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 a distributed database so that you don’t have to worry about hardware provisioning, setup and configuration, replication, software patching, or cluster scaling.
With DynamoDB, you can create database tables that can store and retrieve any amount of data and serve any level of request traffic. It is designed to run high-performance, internet-scale applications that would overburden traditional relational databases.
- On-demand capacity mode
- Built-in support for ACID transactions
- On-demand backups and point-in-time recovery
- Encryption at rest
