Which service is an example of a serverless database offered by AWS?

Amazon Aurora Serverless is an ideal example of a serverless database offered by AWS because it automatically scales the database's compute capacity up or down based on the application's needs. This means that users do not have to provision and manage database instances manually or worry about fluctuations in workload; instead, they pay only for the resources consumed. This on-demand scaling and billing model exemplifies the core features of serverless architecture.

While Amazon DynamoDB is also a serverless option, it is structured more as a NoSQL database than a relational one, which may lead to some confusion regarding the definition of a "serverless database" in the context of relational database services. On the other hand, Amazon RDS and AWS Redshift are traditional database services that require provisioning and management of instances, thus they do not fall under the serverless category.
