What is Amazon RDS?

Amazon Relational Database Service (RDS) is a managed database service that makes it easy to set up, operate, and scale relational databases in the cloud. RDS provides cost-efficient and resizable capacity while automating time-consuming administration tasks such as hardware provisioning, database setup, patching, and backups. It supports multiple database engines including Amazon Aurora, PostgreSQL, MySQL, MariaDB, Oracle, and SQL Server. RDS provides high availability with Multi-AZ deployments, read replicas for scaling read traffic, and automated backup and recovery capabilities.
