Amazon DynamoDB Ups the Ante for NoSQL Database Service

This past week I watched with great interest as Amazon CTO Werner Vogels announced the launch of Amazon’s DynamoDB service. I feel that rather than trying to say something pithy I will just recommend that you check it out for yourselves.

DynamoDB is a NoSQL database service that is, in my opinion, head and shoulders above what Amazon previously offered with SimpleDB.

DynamoDB removes almost all of the administrative burden associated with provisioning a database for an application. Developers can simply create a database and assume it will be available to store and retrieve any amount of data and serve any level of traffic that may materialize. DynamoDB handles all the load balancing for you transparently behind the scenes.

Unlike some NoSQL databases, DynamoDB gives the developer the choice between strong consistency or eventual consistency on every database transaction. This allows for great control over what happens when data is read or written. Also, DynamoDB has built-in fault tolerance to automatically and synchronously replicate data across multiple Availability Zones.

DynamoDB also integrates with Amazon Elastic Map Reduce. For example it is pretty straightforward to use EMR to analyze data stored in DynamoDB and to archive results in Amazon S3.

DynamoDB is an example of another storage option offered in the cloud. Developers should consider this option for any future development projects they may have.
