Amazon Aurora vs Couchbase

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.

Couchbase is a distributed NoSQL database providing high performance, high availability, and flexible data models for modern applications. It combines document-oriented flexibility with traditional database reliability.
