Which AWS service is fully managed and can automatically scale throughput capacity to meet database workload demands?
Amazon Redshift
Amazon Aurora
Amazon DynamoDB
Amazon RDS
Explanations:
Amazon Redshift is a fully managed data warehouse service optimized for online analytical processing (OLAP) and is not designed for NoSQL workloads or automatic scaling of throughput.
Amazon Aurora is a relational database service that is compatible with MySQL and PostgreSQL. While it offers scalability and high performance, it is not a NoSQL database service.
Amazon DynamoDB is a fully managed NoSQL database service that automatically scales throughput capacity based on the workload demands, making it ideal for applications that require flexible data models and automatic scaling.
Amazon RDS (Relational Database Service) is a managed service for relational databases, which does not support NoSQL data models and does not provide automatic scaling specific to NoSQL workloads.
