Amazon RDS vs Cloud Firestore

Amazon Relational Database Service (RDS) is a managed database service from AWS that supports MySQL, PostgreSQL, MariaDB, Oracle, SQL Server, and Db2 engines. It automates hardware provisioning, database setup, patching, and backups with options for Multi-AZ deployments and read replicas.

Cloud Firestore is Google's fully-managed NoSQL database for storing and syncing data in real-time across web, mobile, and server applications. It provides powerful querying, automatic scaling, and seamless integration with Firebase services.
