DynamoDB is a perfect fit for the following use cases:
Applications with large amounts of data and strict latency requirements. As your amount of data scales, JOINs, and advanced SQL operations can slow down your queries. With DynamoDB, your questions have predictable latency up to any size, including over 100 TBs!
Serverless applications using AWS Lambda. AWS Lambda provides auto-scaling, stateless, ephemeral computing in response to event triggers. DynamoDB is accessible via an HTTP API and performs authentication & authorization via IAM roles, making it a perfect fit for building Serverless applications.
Data sets with simple, known access patterns. If you’re generating recommendations and serving them to users, DynamoDB’s simple key-value access patterns make it a fast, reliable choice.
