AWS DynamoDB

Let's imagine we have a large library with thousands of books (data) and a super-efficient librarian (DynamoDB) who can quickly find, store, or update books based on our requests.

Amazon DynamoDB is a fully managed NoSQL database service that provides fast and predictable performance with seamless scalability. It is designed to handle large amounts of data and traffic, making it a great choice for serverless applications using AWS Lambda and Step Functions.
