Amazon Aurora vs Cassandra

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.

Apache Cassandra is an open-source distributed NoSQL database designed for handling large amounts of data across commodity servers with high availability and no single point of failure. It uses a masterless ring architecture with tunable consistency.
