Amazon Aurora vs Memcached

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.

Memcached is distributed in-memory caching system used to reduce database load by caching frequently accessed data. It provides comprehensive features for databases workflows. The tool is actively maintained with regular updates and strong community/vendor support.
