What is Amazon RDS?

Amazon RDS (Relational Database Service) is a managed database service that simplifies setting up, operating, and scaling relational databases in the cloud. It supports multiple database engines including MySQL, PostgreSQL, MariaDB, Oracle, SQL Server, and Amazon Aurora. RDS automatically handles routine database tasks such as provisioning, patching, backup, recovery, and failure detection. It provides automated backups with point-in-time recovery, read replicas for improved performance, and Multi-AZ deployments for high availability. RDS reduces database administration overhead and allows you to focus on application development.
