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. Also, DynamoDB offers encryption at rest, which eliminates the operational burden and complexity involved in protecting sensitive data. For more information, see Amazon DynamoDB Encryption at Rest at https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/EncryptionAtRest.html.

With DynamoDB, you can create database tables that can store and retrieve any amount of data, and serve any level of request traffic. You can scale up or scale down your tables throughput capacity without downtime or performance degradation, and use the AWS Management Console to monitor resource utilization and performance metrics.

Amazon DynamoDB provides on-demand backup capabilities. It allows you to create full backups of your tables for long-term retention and archival for regulatory compliance needs. For more information, see On-Demand Backup and Restore for DynamoDB.

DynamoDB allows you to delete expired items from tables automatically to help you reduce storage use and the cost of storing data that is no longer relevant. For more information, see Time To Live.

DynamoDB automatically spreads the data and traffic for your tables over a sufficient number of servers to handle your throughput and storage requirements, while maintaining consistent and fast performance. All of your data is stored on solid state disks (SSDs) and automatically replicated across multiple availability zones in an AWS region, providing built-in high availability and data durability. You can use global tables to keep DynamoDB tables in sync across AWS regions. For more information, see Global Tables.
