Amazon DynamoDB is a fully-managed NoSQL database service, so you don't have to worry about hardware provisioning, setup and configuration, replication, software patching, or cluster scaling.
Amazon DynamoDB uses partitioning, which is a mechanism that allows the database to scale horizontally, and distribute large amounts of data across multiple servers while ensuring quick data access and high availability.
