What Is Amazon DynamoDB?

Welcome to the Amazon DynamoDB Developer Guide.

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. 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.

DynamoDB allows you to delete expired items from tables automatically to help you reduce storage usage 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.

We recommend that you begin by reading the following sections:

To get started quickly with DynamoDB, see Getting Started with DynamoDB.

To learn more about application development see the following:

To quickly find recommendations for maximizing performance and minimizing throughput costs see Best Practices for DynamoDB. To learn how to tag DynamoDB resources see Tagging for DynamoDB.

You can use AWS Database Migration Service to migrate data from a Relational Database or MongoDB to an Amazon DynamoDB table. For more information, see AWS Database Migration Service User Guide. To learn how to use MongoDB as a migration source, see Using MongoDB as a Source for AWS Database Migration Service. To learn how to use DynamoDB as a migration target, see Using an Amazon DynamoDB Database as a Target for AWS Database Migration Service.
