Amazon DynamoDB REST API

Fully managed NoSQL database service with single-digit latency

Amazon DynamoDB is a fully managed NoSQL database service that provides fast and predictable performance with seamless scalability. DynamoDB lets you offload the administrative burdens of operating and scaling distributed databases, so you don't have to worry about hardware provisioning, setup and configuration, replication, software patching, or cluster scaling. It supports both document and key-value data models with built-in security, backup and restore, and in-memory caching for internet-scale applications.
