AWS NoSQL database service that scales automatically and provides fast performance. Like a super-fast filing system that can handle millions of requests per second.
A gaming app uses DynamoDB to store player scores and achievements, handling millions of players simultaneously.
All are managed NoSQL databases designed for high throughput and low latency. DynamoDB and Cosmos DB are multi-model/key-value style services with automatic scaling options; Bigtable is a wide-column NoSQL database optimized for very large analytical/operational workloads; OCI NoSQL is a managed key-value/document database. Feature sets differ (data models, global replication, query capabilities), but they serve similar needs: fast, scalable NoSQL storage without managing servers.
