Question

 Is it possible for a user to have multiple databases on RDS?

Answer 1

• RDS for MySQL

  No limit imposed by software. The MySQL standard for RDS MySQL database instances is that there is no limit on the number of databases (http://dev.mysql.com/doc/refman/5.5/en/database-count-limit.html).

• RDS for Oracle

  1 database per instance, no limit on number of schemas per database.

• RDS for SQL Server

  30 databases per instance.

• RDS for PostgreSQL

  No limit imposed by software.
