• 正解だと思う選択肢: A

  A. Amazon DynamoDB: A key-value and document database that provides single-digit millisecond latency at any scale. It is a fully managed NoSQL database service designed for applications that require consistent, single-digit millisecond latency, regardless of the volume of requests.

  B. Amazon Aurora: A MySQL and PostgreSQL-compatible relational database engine that offers high performance and availability. While it provides low-latency reads, it is not specifically designed as a key-value database.

  C. Amazon DocumentDB (with MongoDB compatibility): A fully managed document database service that is compatible with MongoDB. It is designed for applications that work with JSON-like documents, and it provides the scalability and availability of a NoSQL database.

  D. Amazon Neptune: A fully managed graph database service that supports graph models. It is designed for applications with highly connected data, and it is not specifically focused on providing sub-millisecond latency for key-value access.
