1. TL;DR & Problem Statement
Definition: A fully managed database service providing automated provisioning, high availability, patching, backups, and horizontal read scalability for relational engines (PostgreSQL, MySQL, MariaDB, Oracle, SQL Server, and Amazon Aurora).
Problem Solved: Eliminates the operational complexity, data-loss risk, and administrative overhead of running stateful database clusters inside self-managed containers or bare EC2 instances (e.g., storage corruption, manual failover scripts, snapshot replication, and split-brain scenarios).
