What is a similarity between Aurora and RDS?

Aurora and RDS (Relational Database Service) share the characteristic of being managed database services offered by AWS. This means that AWS takes care of various administrative tasks for both services, such as hardware provisioning, database setup, patching, backups, and scaling, allowing developers to focus on building applications rather than managing the underlying infrastructure.

Using managed services like Aurora and RDS means that users benefit from high availability, automated backups, and the ability to scale databases in response to varying workloads without needing to spend time on manual management tasks. This managed aspect is critical for organizations looking to save on operational costs and enhance efficiency in their database management processes.

The other options present distinctions between the two services: Aurora is not serverless by default, though it offers a serverless option; they are primarily relational and not designed for NoSQL databases; and while they can be used in big data contexts, their main functions are not focused solely on big data analytics.
