A gaming company uses a NoSQL database to store customer information. The company is planning to migrate to AWS. The company needs a fully managed AWS solution that will handle high online…

Amazon Keyspaces (for Apache Cassandra) is a managed Cassandra-compatible database. While it is fully managed, DynamoDB is generally optimized for broader NoSQL use cases with superior global availability features (Global Tables) and often lower latency guarantees for generic OLTP at scale.

Amazon DocumentDB (with MongoDB compatibility) is a managed document database service. While it offers high availability and scalability, it is specific to document workloads and typically does not offer the same single-digit millisecond performance at extreme scale for OLTP as DynamoDB, nor the same global active-active replication capabilities as DynamoDB Global Tables.

Amazon DynamoDB is a fully managed, serverless NoSQL database service designed for high-performance applications. It consistently delivers single-digit millisecond latency at any scale, offers built-in high availability and durability, and supports global tables for multi-Region, active-active replication, perfectly meeting the requirements with virtually no operational overhead.

Amazon Timestream is a fast, scalable, and serverless time series database. It is optimized for time series data, not general-purpose customer information or high OLTP workloads, making it unsuitable for this use case.
