Which service is typically used to provide managed database services on AWS?

Amazon RDS, or Amazon Relational Database Service, is specifically designed for managed database services on AWS. It simplifies the process of setting up, operating, and scaling a relational database in the cloud. Amazon RDS supports multiple database engines, including MySQL, PostgreSQL, MariaDB, Oracle, and SQL Server. It automates essential administrative tasks such as backups, patching, scaling, and replication, allowing users to focus more on application development rather than database management.

The other services mentioned play different roles in the AWS ecosystem. Amazon EC2 is primarily an IaaS (Infrastructure as a Service) offering for running virtual machines, providing complete control over the operating system and software but requiring more management overhead for database tasks. Amazon EKS is a managed Kubernetes service that allows you to run and orchestrate containers but is not specialized for database management. Similarly, Amazon ECS is a container orchestration service that handles Docker containers but does not provide built-in database management features. Therefore, for managed database services, Amazon RDS remains the optimal choice.
