Other Databases

Amazon Aurora is a fully managed, MySQL and PostgreSQL-compatible relational database service built for the cloud. It combines the performance and availability of high-end commercial databases with the simplicity and cost-effectiveness of open-source databases, offering up to five times the throughput of standard MySQL and three times that of PostgreSQL. Aurora automatically handles tasks like hardware provisioning, database setup, patching, backups, and replication, while providing high durability and availability through distributed, fault-tolerant, self-healing storage.

Apache Cassandra is a highly scalable, distributed NoSQL database designed to handle large amounts of data across many commodity servers, providing high availability with no single point of failure. It uses a decentralized, peer-to-peer architecture with a masterless design, making it fault-tolerant and suitable for mission-critical applications. Cassandra's data model is based on a wide-column store, offering flexible schema design and efficient read/write operations for time-series, IoT, and real-time analytics workloads.
