Amazon DynamoDB is a fully managed proprietary NoSQL database service that is offered by as part of the Amazon Web Services portfolio.[1] DynamoDB exposes a similar data model and derives its name from Dynamo, but has a different underlying implementation. Dynamo had a multi-master design requiring the client to resolve version conflicts and DynamoDB use synchronous replication across multiple datacenters [2] for high durability and availability. DynamoDB was announced by Amazon CTO Werner Vogels on January 18, 2012.[3]


DynamoDB differs from other Amazon services by allowing developers to purchase a service based on throughput, rather than storage. Although the database will not scale automatically, administrators can request more throughput and DynamoDB will spread the data and traffic over a number of servers using solid-state drives, allowing predictable performance.[1] It offers integration with Hadoop via Elastic MapReduce.

In September 2013, Amazon made available a local development version of DynamoDB so developers can test DynamoDB-backed applications locally.[4]

It is said to be "built on the principles of Dynamo" (an internal storage system used initially for their own website).[5]

Language bindings[edit]

Languages with DynamoDB binding include Java, Node.js, .NET, Perl, PHP, Python, Ruby, and Erlang.[6]
