To reduce costs, a company is planning to migrate a NoSQL database to AWS. Which AWS service is fully managed and can automatically scale throughput capacity to meet database workload demands?
Amazon DynamoDB: DynamoDB is a fully managed NoSQL database service provided by AWS. It is designed to provide low-latency, high-throughput performance for applications. DynamoDB can automatically scale throughput capacity based on the application's demand, making it a suitable choice for workloads with varying traffic patterns.
Amazon Redshift: Amazon Redshift is a fully managed data warehouse service, but it is not a NoSQL database, and its scaling behavior is optimized for analytical queries rather than transactional workloads.
Amazon Aurora: Amazon Aurora is a fully managed relational database service. While it offers automatic scaling, it may not be the optimal choice for a NoSQL database.
Amazon RDS: Amazon RDS (Relational Database Service) is a managed relational database service that supports various database engines. It may not be the best fit for a NoSQL database with automatic scaling requirements.
C is correct. DynamoDB is a non-relational database which means it is a NONSQL database.
Aurora and RDS are relational, as for Redshift that is for exabytes of data and complex queries.
Amazon DynamoDB is a fully managed NoSQL database service that automatically scales to meet the throughput capacity required for your database workloads. DynamoDB provides built-in support for scaling read and write capacity without manual intervention. It also offers on-demand capacity mode that automatically adjusts to your workload demands, making it a cost-effective solution for databases with variable traffic patterns.

Correct answer is C
"Amazon DynamoDB is a fully managed NoSQL database service that provides fast and predictable performance with seamless scalability."
https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/Introduction.html
https://aws.amazon.com/rds/aurora/
if you just opened the Aurora webpage you are going to see that's is MYSQL and PostgreSQL compatibility.
so B is the wrong answer.
right answer is C
"Amazon DynamoDB is a fully managed NoSQL database service that provides fast and predictable performance with seamless scalability."
