What is the name of Amazon's NoSQL database service launched in 2012?

Amazon's NoSQL database service launched in 2012 is Amazon DynamoDB.

Amazon Web Services introduced DynamoDB on January 18, 2012, as a fully managed database built for applications needing reliable performance at internet scale. It supports key-value and document data models, allowing developers to store flexible records without the fixed table structure associated with traditional relational databases.

The name comes from Amazon's earlier Dynamo research. The original Dynamo system, described in a 2007 paper, was designed to keep Amazon's shopping systems available even when individual servers failed. DynamoDB turned those ideas into a public AWS service, while also adding features such as automatic scaling, managed replication, and encryption.

A common mix-up is Amazon Redshift, which is a cloud data warehouse, not a general-purpose NoSQL database. Amazon Aurora and Amazon RDS are relational database services; Aurora is a database engine, while RDS manages several relational engines. DynamoDB is the answer when the clue emphasizes Amazon, NoSQL, and a 2012 launch.
