Amazon RDS
#50 · Level 2 · Scaling and resilience · DatabaseConcept
Section titled “Concept”Amazon RDS is a managed relational database service, where AWS runs databases such as MySQL, PostgreSQL, SQL Server, Oracle and MariaDB for you. Each running database is called a DB instance. AWS takes care of backups, software patches and hardware, but the database design and the data are your responsibility. If you turn on Multi-AZ, a standby database is kept ready in another Availability Zone. To handle heavy reading, you can create read-only copies called read replicas.
