Amazon Aurora vs Amazon RDS

Amazon Aurora is a MySQL and PostgreSQL-compatible relational database service built for the cloud, offered as part of Amazon Web Services. It provides up to five times the throughput of standard MySQL and three times that of PostgreSQL with automatic scaling, replication, and backup.

Amazon Relational Database Service (RDS) is a managed database service from AWS that supports MySQL, PostgreSQL, MariaDB, Oracle, SQL Server, and Db2 engines. It automates hardware provisioning, database setup, patching, and backups with options for Multi-AZ deployments and read replicas.
