IP addresses, IP₁ and IP₂. IP₁ has a database port. IP₂ has three database ports. IP₁ and IP₂ have four database instances in total. To audit all of them, select professional edition DBSS, which supports a maximum of six database instances.

• To change the edition of a DBSS instance, unsubscribe from it and apply for a new one.
• The cloud native edition can be purchased only on the RDS console.
• Online SQL statements are counted based on the assumption that the capacity of an SQL statement is 1 KB.
