Which AWS service is the managed relational database service?

Amazon RDS (Relational Database Service) is the fully managed relational database offering from AWS. It supports popular engines such as MySQL, PostgreSQL, MariaDB, Oracle, and Microsoft SQL Server. RDS handles routine administrative tasks like provisioning, patching, backups, and replication, allowing developers to focus on application logic. It also provides features such as automated scaling, multi‑AZ high availability, and read replicas for performance. Because it is managed, you can focus on schema design and application logic rather than database maintenance. RDS integrates with other AWS services like IAM for fine‑grained access control and CloudWatch for monitoring. Its support for multiple database engines makes it a versatile choice for legacy and new applications. RDS also offers automated backups, point‑in‑time recovery, and read replicas for scaling read workloads. With RDS, you can also enable encryption at rest and in transit using AWS Key Management Service (KMS) and SSL/TLS, ensuring data confidentiality. RDS supports automated failover and read‑replica promotion, which helps maintain high availability and reduce downtime during maintenance windows.
