Correspondingly, what is Amazon Aurora based on?

Amazon Aurora is a MySQL and PostgreSQL-compatible relational database built for the cloud, that combines the performance and availability of traditional enterprise databases with the simplicity and cost-effectiveness of open source databases.

Also, what is the difference between RDS and Aurora? With Aurora, you can provision up to 15 replicas, and replication is performed in milliseconds. By contrast, RDS allows only five replicas, and the replication process is slower than Amazon Aurora. The replicas on Amazon Aurora use the same logging and storage layers which in turn improve the replication process.

One may also ask, is Aurora based on MySQL?

Amazon Aurora is based on the Open Source MySQL Edition, but is not open source by itself; it is a proprietary, closed-source database.

Is PostgreSQL a relational database?

PostgreSQL, also known as Postgres, is a free and open-source relational database management system (RDBMS) emphasizing extensibility and technical standards compliance. It is designed to handle a range of workloads, from single machines to data warehouses or Web services with many concurrent users.
